About this Manual:
The CQM1 is a compact, high-speed Programmable Controller (PC) designed for advanced control
operations in systems requiring from 16 to 256 I/O points per PC. There are two manuals describing the
setup and operation of the CQM1: The
CQM1 Operation Manual (this manual) and the CQM1 Program-
ming Manual
. Also available is the CQM1-series Dedicated I/O Units Operation Manual .
This manual describes the system configuration and installation of the CQM1 and provides an basic
explanation of operating procedures for the Programming Consoles and introduces the capabilities of the
Ladder Support Software (LSS) and SYSMAC Support Software (SSS). Read this manual first to acquaint
yourself with the CQM1.
The
CQM1 Programming Manual provides detailed descriptions of the CQM1’s programming functions.
The
Ladder Support Software Operation Manual and the SYSMAC Support Software Operation Manual:
C-series PCs
provides descriptions of LSS and SSS operations for the CQM1 and C-series PCs. Use
Version-3 LSS or a later version for CQM1 operation.
Please read this manual carefully and be sure you understand the information provide before attempting
to install and operate the CQM1.
Section 1 gives a brief overview of the steps involved in developing of a CQM1 System, describes the
possible system configurations, and describes the CQM1’s special features and functions.
Section 2 describes the Units that go together to create a CQM1 PC and provides information on switch
settings, installation, and hardware maintenance. Technical specifications of the Units are also provided.
Section 3 describes LSS/SSS capabilities, how to connect the Programming Console, and how to per-
form the various Programming Console operations.
Section 4 describes how to diagnose and correct the hardware and software errors that can occur during
PC operation.
The Appendix provides tables of CQM1 Units and related products.
WARNING Failure to read and understand the information provided in this manual may result in
personal injury or death, damage to the product, or product failure. Please read each
section in its entirety and be sure you understand the information provided in the section
and related sections before attempting any of the procedures or operations given.

1 Intended Audience
This manual is intended for the following personnel, who must also have knowl-
edge of electrical systems (an electrical engineer or the equivalent).
•Personnel in charge of installing FA systems.
•Personnel in charge of designing FA systems.
•Personnel in charge of managing FA systems and facilities.
2 General Precautions
The user must operate the product according to the performance specifications
described in the operation manuals.
Before using the product under conditions which are not described in the manual
or applying the product to nuclear control systems, railroad systems, aviation
systems, vehicles, combustion systems, medical equipment, amusement
machines, safety equipment, and other systems, machines, and equipment that
may have a serious influence on lives and property if used improperly, consult
your OMRON representative.
Make sure that the ratings and performance characteristics of the product are
sufficient for the systems, machines, and equipment, and be sure to provide the
systems, machines, and equipment with double safety mechanisms.
This manual provides information for programming and operating the Unit. Be
sure to read this manual before attempting to use the Unit and keep this manual
close at hand for reference during operation.
WARNING It is extremely important that a PC and all PC Units be used for the specified
purpose and under the specified conditions, especially in applications that can
directly or indirectly affect human life. You must consult with your OMRON
representative before applying a PC System to the above-mentioned
applications.
3 Safety Precautions
WARNING Do not attempt to take any Unit apart while the power is being supplied. Doing so
may result in electric shock.
WARNING Do not touch any of the terminals while the power is being supplied. Doing so
may result in electric shock.
WARNING Do not attempt to disassemble, repair, or modify any Units. Any attempt to do so
may result in malfunction, fire, or electric shock.
Caution Tighten the screws on the terminal block of the AC Power Supply Unit to the
torque specified in the manual. Loose screws may result in burning or malfunc-

Caution The operating environment of the PC System can have a large effect on the lon-
gevity and reliability of the system. Improper operating environments can lead to
malfunction, failure, and other unforeseeable problems with the PC System. Be
sure that the operating environment is within the specified conditions at installa-
tion and remains within the specified conditions during the life of the system.
5 Application Precautions
Observe the following precautions when using the PC System.
WARNING Always heed these precautions. Failure to abide by the following precautions
could lead to serious or possibly fatal injury.
•Always connect to a ground of 100 Ωor less when installing the Units. Not con-
necting to a ground of 100 Ωor less may result in electric shock.
•Always turn OFF the power supply to the PC before attempting any of the fol-
lowing. Not turning OFF the power supply may result in malfunction or electric
shock.
•Mounting or dismounting Power Supply Units, I/O Units, CPU Units,
Memory Cassettes, or any other Units.
•Assembling the Units.
•Setting DIP switches or rotary switches.
•Connecting or wiring the cables.
•Connecting or disconnecting the connectors.
Caution Failure to abide by the following precautions could lead to faulty operation of the
PC or the system, or could damage the PC or PC Units. Always heed these pre-
cautions.
•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.
•Interlock circuits, limit circuits, and similar safety measures in external circuits
(i.e., not in the Programmable Controller) must be provided by the customer.
•Always use the power supply voltage specified in the manual. An incorrect volt-
age 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.
