Design Precautions
●In an output module, 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.
●For the operating status of each station after a communication failure, refer to relevant manuals for the
network.
Incorrect output or malfunction due to a communication failure may result in an accident.
●When controlling (changing data) the running programmable controller from a peripheral connected to the
CPU module or from a personal computer connected to an intelligent function module, configure an interlock
circuit in the sequence program to ensure that the entire system will always operate safely.
For other controls for the running programmable controller (program modification and operating status
change (status control)), read relevant manuals carefully, and ensure the safety before 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.
Configure an interlock circuit in the sequence program, and determine corrective actions to be taken
between the external device and CPU module in case of a communication failure.
●Do not install the control lines or communication cables together with the main circuit lines or power cables.
Keep a distance of 100mm (3.94 inches) or more between them.
Failure to do so may result in malfunction due to noise.
●When a device such as a lamp, heater, or solenoid valve is controlled through an output module, a large
current (approximately ten times greater than normal) may flow when the output is turned from off to on.
Take measures such as replacing the module with one having a sufficient current rating.
●The time for the CPU module to enter the RUN status after the CPU module is powered off and on or reset
will vary depending on the system configuration, parameter settings, and/or program size, etc.
Design the program so that the entire system will operate safely even if the time to reach the RUN status
varies.
●Use the programmable controller in an environment that meets the general specifications in the QCPU
User's Manual (Hardware Design, Maintenance and Inspection).
Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of the product.

screw.
Tighten the screw within the specified torque range.
Undertightening can cause drop of the screw, short circuit or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
●When using an extension cable, connect it to the extension cable connector of the base unit securely.
Check the connection for looseness.
Poor contact may cause incorrect input or output.
●When using an SD memory card, fully insert it into the SD memory card slot.
Check that it is inserted completely.
Poor contact may cause malfunction.
●When using an extended SRAM cassette, fully insert it into the cassette connector on the CPU module.
Close the cassette cover to keep the extended SRAM cassette inserted completely.
Poor contact may cause malfunction.
●Shut off the external power supply for the system in all phases before mounting or removing the module.
Failure to do so may result in damage to the product.
A module can be replaced online (while power is on) on any MELSECNET/H remote I/O station or in the
system where a CPU module supporting the online module change function is used.
Note that there are restrictions on the modules that can be replaced online, and each module has its
predetermined replacement procedure.
For details, refer to the relevant sections in the QCPU User's Manual (Hardware Design, Maintenance and
Inspection) and in the manual for the corresponding module.
●Do not directly touch any conductive part or electronic component of the module, memory card, SD memory
card or extended SRAM cassette. Doing so can cause malfunction or failure.

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) Configure external safety circuits, such as an emergency stop circuit, protection circuit, and protective
interlock circuit for forward/reverse operation or upper/lower limit positioning.
(2) The mechanical zero return of the positioning function is controlled based on two parameters, zero
return direction and zero return speed, and deceleration is started when the near-point dog is turned
on. Therefore, if the zero return direction is set incorrectly, the positioning function may continue the
operation without deceleration. Configure an interlock circuit for prevention of mechanical damage on the
outside of the programmable controller.
(3) When the CPU module detects an error during operation of the positioning function, the function will
decelerate and stop.
(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.
•When the overcurrent or overvoltage protection of the power supply module is activated, all outputs
will be turned off.
•When the CPU module detects an error such as a watchdog timer error by the self-diagnostic
function, all outputs will be held or turned off according to the parameter setting.
All outputs may turn on when an error occurs in the part, such as I/O control part, where the
CPU module 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 LOADING AND INSTALLATION in the LCPU User's Manual (Hardware Design,
Maintenance and Inspection).
(5) Outputs may remain on or off due to a failure of a transistor on 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 before the programmable controller is
turned off.
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 network communication failure, refer to relevant manuals for
the network. Incorrect output or malfunction due to a communication failure may result in an accident.
●When changing data of the running programmable controller from a peripheral connected to the CPU
module, configure an interlock circuit in the program to ensure that the entire system will always operate
safely.
For other controls for the running programmable controller (program modification and operating status
change (status control)), read relevant manuals carefully, and ensure the safety before 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.
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.
●If an absolute position is recovered by the positioning function, the servo ON signal may be kept off (the
servo may be kept off) for approx. 20 ms, and the motor may operate. If any problem is caused by the motor
operation when the servo ON signal is turned off, provide an electromagnetic brake so that the motor will be
locked during absolute position recovery.

CAUTION
●Ground the FG and LG terminals to the dedicated conductors for the programmable controller (Class D
(Class 3) or higher grounding).
Failure to do so may result in electric shock or malfunction.
●Use applicable solderless terminals and tighten them within the specified torque range.
If any spade solderless terminal is used, it may be disconnected when the terminal screw comes loose,
resulting in failure.
●Check the rated voltage and terminal layout before wiring to the module, and connect the cables correctly.
Inputting voltage different from the rated voltage, connecting a power supply with a different voltage rating or
incorrect wiring may cause a fire or failure.
●Connectors for external connection must be crimped or pressed with the tool specified by the manufacturer,
or must be correctly soldered.
Incomplete connections could result in short circuit, fire, or malfunction.
●Fit the connectors surely to the module.
●Do not bundle the control cable or communication cable with the main circuit or power wire, or lay them
adjacently. Separate these by 100 mm or more as a rule.
Failure to observe this could lead to malfunctioning caused by noise.
●The electric wires and cables connected to the module shall be installed in a duct or secured with clamps.
If such measures are not taken, the cables may sway or move or may be pulled unintentionally, and the
module and cables may be damaged, or malfunction may be caused by cable contact failure.
●When connecting any cable, check the type of the interface to be connected.
Connecting to an improper interface or incorrect wiring may damage the module and external devices.
●Tighten the screws on the terminal block within the specified torque range. Undertightening the screws can
cause short circuit, a fire or malfunction.
Overtightening can damage the screws and/or module, thereby causing fall, short circuit, a fire and
malfunction.
●When disconnecting any cable from the module, do not pull the cable. When disconnecting a cable with a
connector, hold the connector of the connecting part of the module. Before disconnecting a cable from the
terminal block, loosen the terminal screw on the terminal block.
Pulling the cable with the terminal connected to the module may cause malfunction or damage to the module
or cable.
●Prevent foreign matter such as dust or wire chips from entering the module.
Such foreign matter can cause a fire, failure, or malfunction.
●A protective film is attached to the top of the module to prevent foreign matter, such as wire chips, from
entering the module during wiring. Do not remove the film during wiring. Remove it for heat dissipation before
system operation.
●When using the high-speed counter function, ground the shielded wire on the encoder side (relay box).
(Class D (Class 3) grounding or higher)
Failure to do so may cause malfunction.
