4223
No enable for controller and/or feed (Master axis)
Beckhoff · TwinCAT 2 NC
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.
Complete Troubleshooting Guide
- 1
Check the status of the controller enable signal for the master axis.
- 2
Verify that the relevant direction-dependent feed enable signals are active via the `PlcToNc` interface.
- 3
Troubleshoot any external safety circuits, interlocks, or PLC logic that might be holding the enables inactive.
- 4
Ensure all safety conditions are met, such as guard doors closed or emergency stops reset, that could affect enables.
