NOTE
Precautions on modes and mode switching
1 In MDI mode, the STL signal turns to “0” and the CNC stops
as soon as the commands entered via the MDI have been
executed. But the SPL signal does not turn to “1”. Therefore,
another command can be entered from the manual data
input unit under this condition.
2 Manual operation in jog feed mode
a) When bit 0 (JHD) of parameter No. 7100 is set to 0
Only jog feed is possible.
b) When bit 0 (JHD) of parameter No. 7100 is set to 1
Both jog feed and manual handle feed are possible. Jog
feed and manual handle feed cannot, however, be
performed simultaneously. Manual handle feed can be
performed when the tool is not being moved by means
of jog feed.
3 Manual operation in manual handle/incremental feed.
a) When bit 0 (JHD) of parameter No. 7100 is set to 0
Only manual handle feed is possible.
b) When bit 0 (JHD) of parameter No. 7100 is set to 1
Manual handle feed and incremental feed is possible.
Manual handle feed and incremental feed cannot,
however, be performed simultaneously. Manual handle
feed can be performed when the tool is not being moved
by means of incremental feed.
