The setting specifying whether the analog input is a voltage input (10 V) or current input (20 mA) must be made via P0756 and in addition using the DIP switches on the Control Unit housing.

Functions 5.6 Setpoint preparation 5.6 Setpoint preparation Overview of setpoint calculation The setpoint calculation 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 5-8 5.6.
Functions 5.6 Setpoint preparation 5.6.2 Parameterizing the ramp-function generator Parameterizing the ramp-function generator The ramp-function generator in the setpoint channel limits the speed of setpoint changes. This causes the motor to accelerate and decelerate more smoothly, thereby protecting the mechanical components of the driven machine. Ramp-up/down time The ramp-up and ramp-down times of the ramp-function generator can be set independently of each other.
Functions 5.6 Setpoint preparation Rounding Acceleration can be "smoothed" further by means of rounding. The jerk occurring when the motor starts and when it begins to decelerate can be reduced independently of each other. Rounding can be used to lengthen the motor acceleration/deceleration times. The rampup/down time parameterized in the ramp-function generator is exceeded. Rounding does not affect the ramp-down time in the event of a quick stop (OFF3).
Functions 5.7 Closed-loop control 5.7 Closed-loop control Overview There are two different open-loop and closed-loop control techniques for inverters used with synchronous and induction motors. ● Closed-loop control with V/f-characteristic (called V/f control) ● Field-oriented control technology (called vector control) 5.7.1 V/f control 5.7.1.1 Typical applications for V/f control 0 V/f control is perfectly suitable for almost any application in which the speed of induction motors is to be changed.
Functions 5.7 Closed-loop control 5.7.1.2 0 V/f control with linear characteristic Table 5- 30 Setting the control type Parameter Description P0003 = 2 Extended access P1300 = 0 Control type: V/f control with linear characteristic Optimizing the starting characteristics for a high break loose torque and brief overload The inverter can provide a higher voltage in the lower speed range and when accelerating.
Functions 5.7 Closed-loop control 5.7.1.3 0 V/f control with parabolic characteristic Note V/f control with a parabolic characteristic must not be used in applications in which a high torque is required at low speeds. Table 5- 32 5.7.1.
Functions 5.7 Closed-loop control 5.7.2 Vector control 5.7.2.1 Typical applications for vector control The vector control can be used to control (closed-loop) the speed and the torque of a motor. 0 Vector control is used in many cases without directly measuring the motor speed. This closed-loop control is known as sensorless vector control. The vector control is also used with a speed encoder in special applications.
Functions 5.7 Closed-loop control 5.7.2.2 0 Commissioning vector control Vector control with and without speed encoder requires careful commissioning and therefore must only be performed by commissioning engineers that are experienced in handling this type of control. Steps when commissioning the vector control 1. Carry out quick commissioning (P0010 = 1) In order to ensure that the vector control functions perfectly, it is absolutely imperative that the motor data is entered correctly 2.
Functions 5.7 Closed-loop control 5.7.2.3 0 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 5.7 Closed-loop control 5.7.2.4 Using a speed encoder Higher accuracy by using a speed encoder 0 A speed encoder increases the accuracy of the speed and the torque of the vector control for speeds below approx. 10% of the rated motor frequency. Commissioning the speed encoder A speed encoder requires the following commissioning steps: 1. Connect the speed encoder (see below). 2. Set the encoder voltage using the DIP switches on the CU (see below). 3.
Functions 5.7 Closed-loop control CAUTION Use a shielded cable to connect the speed encoder. The shield must not be interrupted by terminal points between the encoder and inverter. Setting the encoder voltage The encoder voltage is set using the DIP switches at the front of the CU. If you use either a BOP or a PC Connection Kit, you must remove this module in order to be able to access the switches.

If the motor is in regenerative mode, i.e.
Functions 5.8 Protection functions 5.8.3 Limiting the maximum DC link voltage How does the motor generate overvoltage? An induction motor can operate as a generator if it is driven by the connected load, In this case, the motor converts mechanical energy into electrical energy. The motor feeds the regenerative energy back to the inverter. As a consequence, the DC link voltage is increased.
Functions 5.8 Protection functions 5.8.4 Load torque monitoring (system protection) Applications with load torque monitoring In many applications, it is advisable to monitor the motor torque: ● Applications in which the mechanical connection between the motor and load may be interrupted (e.g. if the drive belt in fan or conveyor belt systems tears). ● Applications that are to be protected against overload or locking (e.g. extruders or mixers).

Functions 5.10 Technological functions WARNING Secure loads held by the brake! Since this procedure cancels the "Brake active" signal which, in turn, causes the brake to be forced open, the user must ensure that, even when the motor has been powered-down, all loads held by the brake are secured before the signal is canceled.

Functions 5.10 Technological functions Note The higher the search rate (P1203), the longer the search time. A lower search rate shortens the search time. The "flying restart" function decelerates the motor slightly. The smaller the drive torque, the more the drive is decelerated. The "flying restart" function should not be activated for motors in group drives due to the different coasting characteristics of the individual motors. 5.10.2.
Functions 5.10 Technological functions WARNING When the "automatic restart" function is active (P1210 > 1), a motor can restart automatically once the power has been restored. This is particularly critical if it is incorrectly assumed that the motors have been shut down after a long power failure. For this reason, death, serious injury, or considerable material damage can occur if personnel enters the working area of motors in this condition. Commissioning the automatic restart 1.

For a fixed ramp-down type, the number of revolutions that a motor requires to reach a standstill depends on the speed of the motor at the instant of the switch-off.

The following diagram shows the structure and sequence of parameter channel and process data (PZD).
Functions 5.11 Operation in fieldbus systems Parameter ID (PKE) and parameter index (IND) The parameter ID (PKE) is always a 16 bit value.

Functions 5.11 Operation in fieldbus systems Parameter value (PWE) When communication takes place via the USS, the number of PWEs can vary. One PWE is required for 16 bit values. If 32 bit values are exchanged, two PWEs are required. Note U8 data types are transferred as U16, whereby the upper byte is zero. U8 fields, therefore, require one PWE for each index. A parameter channel for 3 words is a typical data telegram for exchanging 16 bit data or alarm messages.

Functions 5.12 Safety functions 5.12 Safety functions 5.12.1 Overview Functional safety Machine components operated by electrical drives are intrinsically hazardous. If a drive is incorrectly used or acts in an unexpected manner in the event of a malfunction, not only can this damage the machine but it can also cause severe injury or death. Functional safety reduces this risk of accidents caused by machines to an acceptable residual risk.
Functions 5.12 Safety functions Permissible control modes for using fail-safe functions When the above-mentioned conditions are fulfilled, the fail-safe functions can be used for both V/f control and vector control. Restrictions regarding SLS and SS1 CAUTION Safety functions SS1 and SLS must not be used if the motor, after it has been switched-off, can still be accelerated by the mechanical elements of the connected machine component. Whether or not a mechanical brake is installed is irrelevant.
Functions 5.12 Safety functions Examples of how the safety functions can be applied Table 5- 90 Application examples for safety functions Description of problem Suitable Solution safety function When the EMERGENCY STOP button is STO pressed, a stationary motor must not start unintentionally. Control the inverter via terminals using an Emergency-Stop button. A central EMERGENCY STOP button is designed to prevent more than one drive from starting unintentionally.
Functions 5.12 Safety functions 5.12.2 Connecting-up the fail-safe inputs Connecting sensors to fail-safe inputs The fail-safe inputs of the inverter are designed for connecting electromechanical sensors with two NC contacts. It is not possible to directly connect sensors with two NO contacts and antivalent contacts (1 NO contact and 1 NC contact).

Functions 5.12 Safety functions 5.12.3 Restoring safety-related parameters to the factory setting Before starting to commission the safety functions, you should know whether the safetyrelevant parameters of the inverter have already been changed. If you do not precisely know the setting of the safety-relevant parameters, then reset these parameters to the factory setting.
Functions 5.12 Safety functions 5.12.4 Controlling the safety functions via PROFIsafe The safety functions can either be controlled via digital inputs or via the fieldbus i.e. PROFIBUS or PROFINET with the fail-safe PROFIsafe profile. Examples for connecting an inverter to a fail-safe SIMATIC control via PROFIsafe is provided in the Internet under the following URL: ● PROFIBUS control of the safety functions (STO, SLS and SS1) of a SINAMICS G120 with an S7 300-F CPU (http://support.automation.siemens.
Functions 5.12 Safety functions 4. Select the "Enables" tab. None of the fail-safe inputs are activated in the factory setting, i.e. no input is assigned to a safety function 5. Click on the button on the lower edge of the STARTER screen and enter the safety password. The default password is '12345'. The inverter outputs alarm A1698 to signal that safety settings are currently being changed. Further, the following LEDs flash on the Control Unit: RDY, ES, STO, SS1, and SLS. 6.
Functions 5.12 Safety functions Debouncing and filtering the signals from the fail-safe input As soon as a fail-safe input has been assigned to a safety function, the inverter checks the consistency of the input signal. Consistent signals at both terminals always assume the same signal state (high or low). Reasons for inconsistent input signals With electromechanical sensors (e.g. EMERGENCY STOP buttons or door switches), the contacts may bounce briefly at the moment switching takes place.
Functions 5.12 Safety functions 5.12.6 Settings for the "STO" function You can make two settings for the STO safety function. Testing the shutdown paths Shutdown paths are electronic circuits of the inverter used to disconnect a motor in a safetyrelevant fashion. The shutdown paths must be checked regularly to ensure that the fail-safe inverter complies with certification requirements. The shutdown paths are always checked after the inverter has been switched on.

The inverter outputs alarm A1698 to signal that safety settings are currently being changed. Further, the following LEDs flash on the Control Unit: RDY, ES, STO, SS1 and SLS 6. Deactivate the regular shutdown path test when exiting the STO function. Test periods to monitor the shutdown paths A timer monitors the execution of the shutdown path test.
Functions 5.12 Safety functions 5.12.7 Settings of the SS1, SLS and SBC safety functions Always parameterize the fail-safe functions using the STARTER PC tool. Parameterizing failsafe functions using the BOP is always very time consuming due to the fact that parameters must be set twice. The safety functions are parameterized according to the following schematic: 1. Go online with STARTER, open the screen with the safety functions and click on the button 2.
Functions 5.12 Safety functions Safety function SLS (Safely Limited Speed) The SLS safety function can be operated in three different modes. Depending on the mode, the inverter behavior differs when the SLS safety function is activated.
