Remarks
ular mode to complete when gear change commands are output
during the operation of synchronous tapping cycle/tapping cycle/
thread cutting.
Do not output the gear change command during the fixed cycle for
drilling. Changing gears during the fixed cycle for drilling changes
the speed of the spindle, which may prevent processing from being
performed correctly.
Do not output gear change commands during the dwell (Revolution-
based designation). Changing gears during the dwell (Revolution-
based designation) changes the speed of the spindle, which may
prevent the dwell (Revolution-based designation) from being per-
formed correctly.
Do not output the gear change command during the feed per revo-
lution operation. Changing gears during the feed per revolution op-
eration changes the speed of the spindle, which may prevent the
feed per revolution operation from being performed correctly.
