Caution: The safety functionality is only completely guaranteed after this time has expired.
Notice: This parameter is overwritten by the copy function of the safety functions integrated in the drive.
If this value is reduced, this can have a negative impact on the actual value acquisition and plausibility check – and
result in Safety message C30711 with the message value 1041 or 1042.
Note: This parameter is only effective for encoderless actual value sensing (p9506/p9306 = 1, 3).
Description: Sets the filter time for smoothing the actual value with sensorless actual value sensing.
Notice: This parameter is overwritten by the copy function of the safety functions integrated in the drive.
A longer filter time results in a longer response time.
Description: Sets the minimum current for encoderless actual value sensing in reference to 10 mA (i.e. when 1 % = 10 mA).
- The value must be increased if C30711 has occurred with message value 1042.
- The value must be decreased if C30711 has occurred with message value 1041.
For synchronous motors, the following condition must be fulfilled:
|p0305 x p9783| >= p9388 x 1.2
Dependency: Refer to: r9785
Refer to: C30711
Notice: This parameter is overwritten by the copy function of the safety functions integrated in the drive.
If this percentage value is reduced excessively, then this can result in a safety message and an inaccurate actual
value.
Description: Sets the acceleration limit to filter velocity fluctuations.
If this percentage value is increased, when accelerating, velocity peaks that do not reflect the real velocity charac-
teristic can occur.
