Does anyone have a manual for the KTK drives that came in the bridgeport machining centers. Mine came with a CT drive and I am having it replaced with a new drive. My prints show the wiring for the KTK drive. I need to know what wire input numbers 4,5 and 12 are for. They are all tied to wire number 27 but i would like to find out what the drive calls out for these positions.

Thanks,
Craig

I have another question for you. I have call Bpt but I cant seem to get any support from them at all.

The tech working on the machine has installed a new CT drive. The spindle is rated at 6000 rpm. When the control applies 72% the spindle is only turing around 1500 rpm or so. Do you know the details of the motor for the prameters in the drive. Also the tech is asking questions about number of pulses ect...that I cant answer. Do you know what he is asking for?


Thanks,
Craig

The details of the motor should be stamped into a plate on the side though you may have to physically remove the motor from the machine to be able to see it.

On a semi-related note. Is Contraves & KTK the same thing or are they two different companies ?

The first machines came with contraves spindle drives. Later machines were built with the KTK. Not interchangable.
