2. PREPARATIONS FOR OPERATION

NOTE
Precautions on modes and mode switching
1 In the MDI mode, the STL signal turns to “0” and the CNC
stops at the end of execution of the commands input from
the CRT/MDI panel, but the SPL signal does not turn to “1”.
Therefore, another command can be input from the manual
data input unit under this state.
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, the
manual handle feed is used. 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 TEACH IN JOG and TEACH IN
HANDLE mode.
a) When parameter JHD no.7100#0 is set to ”0” so that jog
operation and handle feed operation are performed with
separate modes:
In TEACH IN JOG mode, jog operation can be done.
In TEACH IN HANDLE mode, handle feed can be done
when manual handle feed function is not used, and
incremental feed can be done when handle feed function
is not provided.
b) When parameter JHD no.7100#0 is set to “1” so that jog
operation and handle feed operation are performed with
the same mode:
In TEACH IN JOG mode, handle feed and jog feed can
be done when manual handle feed function is not used,
but jog feed only when it is not included.
In TEACH IN HANDLE mode, handle feed and jog feed
can be done when manual handle feed function is not
used, but incremental feed only when it is not included.
The program can be edited in both TEACH IN JOG and
TEACH IN HANDLE modes.
