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 >>

Vector inverter option

Just by adding this option, encoder pulses connected to the inverter or option are output.You can also divide the pulse train output. More Details >>

Inverter control power supply

To supply power via R1 and S1, 60 VA or higher is necessary for 22K or lower and 80 VA or higher is necessary for 30K to 55K.Note that the rush current of ap... More Details >>

Rotation ripple at low speed

The rotation ripple data for 1.5 kW is shown below.Drive unit: MD-CX520-1.5KMotor: MM-CF152Load: None (motor alone), carrier frequency: 2 kHz, wiring length:... More Details >>

I want to display the speed on an analog meter.

As the inverter does not display the speed in m/min, let us explain using the speed display in r/min. In this case, set Pr.52 to "6" (operation panel display... More Details >>

Encoder cable length restriction

If the cable length is longer than 100 m, speed may not be read correctly due to voltage drop and waveform deformation of the encoder signal. Therefore, use ... More Details >>

Auto tuning

Check if any device is connected to the inverter's external terminal.In particular, check if MRS and SD are short-circuited.If they are short-circuited, open... More Details >>
