p9586 SI Motion delay time of the evaluation sensorless (CU) / SI Mtn t_del SL CU
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. Shortening the time can result in Alarm 1711 with fault value 1041 or1042.
Dependency: Refer to: C01711
Notice: Reducing this value can adversely affect the actual value sensing and the plausibility check.
When the value is increased, this results in a longer evaluation delay.
Note: This parameter is only effective for encoderless actual value sensing (p9306/p9506 = 1).
p9587 SI Motion encoderless act val sensing filter time (processor 1) / SI Mtn SL filt P1
CU240E-2 DP F Access level: 4
CU240E-2 F
Can be changed: C(95)
Units group: -
Min
0.00 [ms]
Description: Sets the filter time for smoothing the actual value with sensorless actual value sensing.
p9588 SI Motion act val sensing sensorless min current (processor 1) / SI Mtn SL I_min P1
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 C01711 has occurred with message value 1042.
- The value must be decreased if C01711 has occurred with message value 1041.
Dependency: Refer to: C01711
Notice: Reducing this percentage value can adversely affect actual value sensing.
p9589 SI Motion voltage tolerance acceleration (processor 1) / SI Mtn U tol P1
CU240E-2 DP F Access level: 3
CU240E-2 F
Can be changed: C(95)
Units group: -
Min
10.00 [%]
Description: Sets the voltage tolerance for suppressing acceleration peaks.
Increasing this percentage value means that voltage peaks will need to have a higher amplitude during acceleration
procedures if they are not to affect actual value sensing.
- The value must be increased if C01711 has occurred with message value 1043.
- The value must be lowered if acceleration procedures have led to an excessive Safety actual velocity.
Dependency: Refer to: C01711
