Anyone know how to wire an ac motor to a fuji ps r751h controller? I can't find a manual anywhere. Here's how the controller terminals are marked,
1 2 U V X T1 T2 A1
I think 1,2 is ac in, and T1,T2 is motor in, but not sure, and no clue on the rest, or even where ground is. I'd like to put it on an ac wood lathe, and use it for finishing.
Thanks, scott

Just guessing but...

It is using standard alpha numeric references for the basics. 1 and 2 are your AC line voltage input. T1 and T2 is for the motor. A1 is also used for motors with a separate armature connection. These motors should have connection diagrams that identify armature and field connections. U, V and X are used to represent different things but are usually an optional input or output. As there are three they would most likely be for a remote potentiometer to control the speed, a speed feedback from an optional sensor, or for connecting multiple controllers together so a single knob would control multiple motors. Circuit boards designed for similar purposes usually do not provide a user ground connection on the board. The available ground will either be a chassis mounted threaded post or a tapped hole with a single wire connected from the circuit board. The wire should either have solid green insulation or green with a yellow stripe depending on whether the ground is common to the input and output circuits or not. If it is green with the yellow stripe you must ground the motors chassis to this same point to ensure safe and proper operation. As long as your lathes motor does not require a start or run capacitor the controller should work great.
