Info: Slot
Data type: USINT

Description:
Runtime error in an incremental encoder with activated monitor (activation, see error number 7030). Signal A and nA must complement each other. Overlapping only occurs in the area of the switching edges. A cable disturbance is registered if the low or high level overlap for a long period of time.

Reaction:
See error number 7030.

Cause/Remedy:
Encoder is not connected.
No encoder supply or supply contains an error.
Encoder connection is interrupted or defective. See wiring guidelines error number 7030.
