Siemens 840D 61329 - Channel Block: Check rotary axis

Alarm 61329 indicates that CYCLE998 attempted to reference a rotary axis via the _RA parameter, but the specified axis number either has no valid axis name assignment in the NCK or is not configured with the rotary axis attribute. This occurs during machine tool cycle execution when axis classification validation fails.

Causes and Fixes

1
Access Siemens HMI menu: Diagnosis > Machine data > Search for MD 20080. Verify that the axis number used in _RA parameter has a valid axis name assigned (e.g., 'A', 'B', 'C').
2
If axis name is missing, navigate to Setup > Axes > Axis configuration in the control panel and assign an axis name to the corresponding axis number in the NCK table.
3
After modification, perform a warm restart (Control > Reset) and verify MD 20080 entry persists in the NCK axis name lookup table.
Warm restart will halt active programs; execute during maintenance windows only.
