The slave axis must not be a main spindle.
Description | When a coupling group is selected (#ENABLE AX LINK [..] or #AX LINK ON [..]), the program detects that the slave axis of a coupling pair of spindle axes is the main spindle. This is not allowed.
Response | Class | 2 | Abort NC program processing.
Solution | Class | 3 | Check and modify the NC program. Reverse definition of spindle coupling so that the master axis is the main spindle or, before the affected coupling group is selected, define the spindle master axis as the main spindle using #MAIN SPINDLE.
