I bought a used 22x22 moving table Multicam it came out of Bell Helicopter where they used it in there lab. It's approximately 8 years old and very clean.
I have experience using a Wincnc controller that uses a pc to run files and execute commands using either the keyboard or the buttons on the interface. The controller on the Multicam does not use a pc and any manual commands are entered using a pendant,(which is broken).
The controller nameplate calls for 460v/15A. The spindle is a Perske 2hp at 380V, there is a transformer in the controller cabinet to convert the 460v to 380v before the power goes to the invertor. The controller has three boards, (drivers or amps) one for each axis. Various other boards, breakers, fuses, capacitors, resistors, relays, etc.. Harware includes a tool touch off pad, proximity home limit swithes, and coolant lines. It is capable of tool offsets, spindle speed and on off. All the wiring is clearly numbered and everything is neat and orderly, it looks like nothing has been altered.
When under power everything seems to power up but the axis motors won't run and the spindle will not run.
The pendant has a mechanical e stop and a mechanical two position switch, these both work but none of the other switches do and the l.e.d. read out does not light up. The switches that do not work are all touch swithes that make contact on a computer style board that is full of solder joints and has two 3/4" square computer chips. The pendant looks like a small computerer itself.
My questions are:
1) Can this be practically converted to single phase 230V. I am willing to replace the invertor.
2) If single phase is not practical is 230v 3 phase practical.
3) How to reconfigure the wiring in the Perske. It is dual voltage 380 or 230 three phase.
4) Repair the pendant or replace it.
5) How to load files and run files, (there is an unused 9 pin plug on the side of the contoller cabinet, is this for a pc or some type of memory device)?
Anybody have any advice or know of a place to contact that does this type of work? Advice is preferable, this looks like a fun project.
Thanks,
Joe
