SINAMICS G120C
152 List Manual (LH13), 04/2014, A5E33840768B AA
Description: Display and connector output for the actual smoothed speed actual value of the speed control.
Description: Sets the smoothing time for the actual speed of the speed controller for encoderless closed-loop speed control.
Note: The smoothing must be increased if there is gear backlash. For longer smoothing times, the integral time of the
speed controller must also be increased (e.g. using p0340 = 4).
Description: Sets the P gain for encoderless operation for the speed controller.
Note: The product p0341 x p0342 is taken into account when automatically calculating the speed controller (p0340 = 1, 3,
4).
Description: Set the integral time for encoderless operation for the speed controller.
Note: The integral component is stopped if the complete controller output or the sum of controller output and torque pre-
control reach the torque limit.
Description: Sets the signal source for the torque setting value when starting up with motor holding brake.
Dependency: .
Note: The setting of the integral output of the speed controller begins after magnetizing (see p0346, r0056 bit 4) and ends
at the end of the brake control opening time p1216. A setting value of zero means that no setting procedure will take
place.
If p1351 is used as a signal source for the torque setting value, the percentage value is interpreted in relation to the
rated torque (p2003).
