Siemens SINAMICS G120C DP User Manual

Function description
If you use sensorless vector control with a pulling load, then the following settings are required:
• Set the following parameters:
• When opening the motor holding brake, enter a speed setpoint>0.
For speed setpoint = 0, and with the motor holding brake open, the load drops because the
induction motor rotates with the slip frequency as a result of the pulling load.
• Set the ramp-up and ramp-down times≤10s in the ramp-function generator.
• If, in quick commissioning, you have selected application class Dynamic Drive Control then
set p0502=1 (technological application: dynamic starting or reversing).
