Siemens SINAMICS G120C Operating Instructions Manual page 311

Procedure
1. Switch on the motor with a setpoint of a few revolutions per minute.
2. Check whether the motor rotates smoothly.
3. If the motor does not rotate smoothly, or even remains stationary, increase the voltage boost
p1310 until the motor runs smoothly.
4. Accelerate the motor with the maximum load.
5. Check that the motor follows the setpoint.
6. If necessary, increase the voltage boost p1311 until the motor accelerates without problem.
In applications with a high break loose torque, you must also increase parameter p1312 in
order to achieve a satisfactory motor response.
You have set the voltage boost.
