Frequency setting

Even though the maximum frequency setting is changed using CC-Link, the running frequency is not changed. By writing the set frequency to the remote register... More Details >>

Remote operation of the inverter

The wiring length of the start signal (STF etc.) is 30 m or less. The circuit voltage of the control input signals (terminal STF etc.) is 24 VDC and the volt... More Details >>

Inverter UL and CSA standard product document

The certificate of the standard product is managed by the branch office. Please ask the nearest branch office. More Details >>

Wire length between inverter and motor

1. Wiring length between the inverter and the motor should be 500 m or less. For 0.75 kW or lower motors, the following relationship is true: Capacity... 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 >>

Inverter with one-rank higher capacity

An inverter with one-rank higher capacity is often used when a high torque is required for a short period of time. (Examples)- When rapid acceleration/decele... More Details >>

I want to shorten deceleration time of small capacity motor

You can use an inverter with a larger capacity than the motor. You cannot connect a brake resistor to the FR-E520-0.1K and 0.2K. With the FR-E520-0.1K or 0.2... More Details >>

Inverter operation against power supply voltage drop

Depending on the load current, undervoltage protection (UVT) or instantaneous power failure protection (IPF) is triggered to shut off the inverter output, an... More Details >>

Connection with pole change motor

Since the inverter allows for changing speed, fix the number of poles when using the pole change motor. It is recommended to fix the number of poles to four ... More Details >>
