Commissioning in torque control mode (T)

Step Description Remarks
1 Switch off the mains supply.

2 Power off the servo drive and connect it to The digital signals CWL, CCWL and EMGS must be

SMART) with the signal cable.
Refer to "Standard application wirings (factory setting)
(Page 73)" and "Connection examples with PLCs
(Page 77)".

3 Power on the servo drive.
4 Switch to the torque control mode by setting Refer to "Compound controls (Page 125)".
p29003=3.
5 Restart the servo drive to apply the settings of
the torque control mode.

6 Configure necessary digital input signals by The factory settings are:
setting the following parameters:
• p29301[3]: 1 (SON)
• p29301[3]: DI1 • p29302[3]: 2 (RESET)
• p29302[3]: DI2 • p29303[3]: 3 (CWL)
• p29303[3]: DI3 • p29304[3]: 4 (CCWL)
• p29304[3]: DI4 • p29305[3]: 12 (CWE)
• p29305[3]: DI5 • p29306[3]: 13 (CCWE)
• p29306[3]: DI6 • p29307[3]: 18 (TSET)
• p29307[3]: DI7 • p29308[3]: 19 (SLIM1)
• p29308[3]: DI8 Refer to "Digital inputs/outputs (DIs/DOs) (Page 61)".

7 Select torque setpoint by configuring the digital • TSET = low level (0): external analog torque

torque) for analog torque setpoint corresponding
to 10 V by setting parameter p29041[0].
9 If the fixed torque setpoint is used, input your Refer to "Torque control with fixed torque setpoint

by setting p29002=2.
Refer to "Actual status display (Page 112)".

Result: Thus the Connection of servo motor with computer and SINAMICS V90 servo drive was successfully
established and Performed speed control and Torque control of motor.
