The safety function in the master PLC must detect the following events in order to uncover dangerous errors and, in
case of error, actuate appropriate safety precautions:
30 (2500)
Other pulse numbers on request.
* Version “N” with zero pulse only with connector M23.
Non-equivalence Monitoring
The non-inverted and inverted signal lines of each safety
track (A vs. A inv. and B vs. B inv.) must have non-equivalent
signal levels at all times. In state transition, very short periods of time (some microseconds) are permissible in which
both lines have same logical signal level. A dangerous error
occurs when this short period of time is exceeded.

Line break detection
Make sure none of the signal cables A, A inv, B, B inv. is
high-impedant. The encoder will utilize the high-impedant
status of the safety tracks A, A inv., B, B inv. to output an
error message.
Safe stop
In case of missing state changes in at least one of the
signals A, A inv., B, B inv., the customer has to ensure shaft
standstill by means of a second, independent safety precaution within an acceptable amount of time depending on the
facility.

Safe rotational speed
In the event of a predefined speed limit, the master control will require identical speed frequencies on both safety
tracks. If not, it is a fatal error.
Safe rotational direction
The phase shift of the safety relevant incremental signals A
vs. B and A inv. vs. B inv. has to be monitored. A dangerous
error occurs when exceeding the given tolerances. Compliance to the defined rotational direction has to be monitored
as well.
