Possible cause 1 (during commissioning or parameter modification)
The tolerance value for the monitoring function is not the same on the two monitoring channels.
Possible cause 2 (during active operation)
The limit values are based on the current actual value (r9713). If the safe actual values on the two monitoring chan-
nels do not match, the limit values, which have been set at a defined interval, will also be different (i.e. corresponding
to fault value 3). This can be ascertained by checking the safe actual positions.
44: Position actual value (r9713) + limit value for SLS1 (p9531[0]/p9331[0]) * Safety monitoring clock cycle
45: Position actual value (r9713) - limit value for SLS1 (p9531[0]/p9331[0]) * Safety monitoring clock cycle
46: Position actual value (r9713) + limit value for SLS2 (p9531[1]/p9331[1]) * Safety monitoring clock cycle
