NOTICE
The current rating differs for a motor with variable pole pitches differs from a standard motor.
Check the maximum current of the motor before selecting the drive capacity. Only switch motor poles when the motor is
stopped. Switching between motor during run will trigger overcurrent protection circuitry or result in overvoltage from
regeneration, and the motor will simply coast to stop.
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.
Never lift the drive up while the cover is removed.
This can damage the terminal board and other components.
