Page 18: Power Connection
Transistor Servo-Drive TV6.2 Adjustments - Power connection Note: The order of the connections to the connector numbers or screw terminals is ob- ligatory. All further advices are non-obligatory. The input and output conductors may be altered or supplemented in accor- dance with the electrical standards.
Page 19 4 Adjustments Adjustments Ballast circuit ballast resistor (continuous power = 15W) is installed. It is activated at 200V dc. The ballast circuitry has an over-voltage watchdog. In case of over-voltage, the device is internally blocked, a short-circuit is signalled, and the ‘ready’ contact (BTB) is opened.
Page 20 Transistor Servo-Drive TV6.2 The transistor power sections have an internal watchdog and protect themsel - Under fault-free conditions the BTB-relay will be controlled. The BTB-relay will switch off in case of the following faults: auxiliary voltage supply: +15V, -15V power section: fuse failure, buffer circuitry voltage too high permanent short-circuit or circuit to earth...
Page 21 4 Adjustments Adjustments - Enable The control advise is provided as general information and it is not obligatory. The local regulations and the connection and operating instructions must be adhered to. Connectors X1: 2ac to X1: 32c Terminals X1: 1 to X1:16 X2 : 17 to X2 : 26 When connecting X1:32c (X1:1) to X1:30c (X1:2) or applying a voltage superior to +10V, the command value and the speed controller (RVU) will be enabled...
Page 22 Transistor Servo-Drive TV6.2 Adjustments - Command value The command value input X1:26c (X1:4) is dimensioned for a voltage command value of ±10V . The command value is generated by using the internal voltage supplies of +10V across X1:28c (X1:3) and -10V across X1:24c (X1:5) or by applying a com- mand value voltage from a PLC or CNC.
Page 23: Command Value
4 Adjustments Command value A correction value of max. ±10V can be applied across the connector X1:32a (X1:17). The input resistance is 100 kΩ . If the polarity is the same as that of X1:4 (command value), the correction vol- tage will be added.
Page 24: Current Limiting
Transistor Servo-Drive TV6.2 The current limiting can be adjusted internally by means of the po- tentiometers P6 (I ) and P5 (I ) from 0 and 200% type current (rated cur - max1 max 2 rent). In this case the switches S6:K2 and S6:K3 must be closed (ON). For external current limiting adjustments or control the switches S6:K2 and S6:K3 must be open (OFF).
Page 25: Actual Value
4 Adjustments The actual value is connected as tacho signal or as armature voltage signal with an internal bridge (switch S6:K4 ON). The quality of the actual value signal determines the control range and the control precision. The best results can be achieved through the use of dc tacho generators.
Page 26 Transistor Servo-Drive TV6.2 In case there is no fault signal from the internal power section watchdogs, the signal contact BTB (drive ready) is closed. The contact signals to the PLC or CNC that the motor controller is ready for operation. The outputs have regenerating fuses.
Page 27 4 Adjustments An ammeter for the armature current can be connected to the terminals X1:26a (X2:20) and X1:18a (X2:24). The output voltage is ±5V for ±200% type current. The output resistance is 1kΩ . The command value input can be switched as a differential input or as an input amplifier with reference to point zero, depending on how the switch S2:K2 is switched.
Page 28 Transistor Servo-Drive TV6.2 he proportional and integration components of the speed controller are adjus- ted by means of two 16-position binary switches and the amplification potentio- meter P3 (Xp) . When replacing the control electronics the adjusted values can be taken over. Adjustment P-component by means of the binary switch S4 Switch S4 Position...
Page 29: Armature Voltage Control
4 Adjustments Tacho control In order to control the speed by means of the tacho actual value, the switch S6:K4 must be open. The polarity of the tacho signal at X1: 22c (X1:6) and the command value input (X1: 6) must be opposite. The rough adjustment of the actual value is achie- ved by means of the binary switch S9 .
Page 30 Transistor Servo-Drive TV6.2 Adjustments Control values The adjusted control values can be measured at the connector X4:3 by means of an oscilloscope. The reference command value at the connector X4:1 is transferred to channel 1 and the control output at X4:3 to channel 2 of the oscil- loscope.
Page 31: Peak Current
4 Adjustments The effect of the actual value differentiation can be measured at the connec- tor no. X4:7 by means of an oscilloscope. When the motor is connected and enabled a command value jump of 50% is set and the actual value response is examined. Example: high amplification low amplification The switches S6:K2 and S2:K3 must be closed.
Page 32: Commutation Limit
Transistor Servo-Drive TV6.2 The commutation limit must be checked when using a dc motor with a permanent excitation (no field) and iron core. The motor data sheets show the limiting curve of the permissible motor current dependent on the speed. The maximum torque of the motors, which corresponds to the maximum current, is 3 to 6 times the value of the continuous torque.
