Mitsubishi FR-F700P Series
Inverter for fans and pumps
Features
Great CO2 emission reduction with energy-saving drive
- Optimum excitation control continuously adjusts the excitation current to an optimum level to provide the highest motor efficiency leading to substantial energy savings.
- This series can drive both a general-purpose motor and an IPM motor. Switching between the two motor controls is simple—just a single parameter setting. (Initially, a general purpose motor could be used, then upgraded to an IPM motor without switching this inverter, leading to lower cost of equipment.)
Easy-to-use
- The following functions provide the ideal operation for fans and pumps: variable torque acceleration/deceleration patterns, PID control, commercial power supply switching, adjustable 5 points V/F, continuous operation at an instantaneous power failure, regeneration avoidance function, etc.
Environmentally friendly
- The newly developed built-in EMC filter reduces electromagnetic noise generated from the inverter.
Improved reliability and easy maintenance
- The lives of the cooling fan and capacitor have been extended.
- Using the self-diagnosis function, the part life warning can be output and the degree of deterioration can be monitored to prevent malfunction.
- The removable control terminal block and the cooling fan cassette make it easy to replace.

*1: FR-F740P-1.5K to 45K manufactured in January 2011 or later are compatible with the premium high-efficiency IPM motor MM-EFS series.
*2: Regenerative braking torque is the average short-time torque when a motor decelerates to a stop from the rated speed in the shortest time. (It varies with the motor loss.) It is not a continuous regenerative torque.
The average deceleration torque decreases when a motor decelerates from a speed higher than the rated speed.When the regenerative power is large, use a braking option..
