Suggestion for replacement of inverters
We do not offer book type inverters. Therefore, the S500 is recommended to replace the Z123 because of its compact design. If regenerative driving matters, c... More Details >>
Influence on external measurement device
It is considered that malfunction of the measurement device is due to noise. Check the noise propagation route since the countermeasure depends on it. Some c... More Details >>

As you mention, when the inverter is operated only with STF without inputting the speed command signal, the minimum frequency must be set to 10 Hz.However, a... More Details >>
Inverter's heat generation quantity
The heat generation quantity while the inverter is outputting the rated current is as follows:1. FR-A520-3.7K: 230 W2. FR-A520-7.5K: 420WThe heat generation ... More Details >>
Switching from star-delta operation
It is probable that the torque is insufficient because the load characteristics and inverter output characteristics do not match and the output current value... More Details >>
Use the FR-HC to suppress harmonics. It also supports power supply regenerative driving.The FR-CV and FR-RC are both power supply regeneration units.The diff... More Details >>
Many geared motors cannot continuously operate at low speed (for example, slower than 6 Hz) due to grease viscosity.If the motor you are using is of this typ... More Details >>
