When I first started handling our company's ABB VFD orders around 2021, I thought it was pretty straightforward. Look up the model (ACS580, ACS880), check the price, place the order. It took about three months-and one expensive mistake-for me to realize that getting an ABB VFD isn't a one-size-fits-all thing. It depends entirely on what you're doing with it, how much support you need, and whether you're the engineering team or the person signing the PO.
So let me break this down into three scenarios I've seen play out. Figure out which one you're in, and you'll save yourself the headache-and maybe a few hundred dollars.
Scenario A: You're Engineering & Need a Specific Model (ACS880, ACS580)
If you're specifying an ABB drive for a new machine or a replacement, you probably know exactly what you need. The ACS880 is their high-performance drive, often used for cranes, hoists, and demanding process control. The ACS580 is the general-purpose workhorse-pumps, fans, conveyors. If you're in this camp, your main concern is availability and price.
What I've found: For specific models, particularly the ACS880 with custom I/O or fieldbus options, the price list is not really a list you can just look up. The ABB VFD price list PDF you find online? It's usually a list price, and nobody pays list. A 10hp ACS580 might list for $2,800, but a distributor will sell it for $2,100 or less. The difference can be 20-30% off list for standard drives.
I still kick myself for not asking for the net price on our first big order. We paid list on a pair of ACS880s. If I'd called a second distributor, I would have saved about $1,200. The trick: call three distributors, ask for their best price on the specific part number, and give them a purchase order number on the spot. That's how you get the real ABB VFD price.
One more thing: the wiring diagram PDF. It's usually available on ABB's site, but for older drives like the ACS800, you might need to call support. Keep the serial number handy.
Scenario B: You're Not Sure What You Need & Just Want It to Work
This is the scenario I see most often with small manufacturers or facility maintenance. You have a pump motor that's been running on a failed drive, and the production manager is yelling. You need a replacement, but you don't know your ACS800 from your ACH580. This is where it gets tricky.
My advice, based on experience: Don't just buy the cheapest drive from a generic supplier. Why? Because when you get an ABB VFD, you're paying for the support ecosystem. The ABB technical support phone number is actually useful. I've called them twice. Once for an earth fault alarm on an ACS580 (bad motor cable, not the drive), and once for an alarm 2021 (Start Enable 1 missing) on an ACS800.
Here's what most people don't realize: the alarm 2021 on an ACS800 is almost always a wiring issue-usually the emergency stop circuit not being closed. The drive is waiting for a safe start signal. I wasted two hours on the phone before I figured that out. The second time, I knew to check the wiring first.
If you're in this scenario, look for a distributor that offers technical support and a return policy. Some online sellers will ship you an ABB VFD, but if you plug it in and get an alarm, you're stuck. I recommend buying from a known ABB channel partner. Yes, it might be 5-10% more expensive. But the first time they help you troubleshoot an alarm over the phone, you'll get that back in saved downtime.
Scenario C: You're a Small Shop or DIY & Need a Budget Option
This is the most controversial scenario, and I say this carefully. I've seen small shops buy a used or refurbished ABB ACS800 on eBay for a fraction of the cost of a new one. And sometimes it works. But I've also seen them get a drive that throws an earth fault after a week, and the seller is gone.
Honest recommendation: If your application is critical (a pump that runs your whole line), don't go used. Get a new ACS580. But if you're building a test bench or running a non-critical fan, a used ACS800 from a trusted supplier (one with a 30-day warranty) can work. Look for a drive that has been tested and comes with a manual.
The one thing I'd avoid: buying a drive without knowing how to set the parameters. The ABB VFD parameters are what make the drive work for your motor. Without the right settings, even a new drive will have issues. Spend 30 minutes reading the manual.
How to Know Which Scenario You're In
Here's a quick self-check:
- You're Scenario A if: You have a specific part number, you know your power requirements (e.g., 10hp, 200kw), and you're talking to a distributor.
- You're Scenario B if: You have a failed drive, you need it replaced fast, and you want someone to help you set it up. Prioritize support over price.
- You're Scenario C if: Your budget is tight, you can accept some risk, and you have time to tinker. Be prepared to troubleshoot.
There's no single right answer. The best ABB VFD for you is the one that matches your situation. I've learned that the hard way. Hopefully, this saves you from making the same mistakes I did.
