Additional Information
For Drives of 100 V or 200 V with a capacity of 750 W max., the specifications for operating ambient
temperature depend on the Drive (A, B, and C) when the clearance between Drives is 1 mm.
•
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°C.
•
Drive surface temperatures may rise to as much as 30°C above the ambient temperature. Use
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°C and with a 100% output of the rated
torque and rated speed, its life is expected to be approximately 28,000 hours (excluding the axial-flow
fan). A drop of 10°C in the ambient temperature will double the expected life of the drive.
•
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 Servo Drives.
Drive A: 0 to 50°C
Drive B: 0 to 40°C
Drive C: 0 to 45°C
