2. PREPARATIONS FOR OPERATION
136
NOTE
6 When the HANDLE/INC or TEACH IN HANDLE 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 or TEACH IN HANDLE
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 or TEACH IN
HANDLE 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)).
