So, what would I do differently?
It was a Tuesday in September 2022, and the email came through at 3:47 PM. I had two hours to re-quote a 14-drive ABB VFD order before our customer's purchasing deadline. Normally I'd send the spec to three suppliers and compare line by line. There was no time. I went with the first serious quote that came back, because the number was about 12% lower than our usual source.
That decision cost us roughly $9,200 in hidden costs and delays. I still wince when I think about it.
How I ended up in this mess
I've been handling ABB VFD and control component orders for eight years. I've personally made—and documented—11 significant mistakes, totaling roughly $30K in wasted budget. Now I maintain our team's checklist so nobody else has to learn the hard way.
The September 2022 order wasn't just drives. It was 14 ABB VFDs, 60 timers, a safety PLC, a stack of contactors and relays, plus some spare control components for a production expansion. The customer's BOM listed 'ABB VFD' for each drive slot, with a note that read 'OEM substitution accepted.' I read that as: genuine ABB drives supplied through an OEM channel, or maybe an ABB drive under a private label. In my head, all of those were basically the same thing.
They're not.
The quote that looked like a no-brainer
The reseller who quoted it called themselves a timer supplier and control components distributor. They also carried what they described as 'ABB-compatible OEM VFDs.' At the time, that phrase didn't set off any alarms. It sounded like a win: ABB-level quality for less money.
I should have stopped right there.
In the VFD world, OEM vs private label is not just a packaging difference. An OEM drive is made by a manufacturer and then built into a machine, usually sold under the machine builder's brand. A private-label drive is manufactured by one company and sold under another company's brand. Neither label automatically means 'ABB inside.'
The real question is: who actually made the drive, and who's responsible for it after it's installed?
I've learned to ask 'what's NOT included?' before I ask 'what's the price?' The vendor who lists all fees upfront—even if the total looks higher—usually costs less in the end.
I didn't ask that in September 2022. I asked for the price, got the lower number, and pushed the PO through. We had a deadline, and the quote looked clean.
The parts arrived. The problems didn't wait.
The order showed up in about three weeks—or rather, three weeks plus a week of back-and-forth on paperwork. The boxes had 'ABB VFD' printed on the outside, which made me feel better for about five minutes.
Then my customer's electrician sent me a photo of the drive nameplate.
Wait, no. That's not exactly right. He sent me a photo of the whole control panel, and I zoomed in on the drive. It wasn't an ABB drive. It was a private-label drive from a controller manufacturer I'd never heard of, sold through that reseller.
The surprise wasn't the name on the label. The real surprise was how much we'd been quietly relying on the ABB ecosystem: parameter files, manual layouts, training materials, support access. None of that came with these units.
The hidden costs stack up fast
Let me walk through what actually happened, because it wasn't one big disaster. It was a pile of small ones.
- The drives worked. Kind of. They spun a motor, but the programming structure was completely different from the ABB VFD parameter setup the customer's engineers knew.
- We had to track down ABB VFD training. The customer asked if we could get their team into a class. The private-label supplier didn't offer any. We ended up paying for an ABB VFD training slot with a third-party trainer—roughly $1,200 for two people, if I remember correctly.
- The timer order got messy. The reseller's timer supplier was fine, but the documentation was generic. It didn't match the relay and timer wiring diagrams we'd sent. The electrician had to redo a whole section.
- Support was a red flag. Oh, and the 'free phone support' the sales rep mentioned? That only covered basic questions. Fault code troubleshooting was a separate paid support tier.
- The warranty path was unclear. The reseller said to file claims with the controller manufacturer. The controller manufacturer's warranty form asked for a serial number format that didn't match the drives.
I want to say the initial savings were about $1,800, but don't quote me on that. It might have been less. Either way, the extras and delays added up to roughly $9,200—or rather, $9,200 plus a significant hit to our credibility.
The twist: the 'expensive' quote was the cheaper one
Looking back, I should have gone with the genuine ABB VFD quote. At the time, the reseller's number looked like the responsible choice because the line items appeared complete. They weren't.
Our usual supplier had included things the reseller's quote didn't show: parameter support, documentation matching, an ABB VFD training option for the customer's team, and a warranty path that didn't require a serial number scavenger hunt. That's why the number was higher.
In the end, we bought several of those services separately anyway. Bottom line: the private-label drives cost us more than the genuine ABB VFDs would have cost from the start.
What I do now on every ABB VFD order
That mistake changed my process. The checklist I keep now has caught 47 potential issues in the last 18 months. Here's the short version:
- Ask for the actual manufacturer name and country of origin on every drive. Not just the brand on the label.
- Confirm which ABB VFD training materials or classes are included, and who pays if the customer's team needs training.
- Get warranty claim steps in writing before the PO, including the serial number format.
- Check the timer supplier and controller manufacturer for every control component, and ask whether their documentation matches our wiring diagrams.
- Compare total cost, not quoted price. Include training, support, rework, shipping, and the price of a delay.
Per FTC guidelines (ftc.gov), advertising claims like 'OEM' or 'compatible' have to be truthful and not misleading. That's the rule on paper. In practice, it's on you to ask the right questions before you sign.
If you're comparing VFD OEM vs private label
I'm not saying private-label VFDs are always bad. There are solid controller manufacturers out there. But the label alone doesn't tell you enough. When someone calls a drive 'OEM' or 'private label,' ask:
- Who manufactured the drive?
- Who provides firmware updates and fault code support?
- Who handles warranty claims, and how long does that usually take?
- Does the drive use the same parameter structure as the brand I'm replacing?
- Is training available for the customer's maintenance team?
The most expensive question I ever asked was, 'Can you get me a lower price on ABB VFDs?' The better question would have been, 'What's not included in this price?'
So, what would I do differently?
If I could redo that decision, I'd invest the extra money upfront. But given what I knew then—under a tight deadline and with a quote that looked transparent—my choice made some sense. That's the tricky part. Bad decisions don't always look bad at the time.
Now I tell every new buyer on our team: price is what you pay at the beginning. Cost is what you pay by the end. On ABB VFD orders, make sure you know the full cost before you commit.
