2.2 List of parameters
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.
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 C30711 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 p9389, 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: C30711
Notice:
This parameter is overwritten by the copy function of the safety functions integrated in the drive.
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
