[DESIGN PRECAUTIONS]
WARNING
●Make sure to set up the following safety circuits outside the PLC to ensure safe system operation
even during external power supply problems or PLC failure. Otherwise, malfunctions may cause
serious accidents.
- Most importantly, set up the following: an emergency stop circuit, a protection circuit, an
interlock circuit for opposite movements (such as forward vs. reverse rotation), and an interlock
circuit to prevent damage to the equipment at the upper and lower positioning limits.
- Note that when the CPU module detects an error, such as a watchdog timer error, during self-
diagnosis, all outputs are turned off. Also, when an error that cannot be detected by the CPU
module occurs in an input/output control block, output control may be disabled. External
circuits and mechanisms should be designed to ensure safe machine operation in such a case.
- Note that when an error occurs in a relay, transistor or triac of an output circuit, the output
might stay on or off. For output signals that may lead to serious accidents, external circuits and
mechanisms should be designed to ensure safe machine operation.
●Construct an interlock circuit in the program so that the whole system always operates on the safe
side before executing the control (for data change) of the PLC in operation.
Read the manual thoroughly and ensure complete safety before executing other controls (for program
change, parameter change, forced output and operation status change) of the PLC in operation.
Otherwise, the machine may be damaged and accidents may occur due to erroneous operations.
●In an output circuit, when a load current exceeding the current rating or an overcurrent caused by
a load short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure an
external safety circuit, such as a fuse.
●For the operating status of each station after a communication failure of the network, refer to relevant
manuals for the network. Incorrect output or malfunction may result in an accident.

[DESIGN PRECAUTIONS]
CAUTION
●When an inductive load such as a lamp, heater, or solenoid valve is controlled, a large current
(approximately ten times greater than normal) may flow when the output is turned from off to on.
Take proper measures so that the flowing current does not exceed the value corresponding to the
maximum load specification of the resistance load.
●After the CPU module is powered on or is reset, the time taken to enter the RUN status varies
depending on the system configuration, parameter settings, and/or program size.
Design circuits so that the entire system will always operate safely, regardless of this variation in time.
●Simultaneously turn on and off the power supplies of the CPU module and extension modules.
●If a long-time power failure or an abnormal voltage drop occurs, the PLC stops, and output is
turned off. When the power supply is restored, it will automatically restart (when the
RUN/STOP/RESET switch is on RUN side).
