Cleaning and Maintenance
This section describes daily maintenance and the cleaning and inspection methods.
In order to use the functions of the Motion Controller in the best condition, please perform daily or reg-
ular inspections.
6-1-1
Cleaning
Perform the following cleaning procedures periodically to ensure the Motion Controller is maintained in
the best operating condition. Always turn OFF the power supply to the Motion Controller before per-
forming the cleaning procedures.
• Wipe off the dust or dirt on the front, top, or bottom of the Unit with a dry, soft cloth when doing daily
cleaning.
• If dust or dirt remains even after wiping with a soft, dry cloth, wipe over with a cloth that has been
wet with a sufficiently diluted detergent (2%) and wrung dry.
• Smudges may remain on the Unit from rubber, vinyl, or tape that was left on for a long time. Remove
the smudges when cleaning.
Precautions for Correct Use
Never use volatile solvents, such as paint thinner, benzene, or chemical wipes.

Periodic Inspections
Since Motion Controller elements can deteriorate under improper environmental conditions, periodic
inspections are required to ensure that the required conditions are being maintained.
Inspection is recommended at least once every six months to a year, but more frequent inspections
may be necessary depending on the ambient environment.
Take immediate steps to correct the situation if any of the conditions in the following table are not met.

Check for voltage fluctua-
tions at the power supply ter-
minals.
The voltage must be
within the allowable

Ambient
environ-
ment
Check the ambient tempera-
ture.

0 to 45°C Use a thermometer to check the tempera-
ture and ensure that the ambient tempera-
ture remains within the allowed range of 0 to
45°C.
Check the ambient humidity
.
*2
Relative humidity
must be 10% to
95% with no con-
densation.
Use a hygrometer to check the humidity and
ensure that the ambient operating humidity
remains between 10% and 90%.
Make sure that condensation does not occur
due to rapid changes in temperature.
Check that the Controller is
not in direct sunlight.
Not in direct sunlight Protect the Controller if necessary.
