Lathe Jaguar VXS inverter - remote pendant

<< < (5/7) > >>

Looking in the linked manual, the Jaguar uses F36 and 37 as high and low frequency limits under speed control by panel or potentiometer etc., F30 as "start frequency", F03 as an absolute limit to prevent motor overspeed. I suspect "start frequency" is independent of the low limit but I could be wrong - I expect it may ramp from the start frequency to the low limit at start-up, then operate between that and max frequency - this may be worth experimenting with :)

Not wishing to hijack this thread, but my question is pertinent. I have a Mitsubishi inverter for which I have built a pendant, I have been able to configure the inverter so it responds to momentary push button inputs, so providing true no-volt fail safe.

I also have the same Jaguar inverter and would like to know if and how the above functionality can be programmed  Cheers

John Rudd:
Appletree,
Which Jag inverter do you have?
I have a generic schematic that I sent to Chris that will work....you may have to cross refer the numbers...unles I can find a way to up,oad pictures from my ipad.,, :Doh:

My Inverter is a Jaguar VXS 1.5kw if I remember correctly, its not so much the pendant it self but the programming and relevant connections to the inverter to give no-volt fail safe Regards

Appletree, I don't think the Jag can take pushbuttons (I'm pretty good at reading manuals  :coffee: ), only maintained (i.e. toggle / latching) switches - the "THR" input could be wired through a NVR though, requiring a poke of a button to reapply the closed connection although that wouldn't ensure the fwd or rev switch wasn't closed? You could put together a pair of interlocked small-signal relays to give pushbutton operation and NVR interlock, fairly cheap and easy BUT the Jag doesn't provide a suitable (i.e. sufficient current) supply, so you'd have the added complication of a transformer (and rectifier if using DC coil relays) and you'd need pushbuttons with dual pairs of contacts - both normally open and normally closed - to ensure you couldn't have forward and reverse energised at the same time (most VFDs will stop in this condition, the Jag's manual isn't clear on this...)

Myself, I have a lathe with a fwd/stop/rev lever on the carriage (with microswitches for fwd and rev) and added a "neutral" microswitch that has to close before I can apply power to the VFD through a contactor. No unexpected starts.
