[3] Pause Circuit
Pause is provided by a single pushbutton. In a similar way as use of an alternate switch, push
the button to make the actuator pause and push it again to release the pause of the actuator.
Pushing the pushbutton leads the “pause command and pause lamp ON” state and pushing the
pushbutton again brings “pause release command and pause lamp OFF”.

To make it easy to understand the circuit, this circuit is
designed to replace contact b input with contact a. If the
pause button is pushed, the circuit turns AUX1 ON.
This circuit goes on the lamp if it is off.
(Interlock)
Without this, AUX2 and AUX3 continue to be ON
alternately every other scan while the button is pushed.
This circuit goes off the lamp if it is on.
If emergency stop occurs during
pause, this releases the pause.
After resetting during pause, the
timer waits for cancellation of the
remaining moving distance.
