(c) The rapid stop command in a dwell time is invalid. (After a dwell time, the
start accept flag (M2001+n) turns OFF, and the positioning complete signal
(M4001+20n) turns ON.)
REMARK
(Note-1) : Rapid stop processing is deceleration stop with deceleration time set in
the parameter block or servo program.
(3) Forward rotation JOG start command (M4802+20n)/Reverse
rotation JOG start command (M4803+20n) ......... Command signal
(a) JOG operation to the address increase direction is executed while forward
rotation JOG start command (M4802+20n) is turning on.
When M4802+20n is turned off, a deceleration stop is executed in the
deceleration time set in the parameter block.
(b) JOG operation to the address decrease direction is executed while reverse
rotation JOG start command (M4803+20n) is turning on.
When M4803+20n is turned off, a deceleration stop is executed in the
deceleration time set in the parameter block.
POINT
Take an interlock so that the forward rotation JOG start command (M4802+20n)
and reverse rotation JOG start command (M4803+20n) may not turn on
simultaneously.
