Meaning
Control unit terminal
p9620[0]
Sets the signal source for the STO, SBC and SS1 functions of the Control
Unit.
This is only relevant if a basic function via terminal is set in the options.
Otherwise, the input field is deactivated.
SS1 delay time
p9652
Sets the delay time of the pulse cancellation in seconds for the function "Safe
Stop 1" (SS1) on the Control Unit to brake along the OFF3 down ramp
(p1135).
Braking response for SS1
p9653
Select a predefined braking response below the input field "SS1 delay time".
Parameter p9653 is preassigned depending on the selected braking re‐
sponse.
F-DI input filter
p9651
Setting the debounce time in ms for the Failsafe Digital Inputs to control STO/
SBC/SS1.
Simultaneity monitoring
p9650
Sets the discrepancy time in ms for the switchover of the safety-relevant
inputs (SGE) on the Control Unit.
STOP F -> STOP A delay time
p9658
Sets the transition time from STOP F to STOP A in ms on the Control Unit.
Forced checking procedure of the switch-off
signal paths
p9659
Sets the time interval in hours for carrying out the forced checking procedure
and testing the switch-off signal paths.
Switch-off signal path test required
r9773.31
To evaluate whether the switch-off signal paths must be tested, the status of
r9773.31 “Switch-off signal path must be tested" can be interconnected with
a parameter via the BICO editor.
