[Design Precautions]
WARNING
●Configure safety circuits external to the programmable controller to ensure that the entire system
operates safely even when a fault occurs in the external power supply or the programmable controller.
Failure to do so may result in an accident due to an incorrect output or malfunction.
(1) Emergency stop circuits, protection circuits, and protective interlock circuits for conflicting
operations (such as forward/reverse rotations or upper/lower limit positioning) must be configured
external to the programmable controller.
(2) Machine OPR (Original Point Return) of the positioning function is controlled by two kinds of data:
an OPR direction and an OPR speed. Deceleration starts when the near-point watchdog signal
turns on. If an incorrect OPR direction is set, motion control may continue without deceleration. To
prevent machine damage caused by this, configure an interlock circuit external to the
programmable controller.
(3) When the CPU module detects an error during control by the positioning function, the motion slows
down and stops.
(4) The programmable controller stops its operation upon detection of the following status, and the
output status of the system will be as shown below.
Also, all outputs may be turned on if an error occurs in a part, such as an I/O control part, where
the programmable controller CPU cannot detect any error. To ensure safety operation in such a
case, provide a safety mechanism or a fail-safe circuit external to the programmable controller.
For a fail-safe circuit example, refer to the User's Manual (Hardware Design, Maintenance and
Inspection) for the CPU module used.
(5) Outputs may remain on or off due to a failure of a component such as a transistor in an output
circuit. Configure an external circuit for monitoring output signals that could cause a serious
accident.
●In an output circuit, when a load current exceeding the rated current 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.
●Configure a circuit so that the programmable controller is turned on first and then the external power
supply. If the external power supply is turned on first, an accident may occur due to an incorrect output
or malfunction.
●Configure a circuit so that the external power supply is turned off first and then the programmable
controller. If the programmable controller is turned off first, an accident may occur due to an incorrect
output or malfunction.
●For the operating status of each station after a communication failure, refer to relevant manuals for
each network. Incorrect output or malfunction due to a communication failure may result in an
accident.
Overcurrent or overvoltage protection of
the power supply module is activated.
The CPU module detects an error such as a
watchdog timer error by the self-diagnostic function.

[Design Precautions]
●When changing data from a peripheral device connected to the CPU module during operation,
configure an interlock circuit in the program to ensure that the entire system will always operate safely.
For other controls to a running programmable controller (such as program modification or operating
status change), read relevant manuals carefully and ensure the safety before the operation.
Especially, in the case of a control from an external device to a remote programmable controller,
immediate action cannot be taken for a problem on the programmable controller due to a
communication failure. To prevent this, configure an interlock circuit in the program, and determine
corrective actions to be taken between the external device and CPU module in case of a
communication failure.
●An absolute position restoration by the positioning function may turn off the servo-on signal (servo off)
for approximately 20ms, and the motor may run unexpectedly. If this causes a problem, provide an
electromagnetic brake to lock the motor during absolute position restoration.
CAUTION
●Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction
due to noise.
●During control of an inductive load such as a lamp, heater, or solenoid valve, a large current
(approximately ten times greater than normal) may flow when the output is turned from off to on.
Therefore, use a module that has a sufficient current rating.
●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 the time.
