Drive lock through safety software (CC)

What does 231-A090 mean?

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.

• Emergency stop activated (by CC) via -ES.B or -NE2 signal.
• Attempt to switch on a drive while the system is in an 'emergency stop' condition.
• Internal software error within the CC module.

Click steps to track your progress.

1. 1

   Verify the status of the emergency stop circuit and the -ES.B or -NE2 signals. Ensure the E-stop is reset.

2. 2

   Check the wiring of the emergency stop circuit to the CC module for integrity, shorts, or breaks.

3. 3

   Confirm that all safety doors and interlocks are closed and secured, as they might trigger an emergency stop condition.

4. 4

   Verify the software version of the CC module and update it if a known bug fix is available.
