2.1 .l 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 CO38 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 controller is connected to mains voltage.
3 Basic settings 3.1 Operating mode The controllers of the 8600 series offer different interfaces. From these you tan select each one for control and programming. Controller interfaces for control and programming: Terminals The terminals are exclusively used to control the controller. Keyp’ad The five keys and the plain text display tan be used mainly for programming. A control via the keypad is also possible.
3.1 .l Controller enable Depending on the selected operating mode (Cool) different procedures are necessary to enable the controller. - Terminal control, i.e. CO01 = -O-, -2-, -4l l 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, CO40 serves as a display: l CO40 = -0- means controller is inhibited. l CO40 = -l- means controller is enabled. Control via keypad, i.e.
_- In case of control via the keypad or the LECOM interface, quick stop tan also be (de-)activated via C042. Parameter (Factory setting is printed in bold) -oQuick stop not active/deactivate quick stop -lQuick stop activelactivate quick stop Acceptance SH + PRG If you want to deactivate quick stop: . l - Apply a voltage between 13 and 30V across terminals 21 or 22 (CCW rotation). If you have set CO42 to -l- via the keypad or one of the L.
3.2 Configuration Using code CO05 you tan determine the internal control structure and the use of the setpoint and act. value 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 setpoint (O...+iOV for CW rotating field, O...lOV for CCW rotating field). A closed-loop Speed control is to be used, for which a DC tacho serves as act. value. A setpoint 2 is not used.

3.4 Features of setpoint 1 An analog entry of setpoint 1 is possible via input Xl/terminal 8, otherwise it is entered via the keypad or the LECOM interfaces. This depends on the selected operating mode (Cool). The configuration determines whether the input is unipolar, bipolar, or independently of the operating mode, a digital frequency input. With terminal control you tan read setpoint 1 under code C046.
3.4.2 Digital frequency input - With the corresponding configuration (CO05) you tan use the g-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.
Features of setpoint 2 3.5 Setpoint 2 tan only be provided via the differential input Xl/terminals 1,2, independently of the selected operating mode (Cool). Its value tan only be displayed in per cent under code co49. - Setpoint 2 is processed first by a special ramp generator, before it is added to setpoint 1 .The ramp times of the ramp generator are set separately via C220 and C221.
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 CO25 the corresponding analog input. Adjust the Signal gain such that the desired setpoint is obtained. For the adjustment of the act. value see pages 75 and 77.
The Io control, also referred to a “magnetizing-current control” allows a considerabiy higher torque compared to the normal V/fcharacteristic control, without the motor being overexcited when the drive is deloaded. 3.7.1 V/f-characteristic control You have to Change from Io control (factory setiing) to V/fcharacteristic control if you want to supply several drives with different loads or rated power from one controller.
-. Vif-rated frequency With the V/f-rated frequency, the slope of the characteristic is set. The value to be entered under CO1 5 results from the motor ratings: V / f -- rated frequency = 400 v VNmotor . rated motor frequency The values for the most common motor types tan be obtained from the following table. Motor data rated voltage 380V 4oov I t k - 4 1 5 v 415v 440v 460V 4aov 4aov rated frequency 50Hz V/f-rated frequency (C015) 52.6Hz 50Hz 50Hz 60Hz 60Hz 50.OHz 48.2Hz 57.8Hz 54.
3.7.2 IO contra1 “Io 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 IO control tan be used especially for Single drives. lt 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 tan use Code CO10 to program a minimum output frequency. This changes the influence of the analog setpoint to setpoint 1 in the factory-set configuration CO05 = -0- (not for other configurations).

Under CO12 and CO1 3, the ramp generator for the main setpoint (Setpoint l/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 CO1 1.
4 - Closed-loop speed control For a number of applications, the accuracy which tan 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 tan select a configuration with a Pl controller. The appropriate configuration depends on the way of setpoint input and the actual value input you want to use.

The large setting ranges of the control Parameters also allow the control of an application datum if this depends on the drive Speed.
4.4 Adjustment of the act. value gain If you use an incremental encoder for Speed control and you have entered the encoder constant as described under 4.2. (see page Fehler! Textmarke nicht definiert.) an adjustment of the act. value gain is not necessary. For tacho act. value, a gain adjustment is normally required. 4.4.1 Automatic adjustment To adjust the act. value gain you tan activate an automatic adjustment under C029.
Calculate the required act. value gain according to the following equation: l --. Required gain = active gain l measured Speed desired Speed Enter the calculated value after selecting the suitable act. value input (C025) under C027. 4.5 Setting of the controller Parameters With the setting of the Controller Parameters, you adapt the Pl Controller to the drive. This adjustment is necessary after the autoadjustment as well as after the manual adjustment.
4.6 Additional functions For special applications, you tan use a variety of additional functions: - Input integral action component = 0 Using this function, the integral action component (I-component) of the PI controller tan be reset to zero. You tan activate this additional function via one of the freely assignable digital inputs. Fur further information about programming of the freely assignable inputs see page 81. This function is e.g.
5 Programming of the freely assignable inputs and Outputs Most of the inputs and outputs of the frequency controller are freely assignable via their own Codes, i.e. they tan be especially assigned to the required Signals. Furthermore, these Signals tan be adjusted in the best possible way by setting facilities. In factory setting, these inputs are already assigned to certain functions.

If you want to re-assign an input, the previous programming is lost. A function tan only be assigned to one input.
5.2.3 DGinjection brake If you want to brake the drive fast, but do not want to use a brake chopper, you tan activate the DC-injection brake via the suitable input. Please note that the braking time may vary each time. Before you tan use the DGinjection brake, set the brake voltage under C036. The brake voltage also determines the brake current and therefore the brake torque. If the current limitation is activated by the brake current, reduce the brake voltage.
5.2.4 JOG frequencies If you need cer-tain fixed settings as main setpoint, you tan cal1 programmed setpoints via the JOG frequencies. These JOG frequencies replace setpoint 1. Please note that in configurations with additional setpoints, the setpoint 2 is set to zero, as long as a JOG frequency is active.
Enabling JOG frequencies 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. E4 = first input, E5 = second input). With terminal control, the active JOG frequency is displayed under co4.5. With control via keypad or LECOM interfaces activate the JOG frequencies.
5.2.5 Additional acceleration and deceleration times For the ramp generator of the main setpoint (setpoint l/JOG frequency) you tan cal1 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 ClOO, one pair of acceleration and deceleration times is selected.

5.2.6 Ramp generator stop While the drive is accelerated via the ramp generator of the main setpoint, you tan hold the ramp generator using the assigned digital input, e.g. to wait for cet-tain actions before accelerating. With terminal control you tan read under Cl31 whether the ramp generator is stopped or not. With control via the keypad or the LECOM interfaces the ramp generator (main setpoint) is stopped and enabled again under C131.
- 5.2.9 You tan 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 controller. Programming of Parameter sets To program several Parameter Sets, the following Steps are requ ired: l l l Enter all settings for one application. Select code CO03 and save your Parameter set for example under -l- (Parameter set 1). Enter all settings for another application (e.g. different material).
With control and programming via keypad or LECOM interfaces you tan Start the loading of a Parameter set under CO02. Under CO02 you tan also load the factory setting.

5.4.2 Maximum current reached, Imax When the output current has reached the maximum current limit which is programmed under C022, the red LED on the keypad is illuminated and the assigned output sends a message. In case of overload, the output frequency is automatically reduced (Vif reduction) to prevent a further rising of the motor current. You tan also use the maximum current limit, e.g. to accelerate the drive at the set maximum current limit.
The status of “pulse inhibit” is indicated by the illuminated yellow LED on the keypad and the permanently assigned digital output terminal 45. Pulse inhibit means that the output of the frequency controller is inhibited. Possible Causes are: l l l Controller inhibit Fault indication TRIP Under-/Overvoltage (see page 99) If you need the permanently assigned output terminal 45 with inverted polarity you must use a freely assignable output and set the polarity as required. 5.4.7 Act.

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 tan 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 Chopper frequency The controllers of the 8600 series offer the feature to adapt the chopper frequency of the controller to the noise and smooth running requirements of the motor. By increasing the chopper frequency you tan generally reduce the motor noises which are generated by the pulsating output voltage. By reducing the chopper frequency the smooth running in the low frequency range is often improved.
6.1 .l Automatic chopper frequency reduction - If you want to operate the frequency controller with 4 kHz (Cl43 = -2- to -6-) or a higher chopper frequency, but also require an improved smooth running with low Speeds, you tan activate an automatic chopper frequency reduction, restricted to this range. For this, enter the output frequency under C143, below which the chopper frequency is to be reduced automatically to 2 kHz.
6.4 S-shaped ramp generator characteristic For the ramp generator of the main setpoint you tan select two different characteristics under Cl 34: l linear characteristic for all constant accelerations l S-shaped characteristic for all jerk-free accelerations.

The controller divides the Speed setpoint by the actual winding diameter. The Speed setpoint tan either be provided by a JOG value, an analog input terminal X8, or by the digital frequency input X5. When changing the operating mode, also the operating unit or one of the LECOM interfaces are available. This procedure allows a Pilot synchronization of the circumferential Speed of the bale to the line Speed. That means that the field frequency is high for small diameters and low for large diameters. 9.2.

9.8 Adjustment of the dancer-Position controller 9.8.1 Setpoint Provision - The act. value Signal of the dancer-Position controller is set via the terminals 3 and 4. The input Signal is displayed as percentage under code CO51 with Cl72 = -O-. In this case IOV = 100%. The input Signal is resolved with 12 bits (iOV/4096 = 2.44mV) plus sign. For the input of the dancer-Position setpoint, the dancer must be adjusted normally to the desired operating Position.
9.8.2 Winding or unwinding Winding from above or from below The command “unwinding from above” or “unwinding from below” is given by the CW/CCW reversal (reversing command e.g. via terminals 21 and 22). Unwinding from above or from below For unwinding, the sign for the influence of the dancer-Position Controller must be inverted. This achieved by the following: l Change the polarity of the voltage supply for the dancer Potentiometer. l Invert the act.
9.9.1 Overlay of Position controller The function “overlay of position controller” is necessary for the Start of the winding-up process with the dancer in an extreme Position. The full effect of the dancer-Position controller could lead to extreme operating conditions. Therefore the slow overlay of the output Signal is necessary when starting the winding-up process. The function “overlay of Position controller” tan be achieved via freely assignable terminals, keypad, or the serial interface.
9.9.2 Conversion of modulation of dancer-Position controller to field frequency Code Cl 91 is a calibration factor which is used to convert the modulation of the dancer-Position controller into a frequency. The unit of this code is mHz/%. That means that the user assigns the corresponding field frequency with 1% modulation of the dancerPosition controller. Example: With Cl 91 = 290 mHz/%, 100% modulation of the dancer-Position controller corresponds to a field frequency of 29 Hz.
To activate the diameter compensator the threshold which is to be set under C94 must be decreased so that the dancer-Position controller tan be activated. With the setting of Cl 94 = 100 % (factory setting) the diameter compensator is disconnected from the dancer-Position controller. - 9.10.1 Reset of the diameter compensator The diameter compensator tan be reset (e.g. after finishing the winding process) via a freely assignable digital input, the operating unit, or the LECOM interfaces.

9.12 Application: Tandem winder 9.13.1 Digital frequency output The digital frequency output is required e.g. for a master Slave coupling (two motors are connected by friction to one winder shaft). For master-Slave couplings it is important that, in case of Speed reduction of the master, e.g. due to the current limiting function Imax,, the Slave Passes the same field frequency to the motor as the master. A frequency Signal which is proportional to the field frequency tan be supplied to terminal X9.
9.13 -_ Application: Loop control with Speed adaption Among others, a loop control is required for the transport of material by means of two conveyor belts. The slack which occurs between the two conveyor belts is kept constant by the loop control. To ac:tivate the loop control the code Cl 89 must be set to -0- but only with activated controller inhibit. Usually the field frequency Pilot control is not used for the loop control. Therefore e.g. 2V has to be entered under Cl80 as diameter setpoint.

For this, the torque setpoint is entered via an analog Signal input which is permanently compared with the torque supplied to the motor shaft. If the torque setpoint exceeds the act. value torque, the field frequency and thus the output voltage is reduced until setpoint and act. value are identical. If the act.

The quality of the control behaviour is set via the Vp-gain factor CO77 and the adjustment time Tn C078. Therefore the field frequency is reduced with a reduction of the torque setpoint, until the ratio between Speed and torque is stable. If the ,torque setpoint is increased, the field frequency increases. Here, the field frequency input via terminal 8 or via the digital frequency input or via code CO46 is used to limit the maximum field frequency.

12.3.5 Baud rate (LECOMI) Under code Cl 25 you tan enter different baud rates. Code Cl25 Parameter Meaning 9600 baud 4 8 0 0 baud 2 4 0 0 baud 1200 baud 4% -l-2-3- 12.3.6 History of reset faults Under Cl 61 to Cl 68 you tan read the last eight faults stored. The last reset fault is displayed in Cl 61. 12.3.7 Code bank (LECOMI) With version 1 .O of the LECOM A/B protocol, Codes up to C255 tan be processed. To resch also higher numbers with this Version, the accessible range tan be changed by code C249.
12.3.9 High resolution data Under Codes C380 to C382 you tan enter very precise setpoint and act. value with a resolution of 14 bit plus sign. Setpoint 1: Setpoint scaled to the maximum frequency. The value of 214 corresponds to 100% of the maximum field frequency. The inforrnation is identical with that under C046, with the differente that you tan read the controller value directly thus excluding conversion errors.

Service 1 Fault indication When a fault occurs, the Operation of the frequency controller is immediately interrupted and the Signal “ready” is removed. The fault is displayed automatically under C067. The fault indication is flashing as long as the fault has not been reset. Fault reset: Press SH + PRG or activate the input TRIP reset. Reset fault indications are stored. They tan be displayed again by selected code CO67 and pressing the DOWN-key in the Parameter level.
