We have a F04 UnderVoltage fault on a PowerFlex 400 drive, which does not want to reset. It was running normally for months.
We checked input voltage 3~ ok, input fuses ok.
What could be the problem? inside the drive? inner fuses?
Can it be repaired? by changing some electronic devices?
90 kw , PowerFlex 400, Fan & Pump Drive. 380 VAC, 3 PH. 170 Amps. 125 HP,Frame Size F, IP30 (NEMA 1 / UL Type 1). Fixed Keypad. RS485 (without Brake IGBT) Rockwell 22C-D170A103
Thank you
