Okuma Alarm-A 1725 Impossible command issued during spindle synchronization
With multi-process machining models (sub-spindle specification models, FTL, etc.), the spindle rotation command, an S command, or the rotation range command for the A-spindle is designated in the spindle synchronized rotation mode. Or with multi-process machining models (sub-spindle specification models, FTL, etc.), the rotation range command for the B-spindle is designated in the spindle synchronized rotation mode. (Assume that the A-spindle is controlled in synchronization with the Bspindle rotation.)
