I bought an early HLV some months ago. It is a 3-phase 240v machine and I have rewired it to operate the main drive and coolant pump using VFDs to convert 240 single phase to the three phase needed for the motors. I've removed to old control system and wired to get spindle forward, reverse, high and low speed operating and I'm now on to getting the carriage feed to work properly.
There was no wiring diagram with the machine and my tracing of the old control system had the carriage feed controller hooked up to a 120v ac transformer. When I apply 120v ac line voltage to the controller, nothing happens.
I could use a wiring diagram and some help troubleshooting the controller and drive motor. The controller panel has on/off, high/low, and left/right switches and a status light around the large speed control knob. The carriage feed motor is 90V dc 1/15hp.
Assistance would be sincerely appreciated.
