SINAMICS G120 Control Units CU240S, Edition 05/2007
Description: Configuration for speed control.
Note: P1400 Bit 00 = 1:
Automatic gain adaption of speed controller (P1460 resp. P1470) is enabled. In the area of field weakening the gain
is reduced in dependence on flux.
P1400 Bit01 = 1:
The integrator of the speed controller is frozen if Sensorless Vector Control (SLVC) is selected and the control is
switched from closed-loop to open-loop operation.
Advantage:
The correct amount of slip compensation is calculated and applied to the open-loop function for a motor under load.
Description: Displays status of motor control, which can be used to diagnose inverter status.
Note: See P0052 (CO/BO: Status word 1)
Description: Displays setpoint of speed controller.
Description: Sets time constant of PT1 filter to smooth actual speed of speed controller.
