Can I connect a brake resistor?

You cannot connect a brake resistor to the FR-U100 series inverter. (Use the FR-A024 series if you use the brake frequently.) More Details >>

Can I input speed setting externally with the box type?

No. Use the potentiometer on the box to set the speed. If you want to input analog values externally to set the speed, use the unit (module) type. More Details >>
