INTERNAL ERROR (GROUPERR_SLAVE_INTERNAL)

Hva betyr 42FB ?

An unspecified internal error has occurred within the NC system concerning a slave axis within a group. This indicates a low-level software fault or data inconsistency that prevents the slave axis from functioning correctly. Such internal errors can lead to group motion failure or loss of control over the slave axis.

• Transient data corruption in the NC runtime memory affecting a slave axis's internal state or control loop.
• Race condition or timing issue in the NC kernel when processing commands for a specific slave axis within a group.
• Firmware bug in the servo drive for the slave axis or an issue with EtherCAT master/slave communication stability.
• Corrupted configuration data for the slave axis, leading to internal calculation errors within the NC system.
• Heavy system load or insufficient processing power on the industrial PC (IPC) causing internal timeouts for slave axis control.
• Incompatible version of NC runtime software or slave drive firmware preventing proper communication.

1. 1

   1. Perform an NC reset using the TwinCAT System Manager, followed by a full controller reboot to clear any transient software errors.

2. 2

   2. Verify the slave axis configuration in the NC against a known good backup, checking for any inconsistencies.

3. 3

   3. Check the EtherCAT diagnostics for the specific slave axis for any communication errors, frame losses, or unexpected states.

4. 4

   4. Ensure that the NC runtime version and the slave drive's firmware version are compatible according to the manufacturer's specifications.

5. 5

   5. If the error persists, collect a diagnostic log and the complete TwinCAT project file, then contact technical support for deeper analysis.
