FREQROL-A200 AC Inverter Drive 7.5 kW – Mitsubishi FR-A220E-7.5K
The FR-A220E-7.5K is a three-phase AC variable frequency drive (“AC Variable Frequency Drive”) rated at 7.5 kW, belonging to the FREQROL-A200 series by Mitsubishi Electric. Designed for speed control of three-phase asynchronous motors in industrial and CNC machine tool applications, the FR-A220E-7.5K belongs to the 200 V voltage class (input 3~ 200–240 V AC, 50/60 Hz) and delivers a three-phase output at variable frequency and amplitude, typically between 0.5 and 400 Hz. The unit integrates V/f control logic and features digital and analogue I/O for interfacing with the CNC or machine PLC. It is available in multiple hardware revisions; some versions support the vector control option with encoder feedback (PG option).
The inverter converts the mains supply into a three-phase voltage with variable frequency and amplitude, enabling precise motor speed control. On a machine tool it manages spindle or auxiliary axis acceleration and deceleration ramps, provides thermal and overcurrent motor protection, and maintains stable rotation under varying load. A drive failure causes the immediate stop of the controlled spindle or axis, rendering the machine inoperable until the unit is replaced or repaired.
Mitsubishi Electric is one of the world’s leading manufacturers of industrial automation, motion control and power electronics. The FREQROL brand covers Mitsubishi’s inverter range, in production since the 1980s and continuously updated with the current FR-F800, FR-E800 and FR-A800 series. The FREQROL-A200 series (“FR-A220E”) is legacy / discontinued: no longer manufactured or officially supported, it is available only as used/surplus stock or through specialist repair services.
