The inverter control power is also the same, the pole is not the same as the motor 6 or 4 pole can be used?
Can be used, but is being used in the motor replacement, you need to change the frequency conversion.
can use. But in the inverter "motor parameters" to be some changes. Such as the number of poles, rated current.
Can be used, their rated current is not the same, the need to use the inverter over-current overload protection and other parameters for the corresponding changes.
