Procedure For Switching Off An Uncontrolled Motor - Siemens SINAMICS G120XA Operating Instructions Manual

Advanced commissioning
6.5 Technology controller
Figure 6-53

Procedure for switching off an uncontrolled motor:

1. The speed-controlled motor turns with minimum speed p1080.
2. The control deviation of the technology controller is less than -p2373.
3. Time p2375 has expired.
The converter accelerates the speed-controlled motor with ramp-up time p1120 to the
activation/deactivation speed p2378. Until the activation/deactivation speed p2378 is
attained, the converter deactivates the technology controller temporarily.
4. After shutdown delay p2386, the converter disconnects an uncontrolled motor.
