Description: Sets the tolerance for the cross-check of the actual position between processor 1 and processor 2.
Dependency: Refer to: p9542
Refer to: C01711
Notice: This parameter is overwritten by the copy function of the safety functions integrated in the drive.
Description: Sets the filter time for the SSM feedback signal to detect standstill.
Notice: This parameter is overwritten by the copy function of the safety functions integrated in the drive.
Note: The filter time is effective only if the function is enabled (p9301.16 = p9501.16 = 1).
The parameter is included in the crosswise data comparison of the two monitoring channels.
SSM: Safe Speed Monitor (safety-relevant feedback signal from the velocity monitoring)
Description: Sets the velocity limit for the SSM feedback signal to detect standstill (n < nx).
When this limit value is undershot, the signal "SSM feedback signal active" is set.
Dependency: Refer to: p9546
Caution: The following applies for p9306 = 3:
The "SAM" function is switched out if the selected threshold value is undershot.
Notice: This parameter is overwritten by the copy function of the safety functions integrated in the drive.
Note: SAM: Safe Acceleration Monitor (safe acceleration monitoring)
SSM: Safe Speed Monitor (safety-relevant feedback signal from the velocity monitoring)
Description: Sets the velocity hysteresis for the SSM feedback signal to detect standstill (n < nx).
Dependency: Refer to: C01711
Notice: This parameter is overwritten by the copy function of the safety functions integrated in the drive.
Note: The velocity hysteresis is effective only if the function is enabled (p9301.16 = p9501.16 = 1).
The parameter is included in the crosswise data comparison of the two monitoring channels.
SSM: Safe Speed Monitor (safety-relevant feedback signal from the velocity monitoring)
