In the case of an
emergency stop or a
stop caused by a limit
switch.
Interlock circuits as
necessary.Provide
external interlock
circuits for conflicting
operations, such as
forward rotation and
reverse rotation, and
for parts that could
damage the machine
or cause accidents if
no interlock were used.
Power to output equipment
switched OFF when the
STOP signal is given.
In the case of an

or a stop caused
by a limit switch.
Power to output
equipment
switched OFF
when the STOP
signal is given.

The power-ON procedure is as follows:
For AC
For AC/DC
1) Switch power ON.
2) Set CPU to RUN.
3) Turn ON the start switch.
4) When the magnetic contactor (MC) comes on, the output
equipment is powered and may be driven by the program.
1) Switch power ON.
2) Set CPU to RUN.
3) When DC power is established, RA2 goes ON.
4) Timer (TM) times out after the DC power reaches 100%.
(The TM set value should be the period of time from when
RA2 goes ON to the establishment of 100% DC voltage.
Set this value to approximately 0.5 seconds.)
5) Turn ON the start switch.
6) When the magnetic contactor (MC) comes on, the output
equipment is powered and may be driven by the program.
(If a voltage relay is used at RA2, no timer (TM) is required
in the program.)
