Do i need to use this output from my DC motor speed control board? Answered

With the goal of using the DC treadmill style motor that i have in a project (or two), i have baught a SCR speed control board.
The circuitry of the control board has outputs for the armature and field coil (labeled "excitation"). But the motor that i have is a permanent magnet type (2 wires going in / out  - red and black - nice and simple). So i don't need the 'excitation' output. My question is whether the control board needs this to be used? Am i going to fry my brand new controller if i only draw current through the armature output? I could, for instance, put a resistive load accross this output to make it use just less than the output it's rated for.

Here's more info on the parts in question:
The speed controller is like this:  http://www.ebay.com/itm/DC-0-220V-Continuous-Adjustable-Dc-Motor-Speed-Regulator-Control-Board-1000W-/251600102759?pt=LH_DefaultDomain_0&hash=item3a9488e567

The motor is either of the models on this page (i actually have one of each): http://www.ectrade.com/Auction/FreeSample/1931851586/Electric_treadmill_motor_DC-specific.html

Thanks in advance.

Theoretically, if there is no field current, the controller should shut down. See what happens, it might work on no field, it won't wreck the control if its not present.

Wow I sure could use a DC treadmill style motor this next week.
