Simple torque control using stall prevention function

Basically, torque control cannot be performed. Instead, control speed to adjust the winding torque. It is possible to use the current limit function to preve... More Details >>

Direct driven start by power supply

The warning "Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter." is indicated in the precautions at the be... More Details >>

Difference between FR-AU01 and AU01A

The major changes from FR-AU01 to FR-AU01A include 1. Case material and 2. Lead wire terminal process method. The FR-AU01A has a backward compatibility with ... More Details >>

Communication operation with FR-E500

We have no sample program for RS485 communication. Since the communication method of the FR-SW0-SETUP uses a different protocol from 485 communication and st... More Details >>

Can I use a motor of which capacity is larger than the inverter capacity?

Even when the actual load (torque) is half of the motor capacity, the current output from the inverter to the motor is not reduced to the half. Therefore, it... More Details >>

Analog ammeter

We recommend the "YM206RI 1 mA" analog ammeter. More Details >>

Output specification between FM and SD

The output signal across FM and SD is pulse output. The output frequency and number of pulses of the output signal across FM and SD are proportional. However... More Details >>

Real sensorless vector control

No, Real sensorless vector control cannot be used in the FR-E700. More Details >>

AM terminal output

Set Pr.55 (Frequency monitoring reference) of the first inverter to 70 Hz. More Details >>

FR-SW1-SETUP

It is compatible with the -R type FR-S500. (It is not compatible with the FR-S500 without -R because it does not have the PU connector and thus cannot be con... More Details >>
