Scott 35 said some time ago that he had some info on the use of resistors to control the speed of a overhead crane motor. If you do could you post them or e-mail them to me? I have 2 weeks vacation and would have the time to study them before i go back to work. I would really like to have a better answer for the boss than, "it appears to be ok electrically, don't know why it's not working?!" Thanks, spkjpr.
