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 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 >>

Countermeasure against inverter noise

You can attach the following filters to the inverter input side:- Line noise filter (FR-BLF, FR-BSF01)- Radio noise filter (FR-BIF) 　While it is a good idea ... More Details >>

Advanced magnetic flux vector control

Yes. Set Pr.89 (Speed control gain) to "0". More Details >>

Coasting to stop method

Use Pr.17 (Input terminal assignment) to assign MRS to the terminals DI1, DI2, and DI3. More Details >>

External thermal overheat

Take the following countermeasure:1. If the thermal trips in low-speed operation, trips can be avoided, depending on the external thermal relay operation cha... More Details >>

Stop-on-contact control

1. You can implement stop-on-contact.2. When implementing stop-on-contact, use the inverter to decelerate the motors to reduce the impact upon stop-on-contac... More Details >>

FR-HC/FR-HC2

No, it cannot. Use the FR-HC2 dedicated reactor and outside box. More Details >>

FR Configurator2

Output current: Because the filter, effective value of the output current displayed on the operation panel, is included, the momentary fluctuation is difficu... More Details >>
