p9588 SI Motion actual value sensing sensorless minimum current (CU) / ActVal sl I_min CU
VECTOR_G Can be changed: C2(95)
Data type: FloatingPoint32
P-Group: Safety Integrated
Not for motor type: -
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 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
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: C01711
Notice: If this percentage value is reduced excessively, then this can result in a safety message and an inaccurate actual
value.
Note: This parameter is only effective for encoderless actual value sensing (p9506/p9306 = 1, 3).
p9589 SI Motion act. value sensing sensorless acceleration limit (CU) / ActVal sl a_lim CU
VECTOR_G Can be changed: C2(95)
Data type: FloatingPoint32
P-Group: Safety Integrated
Not for motor type: -
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
characteristic can occur.
If this value is decreased, and this dampens the velocity peaks when accelerating.
- the value must be increased if C01711 with message value 1043 has occurred.
- the value must be lowered if acceleration procedures have led to an excessive Safety actual velocity.
Recommendation: The setting of this parameter depends on the motor and closed-loop control, and must be newly determined for each
configuration.
To do this, a measurement should be performed while the actual value jumps, and the limit in r9785[0] must be set so
low using p9589, so that it is exceeded by the value in r9785[1] a maximum of four times per second. The actual
value correction filter intervenes at this instant in time. The step is no longer so drastic.
Dependency: Refer to: r9784
Refer to: C01711
Note: This parameter is only effective for encoderless actual value sensing (p9506/p9306 = 1, 3).
For p9589 = maximum value, the filter is deactivated.
Diagnostics parameter p9784 must be used to correctly set this parameter.
