官方故障排除步驟
Parameters: %1 = Channel number %2 = Axis name, spindle number Definitions: 'JOG to position' is active for t he axis, but an offset motion - for example a synchronization offset $AA_OFF - has been interpolated simultaneously. The position of the SD43320 $SA_JOG_POSITION is not reached if offset values are changed during the traversing motion. The target point then becomes "Jog position + change in offset value". The position SD43320 $SA_JOG_POSITION will be reac hed if the traversing motion is restarted after the offset value has been changed. (For example: incremental traversing in whic h the traversing motion stops intermittently). Reason: Restarting the motion takes the current offset value into account. Reaction: Interface signals are set. Alarm display. Remedy: Trigger JOG motion again. Program Continuation: Clear alarm with the Delete key or NC START.
