Causes and Fixes

1
Check the alarm detail for the specific channel (%1) and mode group (%2) numbers to identify which NC channels are involved.
2
Review the part program for WAITM, WAITMC, or synchronization commands that may be creating deadlock conditions between channels.
3
Verify axis assignment in machine data MD20070 (AXCONF_MACHAX_USED) and MD20080 (AXCONF_CHANAX_NAME_TAB) to ensure no conflicts between channels in the mode group.
Incorrect machine data modification can cause machine malfunction. Document original values before changes.
4
Reset the alarm using RESET key, select the affected channel, and restart program execution. Monitor for recurrence at the same program block.
