Help changing PD values in a Huanyang

[BanduraMaker]

Help please, I am completely at my whit's end with this thing:

I just received a 2kW Huanyang VFD to control my spindle. I've found plenty of pages on what settings should be used but for the life of me, I can't figure out how to change the settings of anything on this damn thing.

The keypad doesn't match the one in the manual (which seems pretty common) and the directions in the manual don't match the keys one page earlier.

When powered up, the display flashes 52.xx or something like that and I can change stuff to the right of the decimal with the up and down arrow keys.

By pressing PGM, I get the display to change to PD000 and the up arrow increments the value but the down arrow doesn't decrement it. Pressing PGM again takes me back to the flashing frequency display.

None of the other buttons seem to do anything.

Can anyone help???

Have you sorted this yet? I noticed this post is 6months old but there is no replies. I may be able to help. Martin

I solved it by buying a Hitachi VFD which is performing flawlessly. I still have the Chinese one but it's just collecting dust. I think that some of the keys on the keypad are broken.

Busted out of frustration?

Something like that. Oh, and the 9mm holes through the device might be causing some issues too

Hi MCraggs
I just purchased a 3kW Huanyang VFD to control my spindle. I'm having the same exacted problem as BanduraMaker. Have you seen this problem before and if so is it something we can fix or do we toss it in the garbage and purchase a new higher quality VFD?
