Robot, PLC and HMI repair

Board-level electronics through to wrists and gear units. Every job is diagnosed before it is quoted, validated on our own test rigs before it ships, and carries a six-month warranty in writing.

Scope

What comes across the bench

Board-level electronics through to mechanical assemblies, for robots, controllers and the automation hardware around them.

HMI & operator panels

ANY MAKE

Membrane and keypad replacement, touch-screen and digitiser replacement, LCD and backlight, power and logic boards, corroded connectors, cracked frames and bezels.

PLC racks & modules

SIEMENS · ALLEN-BRADLEY · MITSUBISHI

CPU modules, digital and analog I/O cards, communication and network cards, power supplies, backplanes and rack wiring, battery and memory-backup faults.

Industrial PCs

ANY MAKE

BGA chip-level rework, power board repair, capacitor replacement, thermal faults, and full disk-image backup so the machine's configuration survives the repair.

Robot controllers & drives

KUKA · FANUC · ABB · YASKAWA

Controller cabinet faults, servo drive and amplifier repair, safety and I/O boards, teach pendant repair including cable, enabling switch and touch panel.

Servo motors & encoders

ALL BRANDS

Winding and bearing faults, brake units, encoder and pulse-coder replacement, shaft and keyway repair, re-testing under load before return.

Mechanical assemblies

ALL BRANDS

Inline wrists, counterbalance systems, gear units and reducers, backlash correction, seal and lubrication service, and dresspack rebuilds.

How a repair runs

Diagnose, quote, repair, prove it works

The step most repair shops skip is the last one. A unit that has not been run under load has not been repaired — it has been worked on.

Diagnosis before price

Every unit is diagnosed before anything is quoted, so the price you get is for the fault that actually exists rather than an estimate hedged against the worst case. If a unit is not worth repairing, that is the answer you get, along with what a tested replacement costs.

Validation on our own rigs

Repaired units are run on test rigs built for the platform before they are packed. This is what catches the second fault that was masked by the first — the one that otherwise surfaces two weeks after the unit is back on your line.

Line down?

Emergency fault-line support for unplanned downtime, with same-day diagnosis and priority component dispatch for AMC subscribers.

Repair or replace, honestly

We supply spare parts as well as repairing them, so we have no reason to push you either way. A drive or pendant that can be repaired for a fraction of replacement cost gets repaired, and we say so even though the parts sale is the larger invoice.

Sending a unit in

What to send with it

Five minutes of preparation usually takes a day or more off the turnaround, because it saves us going back to you before diagnosis can start.

  • The part number and revision from the component label, left visible.
  • The machine it came from — robot or PLC model, and the controller generation.
  • The fault as it appears: error code, what the machine was doing, whether it is intermittent.
  • Any previous repair history on that unit, including work done by others.
  • Anti-static packing for boards and pendants, inside a rigid outer carton.
  • A note inside the box with your name, company and phone number.

Test rigs

The warranty is built on the rig

We keep working controllers and platform-specific rigs in the workshop so a repaired board, drive, pendant or motor can be run in the environment it will go back into, not just continuity-checked on a bench.

The same rigs are what let us sell tested used parts with a one-year warranty. A part is either proven under power or it is a guess, and we do not ship guesses.

Send us the fault. We'll diagnose before we quote.

Brand, model, error code and what the machine was doing. Most quotes come back within one business day, and nothing gets repaired before you approve the price.

FAQ

Questions we get asked most

What do you repair?

HMI screens and operator panels, PLC CPUs and I/O cards, industrial PCs, robot controller boards, servo drives and amplifiers, teach pendants, servo motors and encoders, and mechanical assemblies including inline wrists, counterbalance systems, gear units and dresspacks.

Which brands do you service?

For robots: KUKA, FANUC, ABB and Yaskawa. For PLCs, HMIs and industrial PCs: Siemens, Allen-Bradley, Omron, Mitsubishi, GE Fanuc, Hitachi, Telemecanique, Schneider, Modicon and VIPA.

What warranty do you give on a repair?

Six months from the date of repair, on every job. That warranty is only possible because each unit is run on our own test rigs before it goes back, which is also what catches the secondary faults that would otherwise bring the unit straight back to us.

Do I get a price before the work starts?

Yes. We diagnose first, then quote a binding price. Nothing is repaired before you have accepted it, and if we find during diagnosis that the unit is not economically repairable we tell you that instead of quoting around it.

How long does a repair take?

It depends on the fault and on parts availability, and we give you an expected turnaround with the quote rather than after you have committed. Dresspack repairs are typically diagnosed, quoted and returned inside a week. Line-down jobs are triaged ahead of scheduled work, and AMC subscribers hold priority.

What if the unit cannot be repaired?

We tell you what it would cost to replace it with a tested refurbished or new unit, and you decide. We hold spare parts for the same platforms we repair, so in most cases the alternative is available from the same conversation.

How should I pack and send a unit for repair?

Send the component with its part number visible, a short note of the fault and the machine it came from, and your contact details inside the box. Anti-static packing for boards and pendants, and a rigid outer carton. Message or call us before dispatch so the bench is expecting it.

Can you repair on site instead?

For faults that are diagnosed on the machine — controller health, wiring, dresspack and mechanical issues — yes, and that is how AMC and emergency call-outs usually run. Board-level and motor work comes back to the workshop, because the test rigs are what make the warranty meaningful.
