5-10 Environment and Facilities for Installation

The Hybrid Servo Controller is a device for electronic components. Detailed descriptions of the
environment suitable for its operation can be found in the specifications. If the listed regulations cannot
be followed for any reason, there must be corresponding remedial measures or contingency solutions.
1. To prevent vibration, anti-vibration spacer is the last choice. The vibration tolerance must
be within the specification. The vibration effect is equal to the mechanical stress and it
cannot occur frequently, continuously or repeatedly to prevent damaging AC motor drive.
2. Store in a clean and dry location free from corrosive fumes/dust to prevent rustiness, poor
contact. It also may cause short by low insulation in a humid location. The solution is to
use both paint and dust-proof. For particular occasion, use the enclosure with whole-seal
structure.
3. The ambient temperature must be just right. If the temperature is too high or too low, the
lifetime and action reliability of electronic components will be affected. For semiconductor
devices, once the conditions exceed the rated values, consequences associated with
"damage" are expected. As a result, in addition to providing cooler and shades that block
the direct sunlight that are aimed to achieve required ambient temperature, it is also
necessary to perform cleaning and spot check the air filter in the storage tray of Hybrid
Servo Controller and the angle of cooling fan. Moreover, the microcomputer may not work
at extremely temperature, space heater is required for machines that are installed and
operated in cold regions.
4. Avoid moisture and occurrence of condensation. If the Hybrid Servo Controller is expected
to be shut down for an extended period of time, be careful not to let condensation happen,
once the air conditioning is turned off. It is also preferred that the cooling equipment in the
electrical room can also work as a dehumidifier.
