Configuring the fieldbus 6.2 Communication via RS485 6.2.3 Communication over Modbus RTU Overview of communication using Modbus The Modbus protocol is a communication protocol with linear topology based on a master/slave architecture. Modbus offers three transmission modes: ● Modbus ASCII Data is transferred in ASCII code. The data can therefore be read directly by humans, however, the data throughput is lower in comparison to RTU.
Configuring the fieldbus 6.2 Communication via RS485 6.2.3.1 Setting the address You can set the inverter's Modbus RTU address using either DIP switches on the Control Unit or parameter p2021. Valid Modbus RTU addresses: 1 … 247 Invalid Modbus RTU addresses: 0 If you have specified a valid address using DIP switches, this address will always be the one that takes effect and p2021 cannot be changed. If you set all DIP switches to "OFF" (0) or "ON" (1), then p2021 defines the address.
Configuring the fieldbus 6.2 Communication via RS485 6.2.3.3 Modbus RTU telegram Description For Modbus, there is precisely one master and up to 247 slaves. Communication is always triggered by the master. The slaves can only transfer data at the request of the master. Slave-to-slave communication is not possible. The Control Unit always operates as slave. The following figure shows the structure of a Modbus RTU telegram.
Configuring the fieldbus 6.2 Communication via RS485 6.2.3.4 Baud rates and mapping tables Permissible baud rates and telegram delay The Modbus RTU telegram requires a pause for the following cases: ● Start detection ● Between the individual frames ● End detection Minimum duration: Processing time for 3.5 bytes (can be set via p2024[2]). A character delay time is also permitted between the individual bytes of a frame. Maximum duration: Processing time for 1.5 bytes (can be set via p2024[1]).

CAUTION Changes made to the node ID or baud rate only become effective after switching off and on again. It is particularly important that any external 24 V supply is switched off. Note that before turning off, you must save the changes using RAM -> ROM ( ).
Configuring the fieldbus 6.3 Communication over CANopen 6.3.2.2 Monitoring the communication and response of the inverter The communication monitoring can be used via both node guarding and heartbeat protocol (heartbeat producer). Node guarding The master sends monitoring queries to the slaves via the node guarding protocol. If the converter does not receive a Node Guarding protocol within the Life Time, then it outputs fault (F08700). Life Time = Guard time (p8601.0) * Life Time Factor (p8604.
Configuring the fieldbus 6.3 Communication over CANopen 6.3.2.3 SDO services You can access the object directory of the connected drive unit using the SDO services. An SDO connection is a peer-to-peer coupling between an SDO client and a server. The drive unit with its object directory is an SDO server. The identifiers for the SDO channel of a drive unit are defined according to CANopen as follows.

Configuring the fieldbus 6.3 Communication over CANopen Not all of the parameters can be directly addressed via this range. This is the reason that in CAN, an inverter parameter always comprises two parameters from the inverter; these are the offset specified using parameter p8630[2] and the parameter itself.
Configuring the fieldbus 6.3 Communication over CANopen 6.3.2.5 PDO and PDO services Process data objects (PDO) For CANopen, (real-time) transfer of process data is realized using "Process Data Objects" (PDO). There are send and receive PDO. With the G120 inverter, eight send PDO (TPDO) and eight receive PDO (RPDO) are transferred. A PDO is defined by the PDO communication parameter and the PDO mapping parameter. The PDO must be linked with the objects of the object dictionary which contain process data.
Configuring the fieldbus 6.3 Communication over CANopen The structure of this communication and mapping parameter is listed in the following tables.
Configuring the fieldbus 6.3 Communication over CANopen Synchronous data transmission In order for the devices on the CANopen bus to remain synchronized during transmission, a synchronization object (SYNC object) must be transmitted at periodic intervals. Each PDO that is transferred as a synchronous object must be assigned a transmission type 1 ... n. The following is applicable: ● Transmission type 1: the PDO is transferred in every SYNC cycle.
Configuring the fieldbus 6.3 Communication over CANopen PDO services The PDO services can be subdivided as follows: ● Write PDO ● Read PDO ● SYNC service Write PDO The "Write PDO" service is based on the "push" model. The PDO has exactly one producer. There can be no consumer, one consumer, or multiple consumers. Via Write PDO, the producer of the PDO sends the data of the mapped application object to the individual consumer. Read PDO The "Read PDO" service is based on the "pull" model.
Configuring the fieldbus 6.3 Communication over CANopen 6.3.2.6 Predefined connection set When integrating the converter via the predefined connection set, the converter is interconnected so that the motor can be switched-on via the control and a setpoint can be entered without having to make any additional settings or requiring CANopen know-how. The converter returns the status word and the speed actual value to the control. In the factory, the converter is set to free PDO mapping.
Configuring the fieldbus 6.3 Communication over CANopen 6.3.2.7 Free PDO mapping Using the free PDO mapping, you can interconnect additional process data from the object directory corresponding to the requirements of your particular system for the PDO service. In the factory, the converter is set to free PDO mapping. If your converter has been changed over to the Predefined Connection Set, you must change over to free PDO mapping, see Section PDO and PDO services (Page 161).
Configuring the fieldbus 6.3 Communication over CANopen 6.3.3 Other CANopen functions 6.3.3.1 Network management (NMT service) Network management (NMT) is node-oriented and has a master-slave topology. The NMT services can be used to initialize, start, monitor, reset, or stop nodes. Two data bytes follow each NMT service. All NMT services have the COB ID = 0. This cannot be changed.
Configuring the fieldbus 6.3 Communication over CANopen The NMT recognizes the following transitional states: ● Start Remote Node: command for switching from the "Pre-Operational" communication status to "Operational". The drive can only transmit and receive process data (PDO) in "Operational" status. ● Stop Remote Node command for switching from "Pre-Operational" or "Operational" to "Stopped". The node can only process NMT commands in the "Stopped" status.

Functions 7.2 Inverter control 7.2 Inverter control If you are controlling the inverter using digital inputs, you use parameter p0015 during basic commissioning to define how the motor is switched on and off and how it is changed over from clockwise to counter-clockwise rotation. Five different methods are available for controlling the motor. Three of the five methods just require two control commands (two-wire control). The other two methods require three control commands (three-wire control).
Functions 7.2 Inverter control 7.2.1 Two-wire control: method 1 You switch the motor on and off using a control command (ON/OFF1). while the other control command reverses the motor direction of rotation. 21 2)) W 5HYHUVLQJ W 6HWSRLQW 0RWRU VSHHG &ORFNZLVH URWDWLRQ &RXQWHU FORFNZLVH URWDWLRQ W ,QYHUWHG VHWSRLQW Figure 7-2 Two-wire control, method 1 Table 7- 2 Function table 2)) 2)) ON/OFF1 Reversing 0 0 OFF1: The motor stops. 0 1 OFF1: The motor stops.
Functions 7.2 Inverter control 7.2.2 Two-wire control, method 2 You switch the motor on and off using a control command (ON/OFF1) and at the same time select clockwise motor rotation. You also use the other control command to switch the motor on and off, but in this case you select counter-clockwise rotation for the motor. The inverter only accepts a new control command when the motor is at a standstill.
Functions 7.2 Inverter control 7.2.3 Two-wire control, method 3 You switch the motor on and off using a control command (ON/OFF1) and at the same time select clockwise motor rotation. You also use the other control command to switch the motor on and off, but in this case you select counter-clockwise rotation for the motor. Unlike method 2, the inverter will accept the control commands at any time, regardless of the motor speed.
Functions 7.2 Inverter control 7.2.4 Three-wire control, method 1 With one control command, you enable the two other control commands. You switch the motor off by canceling the enable (OFF1). You switch the motor's direction of rotation to clockwise rotation with the positive edge of the second control command. If the motor is still switched off, switch it on (ON). You switch the motor's direction of rotation to counter-clockwise rotation with the positive edge of the third control command.
Functions 7.2 Inverter control 7.2.5 Three-wire control, method 2 With one control command, you enable the two other control commands. You switch the motor off by canceling the enable (OFF1). You switch on the motor with the positive edge of the second control command (ON). The third control command defines the motor's direction of rotation (reversing).
Functions 7.2 Inverter control 7.2.6 Switching over the inverter control (command data set) In several applications, the inverter must be able to be operated from different, higher-level control systems. Example: Switchover from automatic to manual operation A motor is switched on and off and its speed varied either from a central control system via a fieldbus or from a local control box.
Functions 7.2 Inverter control You select the command data set using parameter p0810. To do this, you must interconnect parameter p0810 with a control command of your choice, e.g. a digital input. &RPPDQG GDWD VHW 3DUDPHWHU ZLWK LQGH[ > @ &RQWURO ZRUG %LW 352),%86 p0840[0] r2090.0 p2103[0] r2090.7 21 2)) $FNQRZOHGJH ,QYHUWHU FRQWURO p0854[0] &RQWURO 3/& r2090.10 &'6 p1036[0] 023 GRZQ r2090.
Functions 7.2 Inverter control Advanced settings If you require more than two command data sets, then define the number of command data sets (2, 3 or 4) using parameter p0170.
Functions 7.3 Command sources 7.3 Command sources The command source is the interface via which the inverter receives its control commands. When commissioning, you define this using macro 15 (p0015). Note The "Get master control" or "Manual/Auto changeover" function can also be used to specify commands and setpoints via STARTER or the Operator Panel. Change command source If you subsequently change the command source using macro 15, then you must carry out commissioning again.
Functions 7.4 Setpoint sources 7.4 Setpoint sources The setpoint source is the interface via which the inverter receives its setpoint. The following options are available: ● Motorized potentiometer simulated in the inverter. ● Inverter analog input. ● Setpoints saved in the inverter: – Fixed setpoints – Jog ● Inverter fieldbus interface. Depending on the parameterization, the setpoint in the inverter has one of the following meanings: ● Speed setpoint for the motor. ● Torque setpoint for the motor.
Functions 7.4 Setpoint sources 7.4.2 Motorized potentiometer as setpoint source The 'motorized potentiometer' (MOP) function simulates an electromechanical potentiometer for entering setpoints. You can continuously adjust the motorized potentiometer (MOP) using the control signals "raise" and "lower". The control signals are received via the digital inputs of the inverter or from the operator panel that has been inserted. Typical applications ● Entering the speed setpoint during the commissioning phase.
Functions 7.
Functions 7.4 Setpoint sources Example of parameterization of the motorized potentiometer Table 7- 18 7.4.3 Implementing a motorized potentiometer using digital inputs Parameter Description p0015 = 9 Macro drive unit: Configure inverter on MOP as the setpoint source • The motor is switched on and off via digital input 0. • The MOP setpoint is increased via digital input 1. • The MOP setpoint is decreased via digital input 2.
Functions 7.4 Setpoint sources The various fixed setpoints can be selected in two ways: 1. Direct selection: Precisely one fixed speed setpoint is assigned to each selection signal (e.g. a digital input). As several selection signals are selected, the associated fixed speed setpoints are added together to from a total setpoint. Direct selection is particularly well suited to controlling the motor using the inverter's digital inputs. 2.
Functions 7.4 Setpoint sources Example: Selecting two fixed speed setpoints using digital input 2 and digital input 3 The motor is to run at two different speeds: ● The motor is switched on with digital input 0 ● When digital input 2 is selected, the motor is to run at a speed of 300 rpm. ● When digital input 3 is selected, the motor is to accelerate to a speed of 2000 rpm. ● When digital input 1 is selected, the motor should go into reverse Table 7- 21 7.4.
Functions 7.4 Setpoint sources Table 7- 22 Parameters for the "Jog" function Parameter Description p1055 Signal source for jogging 1 - jog bit 0 (factory setting: 0) If you wish to jog via a digital input, then set p1055 = 722.x p1056 Signal source for jogging 2 - jog bit 1 (factory setting: 0) If you wish to jog via a digital input, then set p1056 = 722.x 7.4.
Functions 7.5 Setpoint calculation 7.5 Setpoint calculation The setpoint processing modifies the speed setpoint, e.g. it limits the setpoint to a maximum and minimum value and using the ramp-function generator prevents the motor from executing speed steps. 3RVLWLYH /LPLWDWLRQ 5DPSXS WLPH 5DPS GRZQ WLPH 6SHHG VHWSRLQW IRU PRWRU FRQWURO 6SHHG VHWSRLQW IURP VHWSRLQW VRXUFH 5DPS IXQFWLRQ JHQHUDWRU QHJDWLYH /LPLWDWLRQ Figure 7-10 7.5.
Functions 7.5 Setpoint calculation 7.5.2 Ramp-function generator The ramp-function generator in the setpoint channel limits the speed of changes to the speed setpoint. The ramp-function generator does the following: ● The soft acceleration and braking of the motor reduces the stress on the mechanical system of the driven machine. ● Acceleration and braking distance of the driven machine (e.g. a conveyor belt) are independent of the motor load.
Functions 7.6 Motor control 7.6 0 Motor control For induction motors, there are two different open-loop control or closed-loop control techniques: ● Open-loop control with V/f-characteristic (V/f control) ● Field-oriented control (vector control) Criteria for selecting either V/f control or vector control V/f control is perfectly suitable for almost any application in which the speed of induction motors is to be changed.
Functions 7.
Functions 7.6 Motor control 7.6.1 V/f control V/f control sets the voltage at the motor terminals on the basis of the specified speed setpoint. The relationship between the speed setpoint and stator voltage is calculated using characteristic curves. The required output frequency is calculated on the basis of the speed setpoint and the number of pole pairs of the motor (f = n * number of pole pairs / 60, in particular: fmax = p1082 * number of pole pairs / 60).
Functions 7.6 Motor control 7.6.1.2 Additional characteristics for the V/f control In addition to linear and square-law characteristics, there are the following additional versions of the V/f control that are suitable for special applications. Linear V/f characteristic with Flux Current Control (FCC) (P1300 = 1) Voltage losses across the stator resistance are automatically compensated. This is particularly useful for small motors since they have a relatively high stator resistance.
Functions 7.6 Motor control V/f control for drives requiring a precise frequency (textile industry) (p1300 = 5), V/f control for drives requiring a precise frequency and FCC (p1300 = 6) These characteristics require the motor speed to remain constant under all circumstances. This setting has the following effects: ● When the maximum current limit is reached, the stator voltage is reduced but not the speed. ● Slip compensation is locked.
Functions 7.6 Motor control Note Only increase the voltage boost in small steps until satisfactory motor behavior is reached. Excessively high values in p1310 ... p1312 can cause the motor to overheat and switch off (trip) the inverter due to overcurrent . Table 7- 25 Optimizing the starting characteristics for a linear characteristic Parameter Description P1310 Permanent voltage boost (factory setting 50 %) The voltage boost is active from standstill up to the rated speed.
Functions 7.6 Motor control 7.6.2 Vector control 7.6.2.1 Properties of vector control Using a motor model, the vector control calculates the load and the motor slip. As a result of this calculation, the inverter controls its output voltage and frequency so that the motor speed follows the setpoint, independent of the motor load. Vector control is possible without directly measuring the motor speed. This closed-loop control is also known as sensorless vector control. 7.6.2.
Functions 7.6 Motor control 7.6.2.3 Torque control Torque control is part of the vector control and normally receives its setpoint from the speed controller output. By deactivating the speed controller and directly entering the torque setpoint, the closed-loop speed control becomes closed-loop torque control. The inverter then no longer controls the motor speed, but the torque that the motor generates.
Functions 7.7 Protection functions 7.7 Protection functions The frequency inverter offers protective functions against overtemperature and overcurrent for both the frequency inverter as well as the motor. Further, the frequency inverter protects itself against an excessively high DC link voltage when the motor is regenerating. 7.7.
Functions 7.7 Protection functions 7.7.2 Motor temperature monitoring using a temperature sensor You can use one of the following sensors to protect the motor against overtemperature: ● PTC sensor ● KTY 84 sensor ● ThermoClick sensor The motor's temperature sensor is connected to the Control Unit. Temperature measurement via PTC The PTC sensor is connected to terminals 14 and 15. ● Overtemperature: The threshold value to switch over to an alarm or fault is 1650 Ω.
Functions 7.
Functions 7.7 Protection functions 7.7.3 Protecting the motor by calculating the motor temperature The temperature calculation is only possible in the vector control mode (P1300 ≥ 20) and functions by calculating a thermal motor model.
Functions 7.7 Protection functions Settings You only have to change the factory settings of the Imax controller if the drive tends to oscillate when it reaches the current limit or it is shut down due to overcurrent. Table 7- 30 Imax controller parameters Parameter Description P0305 Rated motor current P0640 Motor current limit P1340 Proportional gain of the Imax controller for speed reduction P1341 Integral time of the Imax controller for speed reduction r0056.
Functions 7.7 Protection functions There are two different groups of parameters for the VDCmax controller, depending on whether the motor is being operated with U/f control or vector control.
Functions 7.8 Status messages 7.8 Status messages Information about the inverter state (alarms, faults, actual values) can be output via inputs and outputs and also via the communication interface. Details on evaluating the inverter state via inputs and outputs are provided in Section Adapting the terminal strip (Page 85). The evaluation of the inverter state via the communication interface is realized using the inverter status word.
Functions 7.9 Application-specific functions 7.9 Application-specific functions The inverter offers a series of functions that you can use depending on your particular application, e.g.: ● Unit changeover ● Braking functions ● Automatic restart and flying restart ● Basic process control functions ● Logical and arithmetic functions using function blocks that can be freely interconnected Please refer to the following sections for detailed descriptions.
Functions 7.9 Application-specific functions Note Restrictions for the unit changeover function • The values on the rating plate of the inverter or motor cannot be displayed as percentage values. • Using the unit changeover function a multiple times (for example, percent → physical unit 1 → physical unit 2 → percent) may lead to the original value being changed by one decimal place as a result of rounding errors.

Functions 7.9 Application-specific functions 7.9.1.3 Changing over process variables for the technology controller Note We recommend that the units and reference values of the technology controller are coordinated and harmonized with one another during commissioning. Subsequent modification in the reference variable or the unit can result in incorrect calculations or displays.
Functions 7.9 Application-specific functions 7.9.1.4 Changing of the units with STARTER The converter must be in the offline mode in order to change over the units. STARTER shows whether you change settings online in the converter or change offline in the PC ( / ).

Functions 7.9 Application-specific functions 7.9.2 Braking functions of the converter 7.9.2.1 Comparison of electrical braking methods Regenerative power If an induction motor electrically brakes the connected load and the mechanical power exceeds the electrical losses, then it operates as a generator. The motor converts mechanical power into electrical power.
Functions 7.9 Application-specific functions Main features of the braking functions DC braking The motor converts the regenerative power into heat.
Functions 7.9 Application-specific functions The inverter feeds the regenerative power back into the line supply. /LQH • Advantages: Constant braking torque; the regenerative power is not converted into heat, but is regenerated into the line supply; can be used in all applications; continuous regenerative operation is possible - e.g.
Functions 7.9 Application-specific functions 7.9.2.2 DC braking DC braking is used for applications without regenerative feedback into the line supply, where the motor can be more quickly braked by impressing a DC current than along a braking ramp. Typical applications for DC braking include: ● Centrifuges ● Saws ● Grinding machines ● Conveyor belts Whether DC braking or ramp-down with an OFF1 command is more effective depends on the motor properties.
Functions 7.9 Application-specific functions The following operating modes are available for DC braking.
Functions 7.9 Application-specific functions Activating DC braking independent of the speed using a control command DC braking starts independent of the motor speed, as soon as the control command for braking (e.g. via DI3: P1230 = 722.3) is issued. If the braking command is revoked, the inverter returns to normal operation and the motor accelerates to its setpoint. Note: The value of p1230 is displayed in r1239.11.

Functions 7.9 Application-specific functions 7.9.2.3 Compound braking Compound braking is typically used for applications in which the motor is normally operated at a constant speed and is only braked down to standstill in longer time intervals, e.g.
Functions 7.9 Application-specific functions Parameterizing compound braking Table 7- 37 Parameters to enable and set compound braking Parameter Description P3856 Compound braking current (%) With the compound braking current, the magnitude of the DC current is defined, which is additionally generated when stopping the motor for operation with V/f control to increase the braking effect.
Functions 7.9 Application-specific functions 7.9.2.4 Dynamic braking Dynamic braking is typically used in applications in which dynamic motor behavior is required at different speeds or continuous direction changes, e.g.: ● Horizontal conveyors ● Vertical and inclined conveyors ● Hoisting gear Principle of operation The inverter controls the braking chopper depending on its DC link voltage. The DC link voltage increases as soon as the inverter absorbs the regenerative power when braking the motor.
Functions 7.9 Application-specific functions ● Evaluate the braking resistor's temperature monitoring (terminals T1 and T2) such that the motor is switched off when the resistor experiences overtemperature. You can do this in the following two ways: – Use a contactor to disconnect the converter from the line as soon as the temperature monitoring responds. – Connect the contact of the temperature monitoring function of the braking resistor with a free digital input of your choice on the converter.
Functions 7.9 Application-specific functions 7.9.2.5 Braking with regenerative feedback to the line Regenerative braking is typically used in applications where braking energy is generated either frequently or for longer periods of time, e.g.: ● Centrifuges ● Unwinders ● Cranes and hoisting gear Pre-requisite for regenerative braking is the Power Module PM250 or PM260.
Functions 7.9 Application-specific functions 7.9.3 Automatic restart and flying restart 7.9.3.1 Flying restart – switching on while the motor is running If you switch on the motor while it is still running, then with a high degree of probability, a fault will occur due to overcurrent (overcurrent fault F07801). Examples of applications involving an unintentionally rotating motor directly before switching on: ● The motor rotates after a brief line interruption. ● A flow of air turns the fan impeller.
Functions 7.9 Application-specific functions Table 7- 40 Advanced settings Parameter Description P1201 Flying restart enable signal source (factory setting: 1) Defines a control command, e.g. a digital input, through which the flying restart function is enabled. P1202 Flying restart search current (Factory setting for Power Module PM230: 90 %.
Functions 7.9 Application-specific functions 7.9.3.2 Automatic switch-on The automatic restart includes two different functions: 1. The inverter automatically acknowledges faults. 2. After a fault occurs or after a power failure, the inverter automatically switches-on the motor again. This automatic restart function is primarily used in applications where the motor is controlled locally via the inverter's inputs.
Functions 7.9 Application-specific functions ● Set the parameters of the automatic restart function. The method of operation of the parameters is explained in the following diagram and in the table.

Functions 7.9 Application-specific functions Parameter Explanation p1213[0] Automatic restart monitoring time for restart (factory setting: 60 s) This parameter is only effective for the settings p1210 = 4, 6, 14, 16, 26. With this monitoring function, you limit the time in which the inverter may attempt to automatically switch-on the motor again. The monitoring function starts when a fault is identified and ends with a successful start attempt.
Functions 7.9 Application-specific functions 7.9.4 PID technology controller The technology controller permits all types of simple process controls to be implemented. You can use the technology controller for e.g. pressure controllers, level controls or flow controls.
Functions 7.9 Application-specific functions 7.9.5 Load torque monitoring (system protection) In many applications, it is advisable to monitor the motor torque: ● Applications where the load speed can be indirectly monitored by means of the load torque. For example, in fans and conveyor belts too low a torque indicates that the drive belt is torn. ● Applications that are to be protected against overload or locking (e.g. extruders or mixers).
Functions 7.9 Application-specific functions Table 7- 43 Parameterizing the monitoring functions Parameter Description No-load monitoring P2179 Current limit for no-load detection If the converter current is below this value, the message "no load" is output.
Functions 7.9 Application-specific functions 7.9.6 Load failure monitoring via digital input Using this function, the inverter monitors the load failure of the driven machine, e.g. for fans or conveyor belts.
Functions 7.9 Application-specific functions 7.9.7 Real time clock (RTC) The real time clock is the basis for time-dependent process controls, e.g.: ● To reduce the temperature of a heating control during the night ● Increase the pressure of a water supply at certain times during the day Real time clock: Format and commissioning The real time clock starts as soon as the Control Unit power supply is switched on for the first time.
Functions 7.9 Application-specific functions Accept the real time clock in the alarm and fault buffer Using the real time clock, you can track the sequence of alarms and faults over time. When an appropriate message occurs, the real time clock is converted into the UTC time format (Universal Time Coordinated): Date, time ⇒ 01.01.
Functions 7.9 Application-specific functions 7.9.8 Time switch (DTC) The "time switch" (DTC) function, along with the real time clock in the inverter, offers the option of controlling when signals are switched on and off. Examples: ● Day/night switching of a temperature control ● Switching a process control from weekday to weekend. Principle of operation of the time switch (DTC) The inverter has three independent parameterizable time switches.
Functions 7.9 Application-specific functions 7.9.9 Temperature sensing using temperature-dependent resistors Analog input AI 2 Analog input AI 2 can be used as a current input or resistance input for a temperature sensor. Both the DIP switch and parameter p0756.2 must be set accordingly for this purpose. ● P0756.2 = 2 or 3 -> options for setting as current input ● P0756.
Functions 7.9 Application-specific functions Note If a temperature sensor is used as an input for the PID controller, the scaling of the analog input must be adjusted. • Scaling example for NI1000: 0 °C (p0757) = 0 % (p0758); 100 °C (p0759) = 100 % (p0760) • Scaling example for PT1000: 0 °C (p0757) = 0 % (p0758); 100 °C (p0759) = 80 % (p0760) Please refer to the parameter list for more details.
Functions 7.9 Application-specific functions 7.9.10 Essential service mode The Essential Service Mode (ESM) function ensures that when required, the motor is operated for as long as possible so that, for example, smoke gases can be extracted or people affected by a fire can escape. Application example In order to improve air circulation in stairwells, frequently, a slight underpressure is generated using ventilation control. With this control, a fire would mean that smoke gases enter into the stairwell.
Functions 7.9 Application-specific functions You will find additional details on this in the List Manual in the function diagrams for essential service mode, setpoint channel and technology controller. When in the factory setting, if the setpoint is lost, the drive continues using the last recognized setpoint.
Functions 7.9 Application-specific functions Special features of the essential service mode ● The automatic restart function is internally activated – independent of the setting of p1210 – as soon as the essential service mode kicks in. This results in the inverter being restarted if a pulse inhibit (OFF2) occurs due to an internal fault. ● In the essential service mode, inverter shutdown due to faults is suppressed, with the exception of faults that would lead to the destruction of the inverter.
Functions 7.9 Application-specific functions Table 7- 45 Parameters that are required to set the essential service mode Parameter Description Setting the source for the essential service mode p3880 = 722.3 ESM activation (here, via DI3, high-active) Signal source for activating the essential service mode 722.x for high active, 723.
Functions 7.
Functions 7.9 Application-specific functions 7.9.11 Multi-zone control Multi-zone control is used to control quantities such as pressure or temperature via the technology setpoint deviation. The setpoints and actual values are fed in via the analog inputs as current (0 … 20 mA) or voltage (0 … 10 V) or as a percentage via temperaturedependent resistances (NI1000 / PT1000, 0 °C = 0 %; 100 °C = 100 %).
Functions 7.9 Application-specific functions Day and night switching Using a day/night changeover other setpoints can be entered for specific times. The day/night changeover control can be realized e.g. using an external signal via DI4 or using free blocks and the real time clock via p31025. Note When the multi-zone control is activated, the analog inputs are newly interconnected as sources for the setpoint and actual value of the technology controller (see table).
Functions 7.9 Application-specific functions Note Please note that when multi-zone control is activated, any BiCo interconnections present for analog inputs and for the technology controller's setpoint and actual value are cancelled and interconnected with the links defined in the factory. When you deactivate multi-zone control, the associated BiCo interconnections are cancelled. Example The temperature in a large office is measured at three points and transferred to the inverter using analog inputs.
Functions 7.9 Application-specific functions p0757.3 = 0 / p0758.3 = 0 Set lower value of the scaling characteristic p0759.3 = 100 / p0760.3 = 100 Set upper value of the scaling characteristic p31026.2 = 755.1 Temperature actual value 3 via temperature sensor with current output (0 mA … 20 mA) via analog input 1 p0756.1 = 2 Select analog input type (current input 0 … 20 mA) p0757.1 = 0 / p0758.1 = 0 Set lower value of the scaling characteristic (0 mA ≙ 0 °C) p0759.1 = 20 / p0760.
Functions 7.9 Application-specific functions 7.9.12 Cascade control The cascade control function is used in applications that require between one and four motors to be run at the same time depending on load, so that e.g. highly variable pressure ratios or flow volumes can be corrected.
Functions 7.9 Application-specific functions To avoid frequent activation/deactivation of the uncontrolled motors, a time can be specified in p2377 which must have elapsed before a further motor can be activated/deactivated. After the time set in p2377 has elapsed, a further motor will be activated immediately if the PID deviation is greater than the value set in p2376.
Functions 7.9 Application-specific functions Controlling the activation and deactivation of motors Use p2371 to determine the order of activation/deactivation for the individual external motors.
Functions 7.9 Application-specific functions Parameters to set and activate the cascade control: p0730 = r2379.0 Signal source for digital output 0 Control external motor 1 via DO 0 p0731 = r2379.1 Signal source for digital output 1 Control external motor 2 via DO 1 p0732 = r2379.
Functions 7.9 Application-specific functions 7.9.13 Bypass If the bypass is controlled by a higher-level control, the control must lock the contactors so they cannot switch on at the same time. If controlled by inverter, the digital outputs are used to activate two contactors via which the motor is powered. The inverter is provided with contactor position feedback via the digital inputs. This is evaluated. If using direct connection logic (high level = ON), both contactors should be NO contacts.
Functions 7.9 Application-specific functions When changing over to inverter operation, initially contactor K2 must be opened and after the de-excitation time, contactor K1 is closed. The inverter then captures the rotating motor and the motor is operated on the inverter. Bypass function when activating via a control signal (p1267.0 = 1) The status of the bypass contactors is evaluated when the inverter is switched on. If the automatic restart function is active (p1210 = 4) and an ON command (r0054.
Functions 7.9 Application-specific functions Bypass function is dependent on the speed (p1267.1 = 1) With this function, changeover to line operation is realized corresponding to the following diagram, if the setpoint lies above the bypass threshold. If the setpoint falls below the bypass threshold, the inverter captures the motor and the motor is fed from the inverter.
Functions 7.9 Application-specific functions General properties of the bypass function ● y ● Contactors K1 and K2 must be mutually interlocked so that they cannot close at the same time. Shutdown behavior in bypass operation ● If the motor is in the bypass mode, it cannot be shutdown with OFF 1. The motor coasts down after an OFF2 or OFF3.
Functions 7.9 Application-specific functions 7.9.14 Energy-saving mode The energy-saving mode is mainly used for pumps and fans. Typical applications include pressure and temperature controls. In the energy-saving mode, the inverter stops and starts the motor depending on the system conditions. The energy-saving mode can be activated via the technology controller (without external commands via terminals or bus interface) and via an external setpoint input.
Functions 7.9 Application-specific functions In the energy-saving mode, the motor is shut down; however, the speed setpoint and/or the technology controller deviation are/is monitored. ● For an external setpoint input (without technology controller) the speed setpoint is monitored and the motor is switched-on again as soon as the setpoint increases above the restart speed. The restart speed is calculated as follows: Restart speed = P1080 + p2390 + p2393.
Functions 7.9 Application-specific functions Energy-saving mode with setpoint input using the internal technology controller In this operating mode, the technology controller must be activated as the setpoint source (p2200) and used as the main setpoint (p2251). The function can be operated both with and without boost.
Functions 7.9 Application-specific functions Energy-saving mode with external setpoint input In this operating mode, the setpoint is specified by an external source (e.g. a temperature sensor); the technology setpoint can be used here as a supplementary setpoint.

Every digital and analog signal available via BICO technology can be routed to the appropriate inputs of the free function blocks. The outputs of the free function blocks are also interconnected to other functions using BICO technology.

8 Service and maintenance 8.1 Overview of replacing converter components In the event of a permanent function fault, you can replace the converter's Power Module or Control Unit independently of one another. In the following cases, you may immediately switch on the motor again after the replacement. Replacing the Power Module Replacement: Replacing the Control Unit with external backup of the settings, e.g.
Service and maintenance 8.2 Replacing the Control Unit 8.2 Replacing the Control Unit WARNING 230 V AC can be connected via the relay outputs DO 0 and DO 2 of the Control Unit. These terminals can carry 230 V AC independent of the voltage condition of the Power Module. Therefore please observe appropriate safety measures when working on the inverter. After commissioning has been completed, we recommend that you back up your settings on an external storage medium, e.g.
Service and maintenance 8.2 Replacing the Control Unit Procedure for replacing a Control Unit without a memory card ● Disconnect the line voltage of the Power Module and (if installed) the external 24 V supply or the voltage for the relay outputs DO 0 and DO 2 of the Control Unit. ● Remove the signal cables of the Control Unit. ● Remove the defective CU from the Power Module. ● Plug the new CU on to the Power Module. ● Reconnect the signal cables of the Control Unit. ● Connect up the line voltage again.
Service and maintenance 8.3 Replacing the Power Module 8.3 Replacing the Power Module Procedure for replacing a Power Module ● Disconnect the Power Module from the line supply. ● If being used, switch off the 24 V supply of the Control Unit. DANGER Risk of electrical shock! Hazardous voltage is still present for up to 5 minutes after the power supply has been switched off.
Alarms, faults and system messages 9 The converter has the following diagnostic types: ● LED The LED at the front of the converter immediately informs you about the most important converter states right at the converter. ● Alarms and faults The converter signals alarms and faults via the fieldbus, the terminal strip (when appropriately set), on a connected operator panel or STARTER. Alarms and faults have a unique number. If the converter no longer responds Due to faulty parameter settings, e.g.
