Torque control

Torque control cannot be performed with the FR-E700 series. It is available with the FR-A700 and FR-V500 series. More Details >>

Vector motor

The constant-torque motor and vector motor are the induction motors, which consist of the stator core, gap, and rotor core. For the constant-torque motor, th... More Details >>

Relationship between frequency and load current

If the load is heavy and the output current is higher than the control value, you can adjust Pr.22 (Stall prevention operation level) to trigger the stall pr... More Details >>

Faults history upon power failure

When an instantaneous power failure of 100 msec or longer occurs, the inverter is reset* and it is not recognized as a fault. Since it is not recognized as a... 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 >>

Connecting multiple inverters to single high power factor converter

Up to 6 units. If you connect 7 or more inverters, the permissible output of control signals is exceeded. Be sure to use a high power factor converter with t... More Details >>

Harmonic suppression guidelines for power supply

Since the high power factor converter uses the self-excitation three-phase bridge (voltage type PWM control) circuit configuration (type), the conversion coe... More Details >>
