Parameters
List of Parameters
p9383 SI Motion brake ramp monitoring time (processor 2) / SI Mtn rp t_mon P2
CU240E-2 DP F Access level: 3
CU240E-2 F
Can be changed: C(95)
Units group: -
Min
500.00 [ms]
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.
p9386 SI Motion delay time of the evaluation sensorless (processor 2) / SI Mtn t_del SL MM
CU240E-2 DP F Access level: 3
CU240E-2 F
Can be changed: C(95)
Units group: -
Min
5.00 [ms]
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
p9387 SI Motion encoderless act val sensing filter time (processor 2) / SI Mtn SL filt P2
CU240E-2 DP F Access level: 4
CU240E-2 F
Can be changed: C(95)
Units group: -
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.
p9388 SI Motion actual value sensing minimum current (processor 2) / SI Mtn SL I_min P2
CU240E-2 DP F Access level: 3
CU240E-2 F
Can be changed: C(95)
Units group: -
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 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.
