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 >>

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 >>

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 >>

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 >>

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 >>

FR-CV

Use the FR-HC to suppress harmonics. It also supports power supply regenerative driving.The FR-CV and FR-RC are both power supply regeneration units.The diff... 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 >>

FR-A500 main circuit wire types

Since the UL standard defines to "Use copper wires (rated at 75?C)", we also recommend the same type of copper wire. 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 >>

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 >>
