Servomotor Installation Conditions - Omron OMNUC G5 Series User Manual

Ambient Temperature Control
Operation in an environment in which there is minimal temperature rise is recommended to
maintain a high level of reliability.
When the drive is installed in a closed space, such as a box, the ambient temperature may rise
due to temperature rise in each unit. Use a fan or air conditioner to prevent the drive's ambient
temperature from exceeding 55
Drive surface temperatures may rise to as much as 30
heat-resistant materials for wiring, and provide a distance from any devices or wiring that are
sensitive to heat.
The service life of a Servo Drive is largely determined by the ambient temperature around the
internal electrolytic capacitors. When an electrolytic capacitor reaches its limit, electrostatic
capacity drops and internal resistance increases. This leads to overvoltage errors, malfunctioning
due to noise, and damage to individual elements.
If a drive is always operated at the ambient temperature of 55
rated torque and rated rotation speed, its life is expected to be approx. 28,000 hours (excluding
the axial-flow fan). A drop of 10
drive.
Keeping Foreign Objects Out of Units
Place a cover over the drive or take other preventative measures to prevent foreign objects, such
as drill filings, from getting into the drive during installation. Be sure to remove the cover after
installation is complete. If the cover is left on during operation, drive's heat dissipation is blocked,
which may result in malfunction.
Take measures during installation and operation to prevent foreign objects such as metal
particles, oil, machining oil, dust, or water from getting inside of the drives.

Servomotor Installation Conditions

Environment Operating Conditions
The environment in which the motor is operated must meet the following conditions. Operating the
motor outside of the following ranges may result in malfunction of the motor.
Ambient operating temperature: 0 to 40°C
Operating humidity: 85% max. (with no condensation)
Operating atmosphere: No corrosive gases.
*1. The ambient operating temperature is the temperature at a point 5 cm from the motor.
Impact and Load
The motor is resistant to impacts of up to 98
2
m/s . Do not apply heavy impacts or loads
during transport, installation, or removal of
the motor.
When transporting the motor, hold the motor
body itself. And do not hold the encoder,
cable, or connector areas. Failure to follow
this guideline may result in damaging the
motor.
Always use a pulley remover to remove
pulleys, couplings, or other objects from the
shaft.
After assembly, secure cables so that there is no impact or load placed on the cable outlet.
