Encoder cable length restriction

If the cable length is longer than 100 m, speed may not be read correctly due to voltage drop and waveform deformation of the encoder signal. Therefore, use ... More Details >>

Advanced magnetic flux vector control

When using the geared motor GM-S(B), set Pr.71 to "13" and also set Pr.9, Pr.80, and Pr.81.Perform auto tuning as required. Perform auto tuning as required. ... More Details >>

Auto tuning

Check if any device is connected to the inverter's external terminal.In particular, check if MRS and SD are short-circuited.If they are short-circuited, open... More Details >>

Auto tuning

If you have already set other parameters necessary for tuning (Pr.9, Pr.71, Pr.80, Pr.81, Pr.83, and Pr.84), press the MODE button to return to the frequency... More Details >>

Frequency setting

Since Advanced magnetic flux vector control is chosen, the inverter calculates how much the motor rotation slips from the flowing current and adds the slip a... More Details >>

FR-E520 7.5 kW model

Inverter current characteristics

In general, relationship between T (torque), K (constant), V (voltage), I (current), and F (frequency) is expressed as "T = K × (V/F) × I". Since (V/F) is co... More Details >>
