Gday Everyone.
I have one of these Isacon HY series VFD's (Like a lot of people I bought it thinking it was a Huan Yang. Luckily for me I only paid $125 AUD for the VFD plus a 1.5 Kw 3 ph motor - both unused).
So, I have mounted the new motor to my lathe and wired the VFD. It runs the motor quite well from the panel (which doesn't not have a potentiometer on it. ) but its got me beat as to getting it to run with an external pot for frequency (speed) control.
There are lots of copies of the user manual on the net but I've yet to find anything about running one from an external pot.
The diagram in the book shows a "1-5k" pot. So I have a 5k pot wired in as per the diagram. I have changed the settings (Pno3 -"Source of runtime frequency" to 1 for potentiometer but it doesn't work.
So has anyone else with one of these, wired up and gotten working, an external pot?
Any advice would be greatly appreciated.
Atm I don't have any scans of the manual with me that I can post up.
meanwhile if I have any success I'll post up the results here
thanks in advance
Peter
