Example with position control
Evaluation of bit: "Unfeasible or single-channel signal from the incremental
encoder", with position control
Diagnostic bit 10: "Unfeasible or single-channel signal from the incremental encoder" may
be set during position control as a result of jitter on the encoder.
The set bit can be tolerated, i.e. evaluated in the user program in such a way that a shut-
down will not occur if the following conditions are met:
} An additional position control signal must be provided from an external control system
(e.g. PLC) and
} The signal must have the following status conditions:
– Position control: Signal status = 1
– Operation: Signal status = 0
During operation, diagnostic bit 10 must be evaluated in the user program in such a way
that a set bit leads to a safety-related error reaction (shutdown).
