Compatibility with Y-△ motor and others

1. You can connect them using △ connection. 2. No problem with connecting four Y-△ motors. (Connect all four motors using △ connection.) (Note that the inver... More Details >>

Connection with pole change motor

Since the inverter allows for changing speed, fix the number of poles when using the pole change motor. It is recommended to fix the number of poles to four ... 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 >>

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 >>

Current monitor display

The current monitor displays the average value of the three-phase current. The three-phase voltage is not incorporated for the voltage monitor. The output vo... More Details >>

Vector control of the inverter
