Long motor wiring

When you use a long wire between the inverter and motor, pay attention to the following: 1. Since the voltage supplied to the motor terminal is reduced due t... More Details >>

Inverter signal input speed

There is a 10 ms delay after the inverter recognizes the start command (STF OR STR) before it starts decelerating. The delay is 10 ms. A delay of 100 ms is i... More Details >>

Multi-speed operation

Use the first contact (relay) for the forward (or reverse) rotation between the terminals STF and SD. Use the second contact (relay) for the high-speed comma... More Details >>

Brake unit selection

Since the FR-A540-0.75K has a brake transistor for resistor regenerative driving inside the inverter, you do not need to use BU. Just remove the jumper from ... 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 >>
