2.1 Section Safety
NOTICE
Observe proper electrostatic discharge (ESD) procedures when
handling the drive.
Failure to comply could result in ESD damage to the drive circuitry.
Prevent foreign matter such as metal shavings or wire clippings
2
from falling into the drive during drive installation and project
construction.
Failure to comply could result in damage to the drive.
Place a temporary cover over the top during installation. Be sure to
remove the temporary cover before start-up, as the cover will
reduce ventilation and cause the unit to overheat.
It may be difficult to perform maintenance on the cooling fans
of drives installed in a vertical row inside an enclosure.
Ensure adequate spacing at the top of the drive to perform cooling
fan replacement when required.
Operating the drive in the low-speed range diminishes the
cooling effects, increases motor temperature, and may lead to
motor damage by overheating.
Reduce the motor torque in the low-speed range whenever using a
non-Yaskawa motor. If 100% torque is required continuously at low
speed, consider using a special drive or vector motor. Select a motor
that is compatible with the required load torque and operating speed
range.
Do not operate motors above the maximum rated RPM.
Failure to comply may lead to bearing or other mechanical motor
failures.
