Mitsubishi Inverter FR-F700P Series : FR-F720P-3.7K

FR-F700P

Features Series

• Great CO2 emission reduction with energy-saving drive.         

Optimum excitation control continuously adjusts 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

• 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 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 live 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.
