Safety Precautions 3
• Locations subject to static electricity or other forms of noise
• Locations subject to strong electromagnetic fields
• Locations subject to possible exposure to radioactivity
• Locations close to power supplies
!Caution The operating environment of the FQM1 System can have a large effect on
the longevity and reliability of the system. Improper operating environments
can lead to malfunction, failure, and other unforeseeable problems with the
FQM1 System. Make sure that the operating environment is within the speci-
fied conditions at installation and remains within the specified conditions dur-
ing the life of the system.
3-2 Application Precautions
!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
Ω or less when installing the FQM1.
Not doing so may result in electric shock.
• Always connect to a ground of 100 Ω or less when short-circuiting the
functional ground and line ground terminals of the Power Supply Unit, in
particular.
• Always turn OFF the power supply to the FQM1 before attempting any of
the following. Not turning OFF the power supply may result in malfunction
or electric shock.
• Mounting or dismounting Power Supply Unit, Coordinator Module, Mo-
tion Control Module, and End Module
• Assembling the Modules
• Setting DIP 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 FQM1 or the system, or could damage the FQM1. Always heed these pre-
cautions.
• Always use the CX-Programmer (Programming Device for Windows) to
create new cyclic tasks and interrupt tasks.
• The user program and parameter area data in Coordinator Module and
Motion Control Modules is backed up in the built-in flash memory. Do not
turn OFF the power supply to the FQM1 while the user program or param-
eter area data is being transferred. The data will not be backed up if the
power is turned OFF.
• The FQM1 will start operating in RUN mode when the power is turned ON
with the default settings (i.e., if the operating mode at power ON (startup
mode) setting in the System Setup is disabled).
• Configure the external circuits so that the control power supply turns ON
after the power supply to the FQM1 turns ON. If the power is turned ON in
the opposite order, the built-in outputs and other outputs may momen-
tarily malfunction and the control outputs may temporarily not operate cor-
rectly.
