This error indicates that a drive (or multiple drives) has been locked by the safety software of the CC (Controller) module. This occurs when an emergency stop is active (due to -ES.B or -NE2 signal) and an attempt is made to switch on a drive, or due to an internal software error.
Click steps to track your progress.
Verify the status of the emergency stop circuit and the -ES.B or -NE2 signals. Ensure the E-stop is reset.
Check the wiring of the emergency stop circuit to the CC module for integrity, shorts, or breaks.
Confirm that all safety doors and interlocks are closed and secured, as they might trigger an emergency stop condition.
Verify the software version of the CC module and update it if a known bug fix is available.
