Description: Sets the monitoring time to define the brake ramp.
The rate of rise of the brake ramp depends upon p9381 (reference value) and p9383 (monitoring time).
Dependency: Refer to: p9381, p9382
Notice: This parameter is overwritten by the copy function of the safety functions integrated in the drive.
Description: Sets the evaluation delay for encoderless actual value sensing after pulse enable.
The value should be greater than or equal to the motor magnetizing time.
Dependency: Refer to: C01711
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.
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.
Dependency: Refer to: C30711
Notice: This parameter is overwritten by the copy function of the safety functions integrated in the drive.
Reducing this percentage value can adversely affect actual value sensing.
