The FR-A700 was the machine-drive member of Mitsubishi Electric’s FREQROL 700 generation, introduced in 2006, discontinued in 2016 and replaced by the FR-A800. The control set is the high-function one: V/F, Advanced magnetic flux vector and Real sensorless vector control as standard, with closed-loop vector control available once an FR-A7AP or FR-A7AL encoder option is fitted.
Unlike the FR-A800 it publishes a single rating rather than four selectable duty settings, 150 per cent for 60 s across the whole range. Output frequency reaches 400 Hz, falling to 120 Hz under Real sensorless vector and vector control. The model number is direct: FR-A720 for 200 V, FR-A740 for 400 V, then the inverter capacity in kilowatts with a trailing K.
Mitsubishi calls the FR-A800 a suitable drop in replacement in most cases, but flags design and dimensional changes above 125 HP at 200 V and 450 HP at 400 V, so a large-frame swap is not automatic.
Real sensorless vector control as standard, with closed-loop vector control once an FR-A7AP or FR-A7AL encoder option is fitted
Advanced magnetic flux vector control and V/F control also selectable
Starting torque of 200% at 0.3 Hz on the 0.4K to 3.7K frames, 150% at 0.3 Hz from 5.5K upward
One overload rating across the whole range: 150% for 60 s and 200% for 3 s at 50 degrees C
Applicable motor capacity 0.4 kW to 90 kW at 200 V, 0.4 kW to 500 kW at 400 V
Torque limit adjustable 0 to 400%, with an adjustable 5 point V/F pattern and linear or S-pattern ramps

The larger 400 V ratings FR-A740-280K to FR-A740-500K are not listed above; contact us with your model number and we will confirm the details for those frames. Rated current figures in brackets apply when Pr.72 PWM frequency selection is set higher than 2 kHz, and rated capacity assumes an output voltage of 220 V on the 200 V class or 440 V on the 400 V class.
