NOTE
5 When the HANDLE/INC mode is selected while the
CNC is operating in the MEM 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 HANDLE/INC mode.
Under these conditions, manual handle feed or
incremental feed by axis direction select signal is
permitted. Since the MEM mode or MDI mode
commands are held, operation can be restarted by
the cycle start signal and by selecting the MDI or
MEM mode. However, if operation was stopped by
switching to the HANDLE/INC mode during manual
data input or during automatic operation, it can be
restarted only by reactivating the mode in use
before the operation was stopped (Fig. 2.6 (c)).
