Deactivate external encoder (bit 11)

INFORMATION

Before the Deactivate external encoder bit (bit 11) is reset, the Activate inhibit bit (bit 13) must be set in order to initialize the controller again.

In the event of a defective encoder, the storage/retrieval system can be moved in emergency mode by setting the Deactivate external encoder bit (bit 11). In this case only jog mode is possible because the absolute position is no longer available. Additionally, in a hoist with a steel cable, the winch can be moved without the lifting trolley – and therefore the external encoder – having to be in motion (e.g., rewinding the cable onto the drum during servicing). As long as the external encoder is deactivated, the "Referenced" bit in the status word is set to "FALSE".
