CC%2 operating state not equal MC

Was bedeutet 231-A080 ?

This error indicates a discrepancy between the operating conditions of the MC (Machine Control) and CC (Controller) modules. Specifically, the automatic, SRG (Reduced Speed), SBH (Standstill Monitoring), and SH (Safe Hold) operating conditions are cyclically compared, and if they remain unequal for longer than 500 ms, a Stop 1 safety reaction is triggered.

• Automatic, SRG, SBH, and SH operating conditions are unequal between MC and CC for >500 ms.
• Mismatched software versions between MC and CC.
• Communication error between MC and CC leading to inconsistent status reporting.
• Internal software error within MC or CC modules.

1. 1

   Acknowledge the error message with CE on the HMI.

2. 2

   Attempt to switch on the machine to see if the error clears and conditions synchronize.

3. 3

   Verify that the software versions of both the MC and CC modules are compatible and up-to-date according to Heidenhain documentation.

4. 4

   Check the communication links (e.g., cables, bus terminations) between the MC and CC for integrity and proper functioning.
