SINAMICS G120 Control Units CU240S, Edition 05/2007
Description: Displays maximum torque of the regenerative current component.
Description: Displays total upper torque limitation.
Description: Displays total lower torque limitation.
Description: Defines fixed value of flux setpoint in [%] relative to rated motor flux.
Note: If P1570 > 100 %, the flux setpoint rises according to the load from 100 % to the value of P1570 between idling and
nominal load.
Description: Sets dynamic voltage headroom for vector control.
Description: Sets the efficiency optimization for closed-loop vector control in [%]. When optimizing the efficiency, the flux set-
point is adapted as a function of the load.
Note: If P1580 > 0, the dynamics for speed control (P1470, P1472) are restricted to prevent vibration.
When no load is applied, a value of 100 % produces full flux reduction (i.e. to 50 % of rated motor flux).
When using optimization, it is necessary to increase the smoothing time of the flux setpoint (P1582).
