Category: Alarm
Cause
- The motor rotation direction is opposite to the external encoder installation direction
- Incorrect installation of the connection between the load position, such as the workpiece table, and the external encoder
Corrective action
- Check motor rotation direction and external encoder installation direction; reverse the external encoder installation direction, or set the rotation direction in External encoder usage method (Pn002.3) to the opposite direction.
- Check the external encoder coupling; reconnect the mechanical coupling.
