Durability in multi-speed setting

1. You can set the minimum time by setting the acceleration/deceleration time and acceleration/deceleration reference frequency. 2. No problem with the termi... More Details >>

Installing magnetic contactor on input side of inverter

Basically, there is no difference between the A200 and A500. For safer use, from the A500, it is recommended to completely shut off the power supply by turni... More Details >>

Motor retention at 0 Hz

The inverter does not have a function to limit the current at 0 Hz.Although it has the DC injection brake, it is intended to improve the braking capability b... 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 >>

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 >>

Inverter communication

Check if the communication setting parameters (Pr.117 to Pr.124) are set to the same values between the inverter and personal computer.Note that communicatio... More Details >>

Operation by single-phase power supply

Similarly to the FR-A220, single-phase power supply operation is possible by reducing the inverter's output current.Ensure that the output current is smaller... More Details >>

Two-rank up maximum short-time torque

It is not possible to generate torque larger than the maximum possible torque of the motor by increasing the inverter's capacity.Even when the inverter is up... 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 >>
