What we see from Charlotte
Charlotte is built on energy and turbine equipment manufacturing, automotive and motorsport engineering, textiles and metal fabrication. That mix decides which controls end up on our bench: energy equipment, automotive, textiles and metal fabrication all depend on operator terminals, drives and power supplies that reach end of life long before the machines they run.
With roughly 3 business days of ground transit each way and 3–5 business days on the bench, most Charlotte customers are back in production well inside the lead time quoted on a replacement unit. When a line is down, overnight shipping plus rush service compresses that further.
We are not a local depot in Charlotte and do not pretend to be — this is a mail-in service run from a single bench lab in Arlington, Texas. What that buys you is a technician who repairs these units every day rather than one who sees one occasionally, and the same 24-month warranty wherever you ship from.

VFD Repair (ABB, Yaskawa, Danfoss & More) in Charlotte — common questions
My machine in North Carolina is down right now — what's the fastest path?
Overnight the unit to our lab with rush or emergency service selected and it goes to the front of the bench the day it arrives. From North Carolina, overnight shipping plus a 1–2 day rush bench typically beats any replacement lead time by weeks.
Can North Carolina plants set up a commercial account?
Yes — maintenance teams and integrators in North Carolina can open a commercial account for PO acceptance, priority queue, and repair history by serial. It's the same published pricing, with less friction on every subsequent repair.
Is my program safe shipping it out of state?
Yes. Applications and parameters live in the unit's protected memory, which our physical repairs never touch — and units are logged, photographed, and tracked by RMA from arrival to return shipment.
