Mitsubishi FR-F700PJ Series
Air conditioning inverter
Features
Suitable for both the general-purpose motor and the IPM motor
- 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. (Compatible with the MM-EF series IPM motors.)
Environmentally friendly
- Power factor improving DC reactor, common mode choke (line noise filter), capacitive filter (radio noise filter) are all essential for air conditioning applications, and all of these are included in the Filterpack. The inverter with Filterpack is also available.
The wiring with different options is no longer required. - Less wiring and smaller space is required when Filterpack is used. Filterpack also enables compliance with the harmonic suppression guideline, the architectural standard specifications (electrical installation), and the architectural standard specifications (machinery installation) (2010 revisions) in Japan.
Easy-to-use
- The following functions provide the ideal operation for fans and pumps (PID control, Optimum excitation control, regeneration avoidance, and automatic restart after instantaneous power failure).
Improved reliability and easy maintenance
- Spring clamp terminals provide high reliability and easy wiring.
- The lives of the cooling fan and capacitor have been extended.
- Using the self-diagnosis function, the component life warning can be output and the degree of deterioration can be monitored to prevent malfunction.

*1: 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 becomes lower when a motor decelerates from a speed higher than the rated speed.When the regenerative power is large, use a braking option.
