Cleaning and Maintenance
Perform the following cleaning procedures periodically to ensure the Programmable Multi-Axis Control-
ler is maintained in optimum operating condition.
• During daily cleaning, wipe off dust and dirt using a soft, dry cloth.
• If any dust or dirt remains even after wiping using 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 gum, vinyl, or tape that was left on for a long time. Remove
the smudges when cleaning.
The Programmable Multi-Axis Controller can deteriorate under adverse environmental conditions. Peri-
odic inspections are thus 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 will
be necessary in adverse environments.
Take immediate steps to correct the situation if any of the conditions in the following table are not met.

Correction
1
External power sup-
ply
Check for voltage fluctu-
ations at the power sup-
ply terminals.
The voltage must be
within the allowable volt-
age fluctuation range.
Take necessary steps to
bring the voltage of the
supplied power to within
the allowable voltage fluc-
tuation range.
2
Ambient environment Check the ambient tem-
perature.
(Inside the control panel
if the Controller is in a
control panel.)
0 to 45°C
Use a thermometer to
check the temperature and
ensure that the ambient
temperature remains within
the allowed range of 0 to
45°C.
Check the ambient
humidity. (Inside the con-
trol panel if the Controller
is in a control panel.)
Relative humidity must
be 10% to 95% with no
condensation.
Use a hygrometer to check
the humidity and ensure
that the ambient relative
humidity remains between
10% and 95%. Make sure
that no condensation forms
due to rapid changes in
temperature.
Check that the Controller
is not in direct sunlight.
Not in direct sunlight
Protect the Controller if
necessary.
Check for accumulation
of dirt, dust, salt, metal
powder, etc.
No accumulation
Clean and protect the Con-
troller if necessary.
