Speed control range

Many geared motors cannot continuously operate at low speed (for example, slower than 6 Hz) due to grease viscosity.If the motor you are using is of this typ... More Details >>

Operation panel

Be sure to use the FR-E5P to mount the operation panel.This is because the board is bare on the back of the operation panel and a dedicated connector is requ... 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 >>

Notes when inverter capacity is larger than motor capacity

When using one-rank-higher inverter, as you mention, you need to care about the setting of the electronic thermal O/L relay.Setting the electronic thermal O/... More Details >>

Installing parameter unit outside control panel

You can install the operation panel FR-DU04 (or parameter unit FR-PU04) on the enclosure surface by connecting it with the inverter via a cable.To do this, d... More Details >>

Brake resistor

Connecting the brake resistor allows for quick deceleration because the regenerative power is processed. (The brake torque increases.)Therefore, when an exte... More Details >>

Selection

Refer to the following points.For fan pump -> Square torqueFor general-purpose machine (for example, transport, elevation) -> Constant-torque type More Details >>

Separation of operation panel

The operation panel of the FR-S500 is not detachable.For the FR-S500-○○K-R (compatible with RS-485 communication), you can install the FR-PU04 on the enclosu... More Details >>

Frequency display deviation

If you are using an external VR, influence by noise is probable.Setting Pr.74 (Input filter time constant) to a higher value stabilizes the frequency command... 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 >>
