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_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 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
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.
p9389 SI Motion actual value sensing sensorless accel. limit (P2) / ActVal sl a_lim P2
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
10.00 [%]
Description: Sets the acceleration limit to filter velocity fluctuations.
If this percentage value is increased, when accelerating, velocity peaks that do not reflect the real velocity charac-
teristic can occur.
If this value is decreased, and this dampens the velocity peaks when accelerating.
- The value must be increased if C30711 with message value 1043 has occurred.
- The value must be lowered if acceleration procedures have led to an excessive Safety actual velocity.
Dependency: Refer to: r9784
Refer to: C30711
Notice: This parameter is overwritten by the copy function of the safety functions integrated in the drive.
r9398[0...1] SI Motion actual checksum SI parameters (processor 2) / SI Mtn act CRC P2
CU240D-2_DP_F Access level: 3
CU240D-2_PN_F
Can be changed: -
CU250D-2_DP_F
Units group: -
CU250D-2_PN_F
Min
-
Description: Displays the checksum over the checked Safety Integrated parameters of the motion monitoring functions (actual
checksum) on processor 2.
Index: [0] = Checksum over SI parameters for motion monitoring
[1] = Checksum over SI parameters with hardware reference
Dependency: Refer to: p9399
