[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) When the programmable controller detects an abnormal condition, it stops the operation and all
outputs are:
Turned off if the overcurrent or overvoltage protection of the power supply module is activated.
Held or turned off according to the parameter setting if the self-diagnostic function of the CPU
module detects an error such as a watchdog timer error.
(3) All outputs may be turned on if an error occurs in a part, such as an 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 "General Safety Requirements" in the MELSEC iQ-R Module Configuration
Manual.
(4) Outputs may remain on or off due to a failure of a component such as a relay and 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.
For the operating status of each station after a communication failure, refer to manuals relevant to the
network. Incorrect output or malfunction due to a communication failure may result in an accident.
When connecting an external device with a CPU module or intelligent function module to modify data
of a running programmable controller, configure an interlock circuit in the program to ensure that the
entire system will always operate safely. For other forms of control (such as program modification,
parameter change, forced output, or operating status change) of a running programmable controller,
read the relevant manuals carefully and ensure that the operation is safe before proceeding. Improper
operation may damage machines or cause accidents.
[Design Precautions]
[Design Precautions]
WARNING Especially, when a remote programmable controller is controlled by an external device, immediate
action cannot be taken if a problem occurs in 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.
Do not write any data to the "system area" and "write-protect area" of the buffer memory in the
module. Also, do not use any "use prohibited" signals as an output signal from the CPU module to
each module. Doing so may cause malfunction of the programmable controller system. For the
"system area", "write-protect area", and the "use prohibited" signals, refer to the user's manual for the
module used.
If a communication cable is disconnected, the network may be unstable, resulting in a communication
failure of multiple stations. Configure an interlock circuit in the program to ensure that the entire
system will always operate safely even if communications fail. Failure to do so may result in an
accident due to an incorrect output or malfunction.
To maintain the safety of the programmable controller system against unauthorized access from
external devices via the network, take appropriate measures. To maintain the safety against
unauthorized access via the Internet, take measures such as installing a firewall.
Outputs may remain on or off due to a failure of a transistor for external output. Configure an external
circuit for monitoring output signals that could cause a serious accident.
CAUTION 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.
Do not power off the programmable controller or reset the CPU module while the setting values in the
buffer memory are being written to the flash ROM in the module. Doing so will make the data in the
flash ROM undefined. The values need to be set in the buffer memory and written to the flash ROM
again. Doing so also can cause malfunction or failure of the module.
When changing the operating status of the CPU module from external devices (such as the remote
RUN/STOP functions), select "Do Not OPEN in Program" for "Open Method Setting" in the module
parameters. If "OPEN in Program" is selected, an execution of the remote STOP function causes the
communication line to close. Consequently, the CPU module cannot reopen the line, and external
devices cannot execute the remote RUN function.
Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 150mm or more between them. Failure to do so may result in malfunction
due to noise.

solderless terminal is used, it may be disconnected when the terminal screw comes loose, resulting in
failure.
Check the rated voltage and signal layout before wiring to the module, and connect the cables
correctly. Connecting a power supply with a different voltage rating or incorrect wiring may cause fire
or failure.
Connectors for external devices must be crimped or pressed with the tool specified by the
manufacturer, or must be correctly soldered. Incomplete connections may cause short circuit, fire, or
malfunction.
Securely connect the connector to the module. Poor contact may cause malfunction.
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.
Place the cables in a duct or clamp them. If not, dangling cable may swing or inadvertently be pulled,
resulting in damage to the module or cables or malfunction due to poor contact. Do not clamp the
extension cables with the jacket stripped.
Check the interface type and correctly connect the cable. Incorrect wiring (connecting the cable to an
incorrect interface) may cause failure of the module and external device.
Tighten the terminal screws or connector screws within the specified torque range. Undertightening
can cause drop of the screw, short circuit, fire, or malfunction. Overtightening can damage the screw
and/or module, resulting in drop, short circuit, fire, or malfunction.
When disconnecting the cable from the module, do not pull the cable by the cable part. For the cable
with connector, hold the connector part of the cable. For the cable connected to the terminal block,
loosen the terminal screw. Pulling the cable connected to the module may result in 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.

5 INSTALLATION AND WIRING
This chapter describes the installation and wiring of the high-speed counter module.
5.1 Wiring This section describes the method of wiring an encoder and a controller to the high-speed counter module.
Wiring precautions To obtain the maximum performance from the functions of the high-speed counter module and improve the system reliability,
an external wiring with high durability against noise is required. Here are some precautions when wiring a encoder or a
controller.
Wiring Different terminals are prepared depending on the voltage of the signal to be input. Connecting to a terminal with a different
voltage may cause malfunction of the module or failure of the connected devices.
In 1-phase input, always connect a pulse input cable on the A-phase side.
To prevent burnout or damage of the external devices and module in the event of a load short circuit, install a fuse for each
one external terminal in the output circuit.
The following table lists the operation checked fuses:
Connectors for external devices Connectors for external devices must be soldered or crimped properly. A poor soldering or crimping may result in
malfunction.
Securely connect the connectors for external devices to the connectors of the high-speed counter module, and securely
tighten the two screws.
When removing a cable from the high-speed counter module, do not pull the cable by the cable part. Remove a cable
supporting the connector part of the cable by hand. Pulling the cable being connected to the high-speed counter module
can cause malfunction. In addition, a damage of the high-speed counter module or cables can result.

Measures against noise The high-speed counter module may count pulses incorrectly if pulse-like noise is input.
For the input of high-speed pulses, take the following measures against noise:
Measure 1: Be sure to use the shielded twisted pair cables.
Measure 2: Keep the shielded twisted pair cable at a distance of 150mm or more away from power lines and I/O lines
containing much noise, with the cable not being close to them. The wiring distance also should be as short as possible.
Measure 3: Ground the shielded cable on the encoder side (relay box). Individually ground the FG and LG terminals of the
programmable controller with a ground resistance of 100 ohms or less.
The following figure shows an example of the noise reduction measure:
Ground the shielded twisted pair cable on the encoder side (relay box). The following figure shows the wiring example:
(1) Provide a distance of 150mm or more away from I/O cables of the high voltage device such as a relay and inverter, regardless of whether inside or
outside the panel.
(2) For metal plumping, prevent a solenoid valve or inductive load from coexisting in the pipes. Where the separate distance from a high voltage line
cannot be provided sufficiently because of duct wiring and others, use the shield wire such as CVVS for the high voltage line.
(3) The distance between the encoder and the relay box should be as short as possible. Check that the voltages both in operation and at rest of the
encoder fall within the range of the rated voltage by using a measuring instrument such as a tester for the terminal block in the relay box because a
long distance from the high-speed counter module to the encoder can cause a voltage drop. If the voltage drop is high, take measures such as
replacing the wire to one with a larger wire size or using an encoder designed for 24VDC with a lower current consumption.
(4) Between the encoder and the shielded twisted pair cable, connect their shield wire together in the relay box. If the shield wire of the encoder to be used
is not grounded in the encoder, ground it in the relay box as the dotted line shows.

Example of wiring with a voltage output type encoder (5VDC)
Alphanumeric characters in the parentheses ( ) indicate the pin number of the channel 2.
Precautions
For the wiring with a voltage output type pulse generator, add the (3) Output resistance to the calculation formula below and
check that the input pulse current meets the specifications of input current. In addition, check the operation using an actual
module and device.
Input pulse current = ((1) - (2)) ((3) + (4))
Ex.
The calculation examples below are for obtaining the value of input pulse current to flow when the module is connected to a
24VDC output pulse generator with the output resistance of 1k. Assume that an input terminal of 24VDC is used as an input
resistance.
Input pulse current (Min) = (24V - 3.6V) (1k + 6.8k) = 2.62mA
Input pulse current (Max) = (24V - 2.6V) (1k + 6.8k) = 2.74mA
The input pulse current is within the range of 2.62mA (Min) to 2.74mA (Max), which meets the input specifications (ON current
of input: 2 to 5mA).
(1) Output voltage
(2) Input circuit voltage drop
(3) Output resistance
(4) Input resistance (Use a terminal that meets the specifications of input current as an input resistance.)
