Minit lathe - can you help ID my wiring?!

Firstly you only need to use terminals marked F if you have a shunt wound motor, I am assuming that you only have two wires coming out of yours if so you just use the A marked terminals.

The sense resistor is used in some drives as part of a feedback circuit to limit the amount of current the motor can draw, and help prevent your motor from burning out, it can also help out with low speed torque issues, this subject can get quite complex so we'll leave it here!

Anyway this rs part number should help you: 199-6356 it is for a 0.03 ohm 6W resistor which is just about right for you. As peter correctly says your dissipation will only be about 0.3 - 0.4 w.

You posted while I was typing, glad you got it going Rob.
