DIN rail installation

You can do it by using the optional DIN rail attachment (FR-DU01/02). More Details >>

Protective functions

When the protective function works, the inverter is stopped (output shutoff) by the RDY signal. More Details >>

Pre-excitation, zero-speed control, and servo lock

Pre-excitation is the process to control current while a motor is stopped so that motor torque can be generated immediately. There are two methods for this p... More Details >>

Influence on leakage current

Since the converter in the high power factor converter section performs PWM switching, the leakage current increases to the same level as the general-purpose... More Details >>

What happens if the supplied reactor and outside box are not used?

Harmonics cannot be suppressed (controlled) correctly and noise cannot be removed. Be sure to connect the supplied reactor and outside box to the inverter. More Details >>

The outline dimensions of the FR-E520-7.5K are 180W×260H×170D. More Details >>

Stall mode

Since the stall prevention function works during acceleration and the inverter does not reach the commanded speed, set Pr.156 (Stall prevention operation sel... More Details >>

Durability in multi-speed setting
