any error or when a severe failure alarm (FALS) instruction is executed.
As a countermeasure for such errors, external safety measures must be
provided to ensure safety in the system.
• The PC outputs may remain ON or OFF due to deposition or burning of
the output relays or destruction of the output transistors. As a countermeasure for such problems, external safety measures must be provided
to ensure safety in the system.
• When the 24-VDC output (service power supply to the PC) is overloaded
or short-circuited, the voltage may drop and result in the outputs being
turned OFF. As a countermeasure for such problems, external safety
measures must be provided to ensure safety in the system.
!WARNING Do not attempt to disassemble, repair, or modify any Units. Any attempt to do
so may result in malfunction, fire, or electric shock.
!WARNING Do not touch the Power Supply Unit while power is being supplied or immedi-
ately after power has been turned OFF. Doing so may result in burns.
!Caution Execute online edit only after confirming that no adverse effects will be
caused by extending the cycle time. Otherwise, the input signals may not be
readable.

the PC or the system, or could damage the PC or PC Units. Always heed
these precautions.
• Fail-safe measures must be taken by the customer to ensure safety in the
event of incorrect, missing, or abnormal signals caused by broken signal
lines, momentary power interruptions, or other causes.
• Fail-safe measures must be taken by the customer to ensure safety in the
event that outputs from Output Units remain ON as a result of internal circuit failures, which can occur in relays, transistors, and other elements.
• Always turn ON power to the PC before turning ON power to the control
system. If the PC power supply is turned ON after the control power supply, temporary errors may result in control system signals because the
output terminals on DC Output Units and other Units will momentarily turn
ON when power is turned ON to the PC.
• Do not turn OFF the power supply to the PC when data is being transferred. In particular, do not turn OFF the power supply when reading or
writing a Memory Card. Also, do not remove the Memory Card when the
BUSY indicator is lit. To remove a Memory Card, first press the memory
card power supply switch and then wait for the BUSY indicator to go out
before removing the Memory Card.
• If the I/O Hold Bit (SR 25212) is turned ON, the outputs from the PC will
not be turned OFF and will maintain their previous status when the PC is
switched from RUN or MONITOR mode to PROGRAM mode. Make sure
that the external loads will not produce dangerous conditions when this
occurs. (When operation stops for a fatal error, including those produced
with the FALS(07) instruction, all outputs from Output Unit will be turned
OFF and only the internal output status will be maintained.)
• Install the Units properly as specified in the operation manuals. Improper
installation of the Units may result in malfunction.
• Mount Units only after checking terminal blocks and connectors completely.
• When assembling the Units or mounting the end cover, be sure to lock
them securely as shown in the following illustrations. If they are not properly locked, desired functionality may not be achieved.
• Be sure to mount the end cover to the rightmost Unit.
• Be sure that all the mounting screws, terminal screws, and cable connector screws are tightened to the torque specified in the relevant manuals.
Incorrect tightening torque may result in malfunction.
• Be sure that the terminal blocks, Memory Units, expansion I/O cables,
and other items with locking devices are properly locked into place.
Improper locking may result in malfunction.
• Be sure to confirm the orientation and polarities when connecting terminal
blocks and connectors.
• Leave the label attached to the Unit when wiring. Removing the label may
result in malfunction if foreign matter enters the Unit.
• Remove the label after the completion of wiring to ensure proper heat dissipation. Leaving the label attached may result in malfunction.
• Wire all connections correctly.
• When supplying power at 200 to 240 V AC from a CQM1-PA216 Power
Supply Unit, always remove the metal jumper from the voltage selector
xx
Application Precautions 5
terminals. The product will be destroyed if 200 to 240 V AC is supplied
while the metal jumper is attached.
• A ground of 100
Ω or less must be installed when shorting the GR and LG
terminals on the Power Supply Unit.
• Use crimp terminals for wiring. Do not connect bare stranded wires
directly to terminals. Connection of bare stranded wires may result in
burning.
• Do not apply voltages to the Input Units in excess of the rated input voltage. Excess voltages may result in burning.
• Do not apply voltages or connect loads to the Output Units in excess of
the maximum switching capacity. Excess voltage or loads may result in
burning.
• Install external breakers and take other safety measures against short-circuiting in external wiring. Insufficient safety measures against short-circuiting may result in burning.
• Always use the power supply voltages specified in the operation manuals.
An incorrect voltage may result in malfunction or burning.
• Take appropriate measures to ensure that the specified power with the
rated voltage and frequency is supplied. Be particularly careful in places
where the power supply is unstable. An incorrect power supply may result
in malfunction.
• Disconnect the functional ground terminal when performing withstand
voltage tests. Not disconnecting the functional ground terminal may result
in burning.
• Check switch settings, the contents of the DM Area, and other preparations before starting operation. Starting operation without the proper settings or data may result in an unexpected operation.
• Check the user program for proper execution before actually running it on
the Unit. Not checking the program may result in an unexpected operation.
• Double-check all wiring and switch settings before turning ON the power
supply. Incorrect wiring may result in burning.
• Confirm that no adverse effect will occur in the system before attempting
any of the following. Not doing so may result in an unexpected operation.
• Changing the operating mode of the PC.
• Force-setting/force-resetting any bit in memory.
• Changing the present value of any word or any set value in memory.
• Before touching a Unit, be sure to first touch a grounded metallic object in
order to discharge any static build-up. Not doing so may result in malfunction or damage.
• Do not pull on the cables or bend the cables beyond their natural limit.
Doing either of these may break the cables.
• Do not place objects on top of the cables or other wiring lines. Doing so
may break the cables.
• Resume operation only after transferring to the new CPU Unit the contents of the DM Area, HR Area, and other data required for resuming
operation. Not doing so may result in an unexpected operation.
• Do not short the battery terminals or charge, disassemble, heat, or incinerate the battery. Do not subject the battery to strong shocks. Doing any
of these may result in leakage, rupture, heat generation, or ignition of the
battery. Dispose of any battery that has been dropped on the floor or oth-
xxi
Application Precautions 5
erwise subjected to excessive shock. Batteries that have been subjected
to shock may leak if they are used.
• UL standards required that batteries be replaced only by experienced
technicians. Do not allow unqualified persons to replace batteries.
• When replacing parts, be sure to confirm that the rating of a new part is
correct. Not doing so may result in malfunction or burning.
• When transporting or storing circuit boards, cover them in antistatic material to protect them from static electricity and maintain the proper storage
temperature.
• Do not touch circuit boards or the components mounted to them with your
bare hands. There are sharp leads and other parts on the boards that
may cause injury if handled improperly.
• Before touching a Unit or Board, be sure to first touch a grounded metallic
object to discharge any static build-up from your body. Not doing so may
result in malfunction or damage.
• Provide sufficient clearances around the Unit and other devices to ensure
proper heat dissipation. Do not cover the ventilation openings of the Unit.
• For wiring, use crimp terminals of the appropriate size as specified in relevant manuals.
• Do not allow metallic objects or conductive wires to enter the Unit.
• Set the operating settings of the Temperature Controller properly according to the system to be controlled.
• Provide appropriate safety measures, such as overheat prevention and
alarm systems, in separate circuits to ensure safety of the entire system
even when the Temperature Controller malfunctions.
• Allow at least 10 minutes after turning ON the Temperature Controller as
warmup time.
• Do not use thinner to clean the product. Use commercially available
cleaning alcohol.
• Mount the I/O Control Unit on the right of the CPU Block.
• When using Expansion I/O Blocks, configure the system so that the current consumptions for the CPU Block and each of the Expansion I/O
Blocks do not exceed the specified values, and that the total current consumption does not exceed the current capacity of the Power Supply Unit.
• Configure the system so that the number of Units in both the CPU Block
and Expansion I/O Blocks do not exceed the maximum number of connectable Units for the Block.

Conformance to EC Directives 6
6 Conformance to EC Directives
6-1 Applicable Directives
•EMC Directives
• Low Voltage Directive
6-2 Concepts
EMC Directives
OMRON devices that comply with EC Directives also conform to the related
EMC standards so that they can be more easily built into other devices or
machines. The actual products have been checked for conformity to EMC
standards (see the following note). Whether the products conform to the standards in the system used by the customer, however, must be checked by the
customer.
EMC-related performance of the OMRON devices that comply with EC Directives will vary depending on the configuration, wiring, and other conditions of
the equipment or control panel in which the OMRON devices are installed.
The customer must, therefore, perform final checks to confirm that devices
and the overall machine conform to EMC standards.
Note Applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility): EN61131-2
EMI (Electromagnetic Interference): EN61000-6-4
(Radiated emission: 10-m regulations)
Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 V AC or 75 to
1,500 V DC meet the required safety standards for the PC (EN61131-2).
6-3 Conformance to EC Directives
The CQM1H-series PCs comply with EC Directives. To ensure that the
machine or device in which a CQM1H-series PC is used complies with EC
directives, the PC must be installed as follows:
1, 2, 3...
1. The PC must be installed within a control panel.
2. Reinforced insulation or double insulation must be used for the DC power
supplies used for the communications and I/O power supplies.
3. PCs complying with EC Directives also conform to the Common Emission
Standard (EN61000-6-4). When a PC is built into a machine, however,
noise can be generated by switching devices using relay outputs and
cause the overall machine to fail to meet the Standards. If this occurs,
surge killers must be connected or other measures taken external to the
PC.
The following methods represent typical methods for reducing noise, and
may not be sufficient in all cases. Required countermeasures will vary depending on the devices connected to the control panel, wiring, the configuration of the system, and other conditions.
6-4 Relay Output Noise Reduction Methods
The CQM1H-series PCs conforms to the Common Emission Standards
(EN61000-6-4) of the EMC Directives. However, noise generated by relay out-
xxiii
Conformance to EC Directives 6
put switching may not satisfy these Standards. In such a case, a noise filter
must be connected to the load side or other appropriate countermeasures
must be provided external to the PC.
Countermeasures taken to satisfy the standards vary depending on the
devices on the load side, wiring, configuration of machines, etc. Following are
examples of countermeasures for reducing the generated noise.
Countermeasures
Refer to EN61000-6-4 for more details.
Countermeasures are not required if the frequency of load switching for the
whole system including the PC is less than 5 times per minute.
Countermeasures are required if the frequency of load switching for the whole
system including the PC is 5 times or more per minute.
Countermeasure Examples
When switching an inductive load, connect a surge protector, diodes, etc., in
parallel with the load or contact as shown below.
Circuit Current Characteristic Required element
AC DC
Yes Yes If the load is a relay or solenoid, there is
a time lag between the moment the
circuit is opened and the moment the
load is reset.
If the supply voltage is 24 or 48 V, insert
the surge protector in parallel with the
load. If the supply voltage is 100 to 200
V, insert the surge protector between
the contacts.
The capacitance of the capacitor must
be 1 to 0.5 µF per contact current of
1 A and resistance of the resistor must
be 0.5 to 1 Ω per contact voltage of 1 V.
These values, however, vary with the
load and the characteristics of the
relay. Decide these values from testing,
and take into consideration that the
capacitance suppresses spark
discharge when the contacts are
separated and the resistance limits the
current that flows into the load when
the circuit is closed again.
The dielectric strength of the capacitor
must be 200 to 300 V. If the circuit is an
AC circuit, use a capacitor with no
polarity.
No Yes The diode connected in parallel with
the load changes energy accumulated
by the coil into a current, which then
flows into the coil so that the current will
be converted into Joule heat by the
resistance of the inductive load.
This time lag, between the moment the
circuit is opened and the moment the
load is reset, caused by this method is
longer than that caused by the CR
method.
The reversed dielectric strength value
of the diode must be at least 10 times
as large as the circuit voltage value.
The forward current of the diode must
be the same as or larger than the load
current.
The reversed dielectric strength value
of the diode may be two to three times
larger than the supply voltage if the
surge protector is applied to electronic
circuits with low circuit voltages.
Yes Yes The varistor method prevents the
imposition of high voltage between the
contacts by using the constant voltage
characteristic of the varistor. There is
time lag between the moment the
circuit is opened and the moment the
load is reset.
If the supply voltage is 24 or 48 V, insert
the varistor in parallel with the load. If
the supply voltage is 100 to 200 V,
insert the varistor between the
contacts.

1-1 Features
The CQM1H is a compact Programmable Controller (PC) that supports communications and other advanced functions. It is a package-type PC that is
mounted to DIN Track to control small to medium-size machines.
A flexible system configuration is enhanced by serial communications with a
protocol macro function, user-installed boards called Inner Boards, network
communications, a wide range of monitoring and setting methods, higher
speed, and larger capacity. These features enable added-value machine control.
• Mount up to two Inner Boards to add communications or control functions.
Communications Functions: Serial Communications Board
Control Functions: High-speed Counter Board, Pulse I/O Board, Absolute
Encoder Interface Board, Analog Setting Board, and Analog I/O Board
• Mount a Controller Link Unit to connect to a Controller Link Network.
• Connect simultaneously to both a Programming Device and a Programmable Terminal (PT).
• Obtain higher speed and capacity in comparison to the CQM1: 1.25 times
faster, twice the program capacity (15.2 Kwords), twice the I/O capacity
(512 points), and twice the data memory capacity (12 Kwords).
• Use new instructions.
• Maintain compatibility with previous models of PC.
Flexible System
Configuration
The CQM1H does not require a Backplane and is constructed by connecting
Units via connectors on the sides of the Units, allowing flexible system configuration. The CPU Unit contains 16 built-in DC input points. Two Inner Boards
can be mounted in the CPU Unit. One Controller Link Unit (a Communications
Unit) and a combined maximum of eleven I/O Units and Dedicated I/O Units
can also be connected. If an Expansion I/O Block is used, a maximum of 16
Units can be connected. (See 1-2-1 Basic Configuration.)
Note 1. The CQM1H is mounted to DIN Track.
2. Only the CQM1H-CPU51/61 CPU Units support Inner Boards and the
Controller Link Unit.
Higher Speeds and
Greater Capacity
Execution times have been reduced to 0.375
µs for the LOAD instruction
(from 0.50
µs for the CQM1), to 17.7 µs for the MOVE instruction (from
23.5
µs) and to 0.70 ms for overseeing (from 0.80 ms), reducing the total
cycle time by approximately 25%.
• The program capacity, the I/O capacity, and the data memory capacity
have all been approximately doubled. The program capacity has been
increased to 15.2 Kwords (from 7.2 Kwords for the CQM1); the I/O capac-
Units assembled via connectors on their sides.

ity, to 512 points (from 256 points); and the data memory capacity, to
6 Kwords of DM and 6 Kwords of EM (from 6 Kwords of DM only).
• A 16-Kword Memory Cassette can be mounted in the CQM1H to handle
large user programs or more data. These features ensure a higher level
of machine control and greater ease of use.
Increased Functionality
with Inner Boards
The CQM1H features Inner Boards that allow serial communications, multipoint high-speed counter (rotary encoder) inputs, simple positioning (trapezoidal acceleration/deceleration pulse outputs), speed changes, PWM (variable
duty-factor pulse) outputs, absolute rotary encoder inputs, analog I/O (4
inputs, 2 outputs), and analog settings.
A Serial Communications Board, High-speed Counter Board, Pulse I/O
Board, Absolute Encoder Interface Board, Analog I/O Board, and Analog Setting Board are available. These Inner Boards can be combined, mounted and
used as required for the machine being controlled. (There are mounting
restrictions for some of the Inner Boards.)
Note The CPU Unit also provides16 built-in inputs, as well as high-speed counter
and input interrupt functions. Pulse outputs are also supported using a standard Transistor Output Unit.

Better Connections to
Machine Components with
Serial Communications
Connections can be easily made to general-purpose machine components
and dedicated controllers. The Serial Communications Board (an Inner
Board) supports a protocol macro function. You can create macros for protocols according to the communications specifications of the external device,
allowing data transfers with general-purpose devices to be executed with a
single PMCR instruction. Essentially any device with a serial port can be communicated with, such as temperature controllers, bar-code readers, and dedicated numeric controllers.
Distributed Control with
Compact PCs with
Network
Communications
A Controller Link Unit can be included in the CQM1H. Data can be exchanged
between several PCs using a Controller Link Network. Data links are supported to create shared data areas and message communications are supported to enable sending required data and commands using network
communications instructions. The Controller Link Network can be easily constructed using twisted-pair cable. Data exchange is also supported with
C200HX/HG/HE, CS-series, CVM1, and CV-series PCs, as well as with personal computers.
Note Data links can be created with another CQM1H or with a CQM1, CPM1,
CPM1A, CPM2A, CPM2C, SRM1, C200HX/HG/HE, or C200HS simply by
making a 1:1 connection between the built-in RS-232C ports in the CPU
Units.

CQM1H.)
A Wide Range of HMI
Monitoring and Setting
Methods
Programming Devices and Programmable Terminals (PTs) can be connected
to up to four ports, two ports on the CPU Unit and two ports on a Serial Communications Board. It is thus possible to set up and monitor machine control
from a PT while monitoring or programming from a Programming Console or a
personal computer.
