In JOG mode, no axis that is traversed as geometry axis in the switched coordinate system, must be active as PLC or command axis (started through st atic synchronized action ) on mode change. This means that axes like that must be in the state 'neutral axis' again. Reaction: Alarm display. Remedy: Check the program status and channel status.
