5-3-9 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 environment 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 environment
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 needed 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.
