KB controller help?

[stryder99]

I've been making some changes to my HF mini-lathe and one of the changes was to replace the FC250 controller bd.  I ended up going with a KBLC-19.  I can’t find a manual for that model so I was using the manual for the KBIC as a reference.  My motor is the 250 watt version so I used the #9840 horsepower resister (1/3 HP at 90VDC).  Wired it up and turned power on.  No smoke and spindle spins but fast.  What is a good/usable RPM to set max speed to?  I can figure out Max & Min but how should one go about adjusting IR and CL?.

KBIC manual here.....

There's a full setup procedure in there.....
I normally adjust the speed to correspond with the motor voltage....if your motor is the 90v one then adjust the max speed for 90v at the motor terminals....

Hi
Good choice using a KB Electronic Controller.
As john has given you the URL for the control the full setup instruction are all there.
The motor speed is 6000 RPM.
 The CL (Current Limiter) will give overload protection for the motor when set correctly to the manual.
 The IR Comp will keep the motor speed constant for varying loads.
