If value = -1:
- for synchronous motors, the calculation is automatically made with the value 4.
- for induction motors, the calculation is automatically made with a value of 0 (if the code number of the power unit
p0201[0] < 14000, otherwise with a value of 2).
p9586 SI Motion actual value sensing sensorless delay time (P1) / ActVal sl t_del P1
CU240D-2_DP_F Access level: 3
CU240D-2_PN_F
Can be changed: C(95)
CU250D-2_DP_F
Units group: -
CU250D-2_PN_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: C01711
Caution: The safety functionality is only completely guaranteed after this time has expired.
Notice: If this value is reduced, this can have a negative impact on the actual value acquisition and plausibility check – and
result in Safety message C01711 with the message value 1041 or 1042.
Note: This parameter is only effective for encoderless actual value sensing (p9506/p9306 = 1, 3).
p9587 SI Motion actual value sensing sensorless filter time (P1) / Actv sl t_filt P1
CU240D-2_DP_F Access level: 4
CU240D-2_PN_F
Can be changed: C(95)
CU250D-2_DP_F
Units group: -
CU250D-2_PN_F
Min
0.00 [ms]
Description: Sets the filter time for smoothing the actual value with sensorless actual value sensing.
Notice: A longer filter time results in a longer response time.
p9588 SI Motion actual value sensing sensorless minimum current (P1) / ActVal sl I_min P1
CU240D-2_DP_F Access level: 3
CU240D-2_PN_F
Can be changed: C(95)
CU250D-2_DP_F
Units group: -
CU250D-2_PN_F
Min
0.00 [%]
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 C01711 has occurred with message value 1042.
- The value must be decreased if C01711 has occurred with message value 1041.
For synchronous motors, the following condition must be fulfilled:
|p0305 x p9783| >= p9588 x 1.2
Dependency: Refer to: r9785
Refer to: C01711
Notice: If this percentage value is reduced excessively, then this can result in a safety message and an inaccurate actual
value.
