4 Installation 4.1 Mechanical installation • • These frequency inverters must only be used as built-in units. Install the inverter vertically with the terminal strips at the bottom. • Allow a free space of 100 mm at the top and bottom. For the units 8612 ... 8615 this free space is also required at both sides. Ensure unimpeded ventilation of cooling air.
4.2 Electrical installation • The drive controllers are equipped with electrostatically endangered components. The service and maintenance personnel must be electrostatically discharged before working at the units. They can discharge by touching the PE fastening screw or another earthed metallic surface in the control cabinet. • All control inputs and outputs of the inverter are mains-isolated. The mains isolation has a basic insulation.
4.2.1 Motor protection The units do not have a full motor protection. For monitoring the motor temperature PTCs or thermal contacts can be used. The connection possibilities are shown on page 28. When using group drives, a motor protection relay is required for each motor. When using motors which do not have a suitable insulation for inverter operation: - Connect motor filters for protection (see page 43). Please contact your motor manufacturer.

5.4 Screenings Cable screenings increase the noise immunity of the drive system and reduce the interfering radiation. The power and control terminals of the inverters are noise immune without screened cables up to severity class 4 to IEC 801-4. Burst of 4kV on the power terminals and 2kV on the control terminals are permissible. Screenings are only required when you want to operate the inverter in environments, where severity class 4 is not sufficient.
6 Accessories Accessories are not included in the scope of supply. 6.1 Brake resistors In the generator mode, e.g. when decelerating the drive, the machine returns energy to the DC bus of the controller. If large inertias are braked and/or short deceleration times are set, the DC bus voltage may exceed its maximum permissible value. In the case of overvoltage in the DC bus, the controller sets pulse inhibit and indicates "overvoltage ".

7.3 Connecting elements for optical fibre cables−LECOM-LI Lenze offer a series of specially designed connection accessories for the inverters, in order to use the fibre optic communication bus. The accessories included adapters with optical transmitter and receiver, a distributor and power pack. Due to the optical fibre cables, data transmission with a very high immunity to interferences is possible. 7.
8 Initial switch-on Which settings are necessary for the drive to operate? After mains connection the inverter is ready to operate after approx. 0.5 seconds. The frequency inverters are factory-set such that a four-pole standard motor with 400V rated voltage and 50Hz according to the combinations in section 3.1 can be operated without further settings. In case of motor ratings according to section 3.2 or 3.3, page 17ff, it is necessary to increase the permanent output power accordingly.

2 Basic control operations Programming of the frequency inverter enables the drive to be adapted to your application. The possible settings are arranged in codes, which are numbered in ascending order and start with the letter "C". Each code provides one parameter which can be selected according to the application. Parameters can be absolute or relative values of a physical unit (e.g. 50Hz or 50% related to fdmax) or numerical codes giving certain status information (e.g.
The arrow position marks whether you are in the code or in the parameter level. → C O u 0 t 5 p 0 u t f r 0 e . q 0 u e H n z c . e 0 n H y z c y Press, until C011 is displayed → m C a 0 x 1 . 1 f r e 5 q 0 u Press PRG to change to the parameter level m C a 0 x 1 . 1 f → r e 5 q 0 u . e 0 n H y z c . e 0 n H y z c Press, until 60 Hz is displayed m C a 0 x 1 . 1 f → r e 6 q 0 u The maximum field frequency of 60Hz is now set and is accepted immediately.
2.1.1 Parameter setting by two codes Some parameters are set by two codes. A preselection code is used to select the parameter which is to be changed. The parameter is then changed by another code. For example, to set the JOG frequency JOG3, first set the preselection code C038 to -3- and then set the desired frequency for JOG3 via code C039. 2.2 Save parameters After the acceptance, new parameters are saved in the RAM until the inverter is connected to mains voltage.
3 Basic settings 3.1 Operating mode The inverters of the 8600 series offer different interfaces. From these you can select each one for control and programming. Controller interfaces for control and programming: Terminals The terminals are exclusively used to control the inverter. Keypad The five keys and the plain text display can be used mainly for programming. A control via the keypad is also possible.
3.1.1 Controller enable Depending on the selected operating mode (C001) different procedures are necessary to enable the controller. Terminal control, i.e. C001 = -0-, -2-, -4- • Apply a voltage between 13 and 30V across terminal 28. • If you have pressed the STP key, enable the controller with SH + STP in addition. In case of terminal control, C040 serves as a display: • C040 = -0- means controller is inhibited. • C040 = -1- means controller is enabled. Control via keypad, i.e.
In case of control via the keypad or the LECOM interface, quick stop can also be (de-)activated via C042. Code C042 Parameter -0-1- Meaning Deactivate quick stop Activate quick stop Acceptance SH + PRG If you want to deactivate quick stop: • Apply a voltage between 13 and 30V across terminals 21 or 22 (CCW rotation). • If you have set C042 to -1- via the keypad or one of the LECOM interfaces, deactivate quick stop in addition by setting C042 to -0-.
3.2 Configuration Using code C005 you can determine the internal control structure and the use of the set-value and feedback inputs.
3.2.1 Example of how to select a configuration The direction of rotation of the motor in a system is to be determined by the sign of the analog set-value (0...+10V for CW rotating field, 0...10V for CCW rotating field). A closed-loop speed control is to be used, for which a DC tacho serves as feedback. A set-value 2 is not used.

3.4 Features of set-value 1 An analog entry of set-value 1 is possible via input X1/terminal 8, otherwise it is entered via the keypad or the LECOM interfaces. This depends on the selected operating mode (C001). The configuration determines whether the input is unipolar, bipolar, or independently of the operating mode, a digital frequency input. With terminal control you can read set-value 1 under code C046.
3.4.2 Digital frequency input With the corresponding configuration (C005) you can use the 9-pole Sub-D socket X5 or X8 as digital frequency input, where two complementary signals shifted by 90° are provided. If you use an HTL-encoder, it is sufficient to provide only the signals A and B. The inputs A\ and B\ must then be bridged using +Vcc (pin 4). The maximum input frequency is 300 kHz for TTL encoders and 100 kHz for HTL encoders.
3.5 Features of set-value 2 Set-value 2 can only be provided via the differential input X1/terminals 1,2, independently of the selected operating mode (C001). Its value can only be displayed in per cent under code C049. Set-value 2 is processed first by a special ramp generator, before it is added to set-value 1.The ramp times of the ramp generator are set separately via C220 and C221. Code C220 C221 Parameter 5.0s 0.0 to 990s 5.0s 0.
Gain Set the signal gain after the offset adjustment. First apply that signal to which you want to adjust the internal display (see offset). Then select under C025 the corresponding analog input. Adjust the signal gain such that the desired set-value is obtained. For the adjustment of the feedback input see pages 73 and 75. Code C025 Parameter -1-2-4-1000...+1000 mV (factory setting) 1.000 -2.500...+2.500 C026 C027 3.
3.7.1 V/f characteristic control You have to change from I0 control (factory setting) to V/f characteristic control if you want to supply several drives with different loads or rated power from one inverter. Also for pump and blower drives to be operated with a square characteristic, a V/f characteristic control is required. V/f characteristic With V/f characteristic control the output voltage is controlled according to the characteristic set via C014 and C016.
Voltage boost Vmin In the low speed range, the obtained torque is determined largely by the set voltage boost. If you set Vmin (C016), make sure that the motor cannot be destroyed by overheat. Experience tells that self-ventilated standard asynchronous machines of insulation class B can be operated in a frequency range up to 25Hz only for a short time with rated current. Therefore proceed as follows: • The motor should be operated in idle running. • Provide a set-value of 4 to 5 Hz.
3.7.2 I0 control "I0 control" is especially suited for machines with a large breakaway torque. Compared to the V/f characteristic control it provides considerably larger torques up to the motor rated point. The advantages of I0 control can be used especially for single drives. It is also possible for group drives, provided that the motors are of the same type and have the same load, e.g. two identical drives, which drive a common shaft from two sides.
3.8 Minimum field frequency fdmin You can use code C010 to program a minimum output frequency. This changes the influence of the analog set-value to set-value 1 in the factory-set configuration C005 = -0- (not for other configurations). set-value 1 fdmax fdmin 0 100% analog set-value X1/term. 8 For set-value inputs via keypad or LECOM interfaces, the fdmin setting is not effective. Code C010 3.9 Parameter 0.0Hz 0.0...
3.10 Acceleration and deceleration times Tir, Tif The ramp generators (main set-value, set-value 2) are programmed using the acceleration and deceleration times. Under C012 and C013, the ramp generator for the main set-value (Setvalue 1/JOG frequency) receives its standard setting. The acceleration and deceleration times refer to a change of the field frequency from 0 to the maximum field frequency set under C011.
4 Closed-loop speed control For a number of applications, the accuracy which can be obtained with open-loop speed control is often not sufficient. To avoid a speed reduction which occurs when an asynchronous motor is loaded, you can select a configuration with a PI controller. The appropriate configuration depends on the way of set-value input and the actual value input you want to use.
4.3 Frequency pilot control For applications where the feedback signal is directly proportional to the speed of the drive (actual speed) it is advantageous to pilotcontrol the output frequency with the set-value or feedback. The influence of the PI controller can be limited such that only the maximum machine slip to be expected is controlled.
Closed-loop control without pilot control, closed-loop control of an application datum The PI controller is normally used for the speed control of the connected motor. The large setting ranges of the control parameters also allow the control of an application datum if this depends on the drive speed. For this it may be necessary to switch off the frequency pilot control and to set the PI controller to 100% influence.
4.4.2 Manual adjustment If, for technical reasons, the above described automatic adjustment in idle running is not possible or too inaccurate, you can measure the motor speed by hand and calculate the required feedback gain. Proceed as follows: • Activate the closed-loop speed control (C005) with pilot control of the output frequency by the controller reference (C238 = -1-). • If possible, enter 100% set-value. If the set-value is smaller, the obtainable adjustment result is normally less precise.
4.6 Additional functions For special applications, you can use a variety of additional functions: ,QSXW LQWHJUDO DFWLRQ FRPSRQHQW Using this function, the integral action component (I-component) of the PI controller can be reset to zero. You can activate this additional function via one of the freely assignable digital inputs. Fur further information about programming of the freely assignable inputs see page 78. This function is e.g.
5 Programming of the freely assignable inputs and outputs Most of the inputs and outputs of the frequency inverter are freely assignable via their own codes, i.e. they can be especially assigned to the required signals. Furthermore, these signals can be adjusted in the best possible way by setting facilities. In factory setting, these inputs are already assigned to certain functions. 5.
Except for the functions "Enable JOG frequencies", "Enable additional acceleration and decleration times" and "Select parameter set", every function can only be assigned to one terminal. If you want to re-assign an input, the previous programming is lost. A function can only be assigned to one input. A double assignment is not possible. 5.2 Functions of the freely assignable digital inputs 5.2.1 Set TRIP The inverter receives a TRIP message via the assigned input.
Extended operation of the DC injection braking may cause the motor to overheat! Code C036 C107 Parameter 0.0% 0.0...40% 999s 0.0...999s Meaning Voltage for DC injection braking Acceptance ON-LINE Holding time for DC injection braking 999s = Holding time not limited ON-LINE With terminal control C048 serves as display whether the DC injection braking is active or not. With control via the keypad or the LECOM interfaces the DC injection braking is (de-)activated via C048.
Assignment of the digital inputs The number of required inputs for the function "Enable JOG frequency" depends on the amount of the required JOG frequencies. JOG frequencies Number of required JOG frequencies 1 2...3 4...7 8...15 Number of required inputs at least 1 at least 2 at least 3 4 A maximum of four inputs can be assigned to this function. For the assignment of the inputs see the notes on page 78.
5.2.5 Additional acceleration and deceleration times For the ramp generator of the main set-value (set-value 1/JOG frequency) you can call additonal acceleration and deceleration times from the memory, e.g. to change the acceleration speed of the drive as from a certain speed. Programming of additional acceleration and deceleration times The ramp times are set in two steps, under C100, one pair of acceleration and deceleration times is selected.
Enabling the additional acceleration and deceleration times With terminal control activate the assigned digital inputs according to the table below. The input with the smallest number is the first input, the input with the next highest number is the second input, etc. (e.g. E7 = first input, E8 = second input).
5.2.6 Ramp generator stop While the drive is accelerated via the ramp generator of the main set-value, you can hold the ramp generator using the assigned digital input, e.g. to wait for certain actions before accelerating. With terminal control you can read under C131 whether the ramp generator is stopped or not. With control via the keypad or the LECOM interfaces the ramp generator (main set-value) is stopped and enabled again under C131.
5.2.10. Select parameter set, Load parameter set You can store up to four different parameter sets, for example when you want to process different material with one machine or if you want to run different motors with one inverter. Programming of parameter sets To program several parameter sets, the following steps are required: • Enter all settings for one application. • Select code C003 and save your parameter set for example under -1- (parameter set 1). • Enter all settings for another application (e.g.
With control and programming via keypad or LECOM interfaces you can start the loading of a parameter set under C002. Under C002 you can also load the factory setting. Code C002 5.
Every function can only be assigned to one output, including the relay output. If you want to re-assign an output, the previous programming is lost. A function which is already assigned to an output, can only be assigned to another terminal or the relay output, if the previously used output has been assigned to another function. 5.4 Functions of the freely assignable digital outputs 5.4.
5.4.4 Fault indication TRIP A fault is indicated via the permanently assigned digital output terminal 41 and - in factory setting - via the relay output. If you need the output terminal 41 with reverse polarity, you have to use a freely assignable output and set the polarity as required. Before, the relay output must be assigned to another function. 5.4.5 Ready, RDY The status "ready" is indicated approximately 0.
5.4.9 Flying restart circuit active If you have activated the flying restart circuit, the assigned output indicates when the flying restart circuit is active. For further information about the flying restart circuit see page 95. 5.4.10 Process control active, process step active If you use the process control, the assigned outputs indicate when the process control or individual steps are active. For further information about the process control see page 94. 5.
5.6 Digital frequency output X9 (Option) The connection of drives via digital frequency allows a simple and precise control of multi-motor systems. The digital frequency output X9 can be used here as digital frequency encoder, e.g. for parallel or slave drives.
6 Additional open-loop and closed-loop control functions 6.1 Chopping frequency The inverters of the 8600 series offer the feature to adapt the chopping frequency of the inverter to the noise and smooth running requirements of the motor. By increasing the chopping frequency you can generally reduce the motor noises which are generated by the pulsating output voltage. By reducing the chopping frequency the smooth running in the low frequency range is often improved.
6.1.1 Automatic chopping frequency reduction If you want to operate the frequency inverter with 4 kHz (C143 = -2- to -6-) or a higher chopping frequency, but also require an improved smooth running with low speeds, you can activate an automatic chopping frequency reduction, restricted to this range. For this, enter the output frequency under C143, below which the chopping frequency is to be reduced automatically to 2 kHz.
6.4 S-shaped ramp generator characteristic For the ramp generator of the main set-value you can select two different characteristics under C134: • linear characteristic for all constant accelerations • S-shaped characteristic for all jerk-free accelerations. Code C134 6.
6.6 Process control By programming a process control you can enter fixed speed profiles which are processed automatically. The process control can consist of a maximum of eight process steps. Each step consists of a set-value (C211), an acceleration or a deceleration time (C212) and the duration of the step (C213). The number of the step to be processed next is entered via C214. Program the process control as follows: • Under C210, select the process step which you want to program.
Activating the process control With terminal control you can activate the process control via one of the freely assignable digital inputs. With control via keypad or the LECOM interfaces the process control is (de-)activated under C044. Code C044* Parameter -0-1- Meaning Finish process control Process control active Acceptance SH + PRG * extended code set The process control always starts with step 1.
Rated motor power By entering the rated motor power (C081), the flying restart circuit is adapted to the motor. If the rated motor power is programmed correctly, the obtainable flying restart accuracy shows the best results. Code C081* Parameter -4-5-6-7-8-9-10-11-12-13-14-15-16-17-18-19-20-21-22-23-24- Meaning 0.25kW 0.37kW 0.55kW 0.75kW 1.1kW 1.50kW 2.20kW 3.0kW 4.0kW 5.5kW 7.5kW 11.0kW 15.0kW 18.5kW 22.0kW 30.0kW 37.0kW 45.0kW 55.0kW 75.0kW 90.0kW Acceptance SH + PRG * extended code set 6.
7 Overload protections 7.1 Overload protection of the frequency inverter (I⋅t monitoring) The frequency inverters have an output current monitoring to protect them against overload. You can adapt this protection to the maximum ambient temperature to be expected. The lower the max. ambient temperature, the higher the limit of the permissible continuous output current. The permissible continuous output power rises the same way.
7.2.2 I²⋅t monitoring The motor temperature can be calculated and monitored by the inverter. Set the motor monitoring as follows: • Enter the motor frame size under code C086 together with the kind of ventilation. • Set C088 to the rated motor current. • Select the motor protection under code C119 (I²⋅t monitoring). • Activate the motor protection under code C120. If the motor current permanently exceeds the shown characteristic, fault OC6 is indicated and the controller is inhibited.
8 Display functions 8.1 Code set All codes in the inverter are arranged in different code sets. With factory setting, the standard code set is activated. It contains all codes which are required for the most common applications. By selecting the extended code set under code C000, the display of the keypad also shows those codes which are suitable for special applications. There is also a service code set which is not accessible in general.
8.3 Display of actual values Under codes C050 to C054 you can read different actual values. Code C050 C051 Act. value Output frequency Feedback of PI controller C052 C053 C054 Motor voltage DC bus voltage Motor current 8.4 Display absolute in Hz with C172 = -0-: related to fdmax with C172 = -1-: absolute in Hz absolute in Veff absolute in V absolute in Aeff Switch-on display If you connect the inverter to the mains, the output frequency is shown as the first display (C050).

10 Serial interfaces The frequency inverters can communicate with superimposed hosts (PLC and PC) and the Lenze operating units 323 and 324 via the serial interfaces LECOM1 and LECOM2. 10.1 LECOM1 interface X6 The LECOM1 interface (X6 connector) can be used to connect devices to the RS232C standard (LECOM-A) or to the RS485 standard (LECOM-B). The interface is suitable for parameter setting, monitoring, diagnosis, and simple controls.
10.2 LECOM2 interface (option) For more sophisticated applications, you can use a field bus connecting interface. In the programming section, this interface is called LECOM2. For the bus system Interbus-S the connecting interface 2110 with the DRIVECOM profile is available. For the bus system PROFIBUS the connecting module 2130 is also available with DRIVECOM profile. The modules 2110 and 2130 are available are options and can be integrated into the inverter (see also page 50). 10.

Code C125 Parameter -0-1-2-3- Meaning 9600 baud 4800 baud 2400 baud 1200 baud 10.3.6 History of reset faults Under C161 to C168 you can read the last eight faults stored. The last reset fault is displayed in C161. 10.3.7 Code bank (LECOM1) With version 1.0 of the LECOM A/B protocol, codes up to C255 can be processed. To reach also higher numbers with this version, the accessible range can be changed by code C249.
10.3.9 High resolution data Under codes C380 to C382 you can enter very precise set-value and feedback with a resolution of 14 bit plus sign. Set-value 1: Set-value scaled to the maximum frequency. The value of 214 corresponds to 100% of the maximum field frequency. The information is identical with that under C046, with the difference that you can read the controller value directly thus excluding conversion errors.
