MC_2977:
Stop/Start spindle
during Hold/Start
During Automatic operations (that is,
Auto or Single Step), the CNC has the
capability of automatically stopping the
spindle when the
Hold
key is pressed
and re-starting the spindle when the
Start
key is pressed. The spindle is re-
started only if it was previously running.
NOTE:
This feature also applies to
External Hold and External Start input
functions.
No
[Default]
Yes
If you specify
Yes
, this feature is
enabled. Sending the appropriate
M-codes through the interface
does the stopping and starting of
the spindle. That is, M5 is sent for
stopping, and M3 or M4 (based on
which one was active when the
spindle was stopped) is sent for
starting.
