p9386 SI Motion actual value sensing sensorless delay time (P2) / ActVal sl t_del P2
CU240D-2_DP_F Access level: 3
CU240D-2_PN_F
Can be changed: C(95)
CU250D-2_PN_F
Unit group: -
CU250D-2_DP_F
Min
5.00 [ms]
Description: Sets the delay time to evaluate the encoderless actual value sensing after the pulses have been enabled.
The value must be greater than or equal to the motor magnetizing time (p0346).
Dependency: Refer to: C30711
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).
The set time is rounded internally to an integer multiple of the monitoring clock cycle.
p9387 SI Motion actual value sensing sensorless filter time (P2) / Actv sl t_filt P2
CU240D-2_DP_F Access level: 3
CU240D-2_PN_F
Can be changed: C(95)
CU250D-2_PN_F
Unit group: -
CU250D-2_DP_F
Min
0.00 [µs]
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.
p9388 SI Motion actual value sensing minimum current (P2) / ActVal sl I_min P2
CU240D-2_DP_F Access level: 3
CU240D-2_PN_F
Can be changed: C(95)
CU250D-2_PN_F

CU250D-2_DP_F
Min
0.00 [%]
Description: Sets the minimum current for encoderless actual value sensing referred to 1 A (i.e. 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
Recommendation: If required, the correct value of the motor minimum current should be determined by making the appropriate
measurements.
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.
