Automation Repair Services in Indianapolis, IN

Somewhere in most central Indiana plants there is a machine nobody can buy parts for. It was built to order by a company since sold, merged, or closed. The drawings went with it, the spare it shipped with was consumed years ago, and the only surviving example of that controller is bolted to the frame. When it quits, there is no catalog number to order.

IVS Incorporated exists for that situation. We repair automation hardware down to the component, on units nobody supports any more, so an orphaned machine goes back to work instead of onto a capital request.

The Manufacturing Mix Across Central Indiana

Indianapolis carries an unusually broad industrial base for its size. Pharmaceutical and life sciences manufacturing anchors the region, alongside a motorsport and precision engineering cluster serving racing and aerospace alike. Around them sit automotive component plants, electrical equipment makers, plastics processors, food production, and distribution.

Much of that work runs on purpose-built machinery rather than catalog equipment — a packaging line for one product family, a test stand for one component, a transfer machine built for a single plant — and such machines age with no upgrade path.

When the Machine Builder Is Gone

Custom and single-source machinery ties a plant's output to companies that may no longer exist. The integrator who wrote the program has retired. The OEM's number now reaches a different business. There is no manual, no schematics, no parameter backup, no support agreement. Maintenance is left holding a machine that ran beautifully for twenty years and a failed drive with a nameplate nobody recognizes.

Repairing that unit is then the only route that keeps the machine intact. Replacement means re-engineering the control system around whatever hardware fits, re-integrating feedback devices nobody documented, and re-proving a machine whose acceptance criteria are lost — a project, and projects take quarters.

So our work on orphaned hardware starts at the board. We trace circuits on units with no service documentation, identify failed parts by measurement rather than reference, substitute components out of production for decades, and reverse-engineer whatever we must to test the repair honestly. Keeping the original hardware in place preserves the machine's behavior and feedback loop.

Breakdowns That Halt Indianapolis Production Floors

Obsolete controllers with no replacement path. Discontinued PLC processors and I/O modules fail with no equivalent available, and the logic will not move to a modern platform without significant rework.
Servo drives and amplifiers from defunct builders. Motion hardware from OEMs that left the market a generation ago still runs precision equipment here, and a failed output stage has nothing to swap in.
Feedback devices with no match. Resolvers, encoders, and tachometers on legacy servo and spindle motors are often proprietary to one machine, so a rebuild must preserve and realign the original.
Interfaces that outlived their displays. Custom panels lose backlights and touch response, and the display module they were built around has not been made in years.

Our Repair Path, Step by Step

Ship it to us. Send the failed hardware to Plymouth, Michigan and tell us what the machine was doing when it stopped; a rough account helps when nothing is documented.
Free evaluation. Our technicians establish the actual cause at no charge, whether or not you proceed.
Written quote. We put the price and our recommendation in writing first, so the cost never arrives as a surprise.
Repair with full in-house testing. Approved repairs are completed on our bench and proven by functional testing, never signed off on inspection alone.
Returned with a guarantee. Your unit comes back protected by a 12-month in-service guarantee on parts and workmanship.

Hardware Categories in Our Shop

Programmable controllers — processors, I/O cards, communication modules, and chassis, including long-obsolete platforms.
Drives, inverters, and amplifiers — servo drives, spindle drives, AC and DC drives, and their power supplies.
Motors, servos, and gearboxes — rebuilt with new bearings and seals, balanced rotors, machine work on shafts, bearing fits, endbells and keyways, and aligned feedback.
Operator interfaces and displays — panel repair, screen and backlight work, and controller communication.

Two guides cover ground that comes up constantly on undocumented machines: PLC troubleshooting and maintenance, on isolating a fault in a live rack, plus how to test a servo motor, on the measurements that identify a failing axis.

Reasons Indiana Plants Send Work Here

Component-level work on unsupported hardware. We repair units with no documentation, no spares, and no manufacturer left to call.
Three decades of accumulated familiarity. Over thirty years in this work means we have usually met the platform before, even when it died in the nineties.
Testing that proves function, not just continuity. Repaired units are exercised on our test equipment before they are packed.
Clear terms up front. A free evaluation, a written quote before work starts, and a 12-month in-service guarantee behind the finished repair.
