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 >>

Cycle operation mode, continuous operation mode, torque characteristic selection

When using a motor with an encoder by performing auto tuning, you need to choose the operation mode or continuous operation mode depending on the application... More Details >>

Angular velocity change control

The inverter itself does not have a function to detect the rotation angle and change the velocity accordingly. Therefore, to implement required control, it i... More Details >>

Automatic restart after instantaneous power failure

The inverter has the automatic restart after instantaneous power failure function. By setting Pr.61 to other than "9999", the encoder detects the speed of th... More Details >>

Unwinding using vector inverter

1. Torque control automatically adjust the speed so that the instructed torque value is maintained. This means that the speed is not controlled. (However, yo... More Details >>

Operation under torque limit in the speed control mode

Under a 50% torque limit, if the commanded speed (50 Hz in your example) cannot be achieved without torque exceeding 50%, since the torque does not exceed th... More Details >>

Difference from general-purpose inverter

While the inverter uses open-loop (V/F) control, it uses semi-closed loop vector control (constant current control). This enables output of stable torque esp... 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 >>

Geared motor

We do not offer a geared motor. More Details >>

Reusing parameter units

You cannot reuse the parameter unit (FR-PU01) for the FREQROL-Z series, the parameter unit (FR-PU02) for the FREQROL-A200 and A100 series, and the parameter ... More Details >>
