Error message
Meaning of the error message Measures
Main
index
Sub
index
Cause: Upper and lower switch supply voltage
not simultaneously activated
(discrepancy time exceeded)
Error in control / external circuitry of
safety module.
Error in safety module.
Action:
Check circuitry of the safety module
– are the inputs STO-A and STO-B
switched off on two channels and
simultaneously?
Replace safety module if you
suspect it is faulty.
2
Safety function: Failure of driver
supply with active PWM
activation
Cause: Failure of driver supply voltage with
active PWM.
Action:
The safe status was requested with
power output stage enabled. Check
integration into the safety-orientated
interface.
3
FSM: Rotational speed limits in
basic device overlap
Cause: Basic device reports error if the
currently requested direction of
movement is not possible because the
safety module has blocked the setpoint
value in this direction.
Error may occur in connection with the
SSFx safe speed functions if an
asymmetrical speed window is used
where one limit is set to zero. In this
case, the error occurs when the basic
device moves in the blocked direction
in the Positioning mode.
Action:
Check application and change if
necessary.
