Surge voltage of 400 V motor
To upgrade the existing facilities, what is necessary in addition to the inverter for when 400 V motor and inverter are used.
Is there possibility of motor burnout since the motor is not upgraded this time?

Answer
When the wire between the 400 V inverter and motor is long (20 m or longer), surge voltage occurs momentarily. This voltage is as two or more times as the DC voltages converted by the inverter (400 VAC × √2 = 565 VDC), and is 1000 VDC or higher.
Since this voltage can deteriorate insulation of the motor:
1． Use an insulation-enhanced motor.
2． Attach the surge voltage suppression filter (FR-ASF-H).
Consider the above countermeasures.
