System Design
If a driver is always operated at the ambient temperature of 55
°
C and with 100% output of the rated
torque and rated rotation speed, its limit is expected to be approx. 28,000 hours (excluding the
axial-flow fan). A drop of 10
°
C in the ambient temperature will double the expected limit for driver.
Keeping Foreign Objects Out of Units
Place a cover over the driver or take other preventative measures to prevent foreign objects, such
as drill filings, from getting into the driver during installation. Be sure to remove the cover after
installation is complete. If the cover is left on during operation, driver'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 drivers.
