Product Description
The Mitsubishi FR-A220-0.75K-UL, from the FREQROL FR-A2 series, is a 0.75 kW (1 HP) AC inverter drive for variable frequency motor control. It accepts 50/60 Hz input, outputs 0.2-400 Hz at 1.9 kVA/2.5A, and operates between -10C and 50C (storage: -20C to 65C) with up to 90% RH (non-condensing) in non-corrosive environments. This 200 VAC three-phase drive features 150% starting torque at 1 Hz (magnetic flux vector control) and offers manual/automatic torque boost.
Is Your Device Showing These Signs?
Mitsubishi FR-A220-0.75K-UL AC Inverter drives commonly exhibit faults related to overcurrent tripping, often stemming from IGBT failures or issues within the inverter power module. Parameter corruption within the EEPROM necessitates reprogramming to factory defaults or specific application settings. Capacitor degradation in the DC bus leads to undervoltage faults and impacts drive performance. Communication errors via RS485 or Modbus protocols require troubleshooting of wiring and network configurations. Cooling fan failures cause overheating and thermal overload faults, demanding immediate fan replacement to prevent damage.
