Description: Sets the tolerance for the crosswise data comparison of the actual position between processors 1 and 2.
Dependency: Refer to: C01711
Note: For a linear axis, the tolerance is internally limited to 10 mm.
For a "linear axis with rotating motor" and standard setting of p9520, p9521 and p9522, the standard setting of
p9542 corresponds to a position tolerance of 36 ° on the motor side.
Description: Sets the filter time for the SSM feedback signal to detect standstill.
Note: The filter time is effective only if the function is enabled (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.
Caution: The following applies for p9506 = 3:
The "SAM" function is switched out if the selected threshold value is undershot.
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
