Status information
Status Meaning
SS1 active
r9722.1
Status signals for the safety motion monitoring functions integrated in the
drive on monitoring channel 1.
STO active
r9722.0
Velocity resolution
Load side
r9732[0]
Displays the safe velocity resolution (load side). Velocity limits that are
specified - or parameter changes for velocities below this threshold - have no
effect.
Settings
Setting Meaning
Delay time STOP F -> STOP B
p9555
Sets the transition time from STOP F to STOP B
The set time is internally rounded off to an integer multiple of the monitoring
clock cycle.
SS1 monitoring
p9507.3=0
Selects the stop response, which is initiated when selecting function SS1 or
activating a STOP B.
● SS1 with OFF3
SS1 with OFF3 braking response integrated in the drive
● SS1E external stop
Stop to be externally initiated. Braking monitoring (SBR, SAM) is deac‐
tivated.
Delay time SS1/STOP B -> STO active
p9556
Sets the delay time for STOP A to STOP B.
The set time is internally rounded off to an integer multiple of the monitoring
clock cycle.
Shutdown speed SS1
p9560
(only for SS1 with OFF3)
Sets the shutdown velocity for activating STO. "Standstill" is assumed below
this velocity, and for STOP B / SS1, an STO is selected.
In the case of encoderless motion monitoring functions, this parameter must
be > 0 (10 is recommended).
Note: The shutdown velocity has no effect for a value = 0.
