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 >>

Motor heat generation at low-speed operation

When using the FR-A540-3.7K in Advanced magnetic flux vector control, operating the motor continuously under the 100% torque at up to 3 Hz does not cause a h... More Details >>

Using FR-A540 inverter on CC-Link

Answer to question 1 When the CC-Link option goes faulty, OPT (option error) occurs and the inverter's fault output is triggered. When communication is lost ... More Details >>

Torque characteristic at low speed

Torque is not guaranteed for slower than 0.5 Hz. Therefore, no data for this is published. Also, no torque is generated at 0 Hz. More Details >>

Remote operation of the inverter

The wiring length of the start signal (STF etc.) is 30 m or less. The circuit voltage of the control input signals (terminal STF etc.) is 24 VDC and the volt... More Details >>

Encoder feedback control wire

If the phase A and phase B are connected reversely, encoder feedback control is not performed. Instead, the inverter is operated in normal control (V/F contr... More Details >>

Amount of heat

The inverter (FR-A520-5.5K) itself generates approximately 310 W of heat. This is the amount generated under the inverter rated current 100% load. Since the ... More Details >>
