p9653 SI Safe Stop 1 drive-based braking response
Sets the braking response integrated in the drive for the "Safe Stop 1" (SS1) func‐
tion.
Value: 0: SS1 with OFF3
Value 1: SS1E external stop
Note:
SS1: Safe Stop 1 (safe stop 1, corresponds to stop Category 1 according to
EN60204)
SS1E: Safe Stop 1 external (safe stop 1 with external stop)
SS1E requires the externally initiated stop for conformance with stop Category 1.
This parameter is used to to switch over from SS1 to SS1E and to deactivate the
braking response (drive-based) of function SS1 (time controlled) of the Basic
Functions.
Unit: Default value:
- 0
p9658 SI transition time STOP F to STOP A (Control Unit)
Sets the transition time from STOP F to STOP A on the Control Unit.

For a crosswise data comparison between p9658 and p9858, a difference of one
safety monitoring clock cycle is tolerated.
The parameterized time is internally rounded-off to an integer multiple of the mon‐
itoring clock cycle.
STOP F: Defect in a monitoring channel (error in the CDC)
STOP A: Pulse deletion via safety switch-off signal path
Unit: Default value:
ms 0
p9659 SI forced checking procedure timer
Sets the time interval to carry out the dynamic update and to test the safety switch-
off signal paths (forced checking procedure).
Within the parameterized time, STO must have been deselected at least once. The
monitoring time is reset at every STO deselection.
