FR-HC/FR-HC2

No, it cannot. Use the FR-HC2 dedicated reactor and outside box. More Details >>

Which motors can I use with the inverter?

You can use general-purpose three-phase induction motors.You can also use geared motors if the motor itself is an induction motor.Synchronous motors are not ... More Details >>

Common terminals of control circuit

If you ground the common terminals of the control circuit, it is connected with the inverter's earthing and the inverter's noise may be input to the control ... More Details >>

Frequency misalignment at current input

It seems that calibration of the current input is slightly incorrect.By using Pr.904 (Frequency setting current bias) and Pr.905 (Gain), you can calibrate th... More Details >>

Frequency adjustment using potentiometer

Since the inverter is initially set to 0 Hz for 0 V and 60 Hz for 5 V, you can calculate the frequency for a certain voltage value. The equation is "Output f... More Details >>

Current increase at motor stop

If the current increases when the motor stops under V/F control (at low speed under a light load), the motor is considered to be in the overexcitation state.... More Details >>

Speed adjustment of multiple inverters using variable resistor

You can connect up to three inverters in parallel to an external variable resistor. Refer to the figure below for a connection example. By setting parameters... More Details >>

Input power supply circuit breaker

When using a motor circuit breaker, the rated current of the motor circuit breaker to use must be equal to or higher than the rated current of the circuit br... More Details >>
