NOTE
6 When the manual handle/step feed mode or TEACH IN
STEP/HANDLE mode is selected while the CNC is
operating in the AUTO, RMT, or MDI mode, the automatic
or MDI operation stops, the STL signal turns to “0”, the SPL
signal simultaneously turns to “1”, and the CNC enters the
manual handle/step feed mode or TEACH IN STEP/
HANDLE mode. Manual handle feed or incremental feed by
axis direction select signal is possible under this state.
Since the AUTO, RMT, or MDI mode commands are held,
operation can be restarted by the cycle start signal by
selecting the AUTO, RMT, or MDI mode. However, if
operation was stopped by switching to the manual
handle/step feed mode or TEACH IN STEP/HANDLE mode
during manual data input or automatic operation, it can be
restarted only by the mode in use before the operation was
stopped (Fig. 2.6 (c)).
