5021: Limit switch closed: No direction change for this homing mode

Info:
Data type:

Description:
A homing mode was defined which does not allow a change of direction at the HW limits.
Response error if a limit switch in the start direction is already closed (ncABS_SWITCH) when the 'start homing procedure' command is given.
Runtime error during homing procedure if a limit switch signal occurred (ncABS_SWITCH, ncEND_SWITCH).

Reaction:
When 'start homing procedure' command: See error number 5017.
When homing procedure: See error number 5035.

Cause/Remedy:
The HW limit was reached while searching for the edge of the absolute reference switch.
-> HW error at reference switch (wire break, line termination, wiring error, supply voltage).
The reference switch is mounted too close to the limit switch.
