CAUTION
NOTICE
1.1 Section Safety
Do not carry the drive by the front cover.
Failure to comply may cause the main body of the drive to fall, resulting in minor or moderate injury.
Observe proper electrostatic discharge procedures (ESD) when handling the drive and circuit boards.
Failure to comply may result in ESD damage to the drive circuitry.
A motor connected to a PWM drive may operate at a higher temperature than a utility-fed motor and the
operating speed range may reduce motor cooling capacity.
Ensure that the motor is suitable for drive duty and/or the motor service factor is adequate to accommodate the
additional heating with the intended operating conditions.

2.1 Section Safety
W ARNING
CAUTION
NOTICE
2.1 Section Safety
Fire Hazard
Provide sufficient cooling when installing the drive inside an enclosed panel or cabinet.
Failure to comply could result in overheating and fire.
When multiple drives are placed inside the same enclosure panel, install proper cooling to ensure air entering the
enclosure does not exceed 50 °C.
Crush Hazard
Do not carry the drive by the front cover.
Failure to comply may result in minor or moderate injury from the main body of the drive falling.
Observe proper electrostatic discharge (ESD) procedures when handling the drive.
Failure to comply could result in ESD damage to the drive circuitry.
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 motor 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 standard blower cooled 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.
The speed range for continuous operation differs according to the lubrication method and motor manufacturer.
If the motor is to be operated at a speed higher than the rated speed, consult with the manufacturer.
Continuously operating an oil-lubricated motor in the low-speed range may result in burning.
When the input voltage is 480 V or higher or the wiring distance is greater than 100 meters, pay special
attention to the motor insulation voltage or use a drive-rated motor.
Failure to comply could lead to motor winding failure.
The motor may require more acceleration torque with drive operation than with a commercial power supply.
Set a proper V/f pattern by checking the load torque characteristics of the machine to be used with the motor.
Do not use a drive for a single-phase motor.
Replace the motor with a three-phase motor.
If an oil-lubricated gearbox or speed reducer is used in the power transmission mechanism, oil lubrication will
be affected when the motor operates only in the low speed range.
The power transmission mechanism will make noise and experience problems with service life and durability if the
motor is operated at a speed higher than the rated speed.
