NOTICE
When the input voltage is 440 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.
Motor vibration may increase when operating a machine in variable-speed mode, if that machine previously
operated at a constant speed.
Install vibration-proof rubber on the motor base or use the frequency jump function to skip a frequency resonating the
machine.
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.
The rated input current of submersible motors is higher than the rated input current of standard motors.
Select an appropriate drive according to its rated output current. When the distance between the motor and drive is long,
use a cable thick enough to connect the motor to the drive to prevent motor torque reduction.
When using an explosion-proof motor, it must be subject to an explosion-proof test in conjunction with the drive.
This is also applicable when an existing explosion-proof motor is to be operated with the drive. Since the drive itself is
not explosion-proof, always install it in a safe place.
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.
