Frequency meter

First, check if Pr.55 (Frequency monitor reference) that is the reference for the FM output is set correctly.Next, operate the inverter (without connecting a... More Details >>

Output frequency monitor value

When running the inverter after auto tuning, the frequency setting value is increased by the amount of the motor slippage, resulting in a higher monitor valu... More Details >>

Advanced magnetic flux vector control

Check the parameters necessary for tuning again.Check if Pr.9 (Electronic thermal O/L relay) and Pr.81 (Number of motor poles) are set correctly. More Details >>

Auto tuning

Set it to "13" (Constant-torque).　　 More Details >>

Frequency, monitor setting

Set Pr.52 (PU/DU main display data selection) to "5".Set the monitor as the third monitor, frequency -> current -> setting frequency. More Details >>

FR-Configurator

No. You cannot connect it to multiple inverters.You can only connect a single personal computer to a single inverter via USB. More Details >>

What is the replacement of the FR-BOL?

We do not offer a replacement product for the FR-BOL (noise reduction reactor). Since the FR-A100E is a low-noise type inverter, the motor noise is suppresse... More Details >>

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 >>

Imbalanced input and output side power supplies

1. In general, the input power of the inverter is always larger than the output power because the inverter loss is added to the motor loss. 2. In both of cas... More Details >>

Inverter input current

Since the input current has a distorted waveform and the waveform ratio is low, the total inverter input power factor is very poor depending on the power sup... More Details >>
