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?.
