CC speed greater than SRG %1

What does 231-A820 mean?

This error indicates that the maximum permissible velocity in the SRG (Safe Reduced Speed) operating mode was exceeded for the CC controller. This typically occurs when a feed rate or shaft speed is too high while in SRG mode, often with safety doors open, or due to incorrect parameter settings.

• The maximum permissible velocity in the SRG operating mode was exceeded.
• Feed rate or shaft speed was too high before or during SRG mode activation.
• Incorrect operating mode selected (key-operated switch).
• Incorrect parameter values for SRG velocity limits.

Click steps to track your progress.

1. 1

   Reduce the feed rate and shaft speed significantly before opening safety doors or activating SRG operating mode.

2. 2

   Check the position and setting of the key-operated switch to ensure the correct operating mode (SRG) is selected.

3. 3

   Verify that all parameter values related to SRG velocity limits are correctly set and correspond to the machine's safety specifications.

4. 4

   Inspect the machine's safety doors and their interlocks to ensure they are functioning correctly and registering their state.
