(b) Rapid stop command (M4801+20n)
1) This command is used to execute a rapid stop at an axis which is in
motion, and it becomes effective at its leading edge (OFF→ON).
(Operation cannot be started at axes where the rapid stop command is
ON.)

REMARKS
(Note): Rapid stop processing results in deceleration to a stop within the rapid
stop deceleration time designated at the parameter block or servo
program.
(c) Forward JOG start command (M4802+20n)/Reverse JOG start command
(M4803+20n)
1) When the forward JOG start command (M4802+20n) is ON in the
sequence program, JOG operation occurs in the forward direction
(direction in which the address increases).
When the forward JOG start command (M4802+20n) is switched OFF, a
deceleration and STOP will occur within the deceleration time designated
at the parameter block.
2) When the reverse JOG start command (M4803+20n) is ON in the
sequence program, JOG operation occurs in the reverse direction
(direction in which the address decreases).
When the reverse JOG start command (M4803+20n) is switched OFF a
deceleration and STOP will occur within the deceleration time designated
at the parameter block.
