Example
Connection
Interrupt stop
(linear interpolation [Interrupt
stop])
If an interrupt input turns ON,
during a linear interpolation
operation to the target posi-
tion (x, y) at a vector speed,
the speed will decelerate and
the positioning operation will
stop.
− −−−33
Interrupt stop
If an interrupt input turns ON,
during a positioning opera-
tion, the speed will deceler-
ate and the operation will
stop.
−−33−3
Interrupt 1-speed positioning
(Interrupt 1-speed constant
quantity feed) If an interrupt input turns ON,
the workpiece will travel to
the specified transfer dis-
tance at the same speed,
where it will decelerate and
the operation will stop.
3*6 3333 3
2-speed positioning with
speed reduction
The operation starts at oper-
ation speed (1) by the start
command. During the opera-
tion, if the speed reduction
command is input, the speed
will decelerate to operation
speed (2). After that, the
operation will be continued at
operation speed (2) until the
stop command is input.
−3−−− −
Interrupt 2-speed positioning
(Interrupt 2-speed constant
quantity feed)
If interrupt input(1) turns ON,
the speed will be reduced to
the 2nd speed. After that, if
interrupt input(2) turns ON,
the operation will decelerate
to stop after moving the
specified transfer distance at
the 2nd speed.
