• Move the RUN/STOP switch from RUN to STOP.
(2) Start accept flag (M2001 to M2032) ............................ Status signal
(a) This flag turns on when the servo program is started. The start accept flag
corresponding to an axis specified with the servo program turns on.
(b) The ON/OFF processing of the start accept flag is shown below.
1) When the servo program is started using the Motion SFC program or
Motion dedicated PLC instruction (S(P).SVST), the start accept flag
corresponding to an axis specified with the servo program turns on and
it turns off at the positioning completion. This flag also turns off when it
is made to stopping on the way.
(When it is made to stop on the way by the speed change to speed "0",
this flag remains on.)
