Drive hardware not ready to operate
Beckhoff · TwinCAT 2 NC
What does 4650 mean?
The drive hardware is not in a ready state for operation. This can be caused by the drive being in a hardware error state, still undergoing its start-up phase (which can take several seconds after a reset), or missing the necessary controller enable signal. Until the drive is ready, no motion commands can be executed.
Complete Troubleshooting Guide
- 1
Check the drive's status indicators for any active hardware errors and clear them according to the drive's manual.
- 2
Allow sufficient time for the drive to complete its internal booting sequence, especially after power cycling or a hard reset.
- 3
Verify that the controller enable (ENABLE) signal is active and stable, and troubleshoot any interlocks preventing it.
- 4
Inspect the drive's power supply and communication connections for stability.
