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 >>

Stop-on-contact control

1. You can implement stop-on-contact.2. When implementing stop-on-contact, use the inverter to decelerate the motors to reduce the impact upon stop-on-contac... 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 >>

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 >>

Countermeasure against the fault occu...

When a CC-Link communication fault occurs, the option error (OP3) occurs on the inverter and the output is shut off, and the motor starts coasting. When usin... 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 >>

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 >>

Coasting

When the inverter output shutoff signal MRS is turned on, the output is shut off immediately without regard to setting of Pr.250. More Details >>

400 Hz output setting

Change Pr.18 (High speed maximum frequency) to 400 Hz.If you are using the analog command to set the frequency, calibrate the 400 Hz frequency with Pr.903. More Details >>
