No enable for controller and/or feed (Master axis)

What does 4223 mean?

The necessary enable signals for the master axis, such as the controller enable or direction-dependent feed enables (via the PlcToNc interface), are not active. Without these enables, the axis controller cannot operate, preventing any motion or positioning tasks from executing. This is a critical safety interlock.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Troubleshoot any external safety circuits, interlocks, or PLC logic that might be holding the enables inactive.

2. 4

   Ensure all safety conditions are met, such as guard doors closed or emergency stops reset, that could affect enables.
