Title: Hoping for help with connecting PMDX-107 and Fuling DZB200 VFD
Post by: dhnaranjo on August 22, 2016, 03:55:33 PM

Hey, so first off let me say that I have actually no idea what I am doing.

I am trying to enable spindle speed control through Mach4 using a PMDX-107+PMDX-126 and I cannot for the life of me figure out how to wire it up.

The manual for the VFD, a Fuling DZB200B002.2L2DK, is available at http://www.manualslib.com/manual/828872/Fuling-Inverter-Dzb200-Series.html
A photo of the VFD with its ports exposed (oh my!) is here: http://i.imgur.com/YgBvrJP.jpg

I've looked at it and the PMDX-107 manual quite a bit and, honestly, this kind of stuff is not my territory. I'm an industrial designer by trade but I mess with electronics as a hobby so my boss figured I could handle it.

I super don't agree. I'd really appreciate any assistance.

Edited to add: My PMDX-107 is a Revision D1, if that is in any way significant.

I think I may have figured it out but I'd appreciate a sanity check.

Rev - S2 (Labelled as multifunction digital input, default function is reverse)
Fwd - S1 (Labelled as multifunction digital input, default function is forward)
COM - DCM
Aref - None
Aout - VI (Labelled as Analog voltage input, 0~10 (Max. output freq.) Input)
Agnd - ACM

My only hesitation is that I am unsure if DCM and ACM correspond to digital common and analog common respectively. I'm pretty sure, but I am not sure enough to risk setting my jobs robot on fire.

Thanks.

Those do indeed look like the correct connections.  DCM is the digital common and ACM is the analog common.
