Hi

I've swapped an IMO Jaguar CUB5A-1 from my old Viceroy lathe to this one, I bought the kit originally and really don't remember setting it up, in fact the company I bought it off may have supplied it set up with the pendant already fitted.

My question is how do I power the 3 phase board that works the other stuff on the lathe like the tacho, pump, E stop & safety switches etc.

Can it be wired somehow to the inverter or would I have to get another? I've taken some photos and will try to upload them

thanks in advance

Allan

Your e-stop and safety switches can be wired together in series and used to make the RUN enable connection on the VFD.

The suds pump will almost certainly be happy to run on single phase with just a capacitor on the spare leg.

The tacho is probably single phase already, but only investigation will find that out.

Thanks Pete, I'll take some more photos tomorrow as for some reason I didn't take one of the other electrical relay type components

thanks

Can anyone tell me if the left hand part is likely to be a transformer 400v to 230v? I think it is but no labelling.

If it is I can sort the wiring easily but just worried in case it a voltage drop lower that 230v

thanks

It was quite common to power the control gear off 240 volts using only one phase of the incoming three phase. Often the voltage was further reduced to a safer 110 V using a transformer.

I suspect this is how your control side is arranged so the transformer is a 240 V input to 110 volt output (nominal).

There should be a coil voltage marked on the lower part of the contactor. Bound to be underneath or round the back of course and may no longer be legible. If you have a source of coils the can easily be swopped on that breed of contactor.

When you finally wire things in it may be wise to connect the machine light so its always on when the machine is powered up and ready to run. A big warning light really. Especially if you use the little buttons on the VFD to control things as it only takes a light touch to get things moving. Having come "THAT" close to starting something up in a potentially lethally dangerous state I always like the Go button to be distinctly positive.
