NOTE
7 When the JOG or TEACH IN JOG mode is selected during
RMT, MEM or MDI mode operation, operation stops, the
STL signal turns to “0”, the SPL signal simultaneously turns
to “1”, and the CNC enters the JOG or TEACH IN JOG
mode. Under these conditions, manual feed by feed axis
direction select signal is permitted. Operation can be
restarted by returning to the original mode, as described for
HANDLE/STEP or TEACH IN HANDLE mode (Fig. 2.6 (d)).
When the mode is switched to the JOG or TEACH IN JOG
mode during manual handle feed or during step feed
operation, the CNC ignores the manual handle feed or step
feed command and manual jog feed becomes effective. If
a feed axis direction select signal turns to “1” before the JOG
or TEACH IN JOG mode is selected, that signal is ignored.
The feed axis select signal is selected by turning the
necessary feed axis direction signal to “1” after turning all
the feed axis direction select signals to “0” (Fig. 2.6 (e)).
It is possible to perform handle feed in TEACH IN JOG mode
by activating parameter THD no.7100#1. For details, refer
to item (2), (4).
