Brake sequence function

Since the brake sequence function requires Advanced magnetic flux vector control and advanced flux control is applied to 0.4 kW or higher motors, you cannot ... More Details >>

Vector control of the inverter

The speed fluctuation ratio under Advanced magnetic flux vector control of the FR-A500 is as follows. Without encoder: ±1% With encoder (with A5AP): ±0. 02 %... 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 >>

Auxiliary input power supply

If you connect two frequency setting potentiometers to the terminals 5 and 10, the permissible current of 10 mA is exceeded, and you need to install 2 KΩ res... More Details >>

Faults history upon power failure

When an instantaneous power failure of 100 msec or longer occurs, the inverter is reset* and it is not recognized as a fault. Since it is not recognized as a... More Details >>
