Parametrics VFD

[JRaef]

I used to work for ABB shortly after the Parametrics era and sold the Parajust drives under the ABB label for a while. Parametrics was bought out by Asea (Sweden) in 1986, then Asea merged with Brown Boveri (Switzerland) in 1987 to form ABB. ABB US continued owning and operating the old Parametrics plant in Conneticut until 1990 when they began importing the ABB drives from Finland (what is now the ACS Series). The Parametrics plant was shuttered and although most employees were offered jobs at the ABB plant in New Berlin Wisconsin, 99% did not make the move. Some started their own company, AC Tech, everyone else dispersed into the industry.

The FHP however was never made by Parametrics, it was brand-labeled from Yaskawa, who used the same FHP name for their version (KB drives also brand labeled it, that's why someone thought there was a KB connection). When ABB got rid of the Parametrics name (widely despised for quality problems), they stopped the agreement with Yaskawa too. You could still buy them from Yaskawa for a while afterwards, but they were the last of the analog drives and although cheap, they were very low functioning compared to what else was out there. Yaskawa dropped them in (I think) 1992. By then I had worked at Motortronics and we were brand-labeling them too, but Yaskawa cut us off because they wanted out of their contracts so they could close that production line too.

So the likelihood of you finding someone to help with what was, even at the time a <$100 drive, is pretty close to zero. I long ago tossed out any manuals I had. Besides, drives that old are not worth the cost to fix them, there are a lot of parts that are no longer available and the capacitors are likely to be on the verge of failure if they haven't already. If it were me, I would replace it now with a new drive and not risk collateral damage when it does fail in the very near future.
