Power stage rebuild
IGBT modules, gate drivers, and DC bus capacitors replaced on Kinetix, SINAMICS, Sigma, and Fanuc amplifier hardware.
Independent third-party component-level repair of servo drives on packaging and bottling equipment: filling machines, labeling lines, cartoning, palletizers, and form-fill-seal hardware. Allen-Bradley Kinetix, Siemens SINAMICS, Fanuc, and Yaskawa drives.

Where These Drives Sit
Below are the four common packaging-line contexts where servo drives end up at the bench.
Volumetric filler, dosing pump, and capping-head servo drives across food, beverage, and pharma lines.
Web-fed labeler servo drives, glue applicator, and cartoning-machine flap and erection servos.
Servo drives on case packers, robotic palletizers, and end-of-line wrap and stretch hardware.
VFFS / HFFS film advance, seal-jaw closing, and cutting-knife servo drives across continuous-motion lines.
What NC Servo Does
Each unit is opened, inspected, and rebuilt at the component level. Failed parts come from inventory or off donor units. Bench verification before ship.
IGBT modules, gate drivers, and DC bus capacitors replaced on Kinetix, SINAMICS, Sigma, and Fanuc amplifier hardware.
Component-level board repair, firmware checks, and communication-module verification on packaging-grade drives.
Cooling-fan replacement, power-supply rebuild, and thermal-path checks on cabinet-mounted hardware.
Electronic test setup with dummy load and feedback emulation. Performance check before ship.
19,000+ unit in-house pool. Aftermarket parts and donor units for legacy packaging-line hardware.
Hardware repair only. PLC programming, machine commissioning, and line-tuning stay with the customer or integrator.

Common Faults
Packaging-line servo drives run continuous duty in tight cabinet environments. Failures fall into four categories.
| Power stage | Failed IGBT modules, blown DC bus capacitors, and gate-driver damage. Often follows a power surge or cooling failure on the cabinet. |
|---|---|
| Cooling & thermal | Cooling-fan failure, heatsink contamination, and thermal-stress damage on the power module. |
| Control electronics | Communication-module failure, encoder-interface damage, and capacitor aging on the control board. |
| Cabling and connectors | Damaged feedback cables, encoder connector wear, and corrosion on encoder pins after cleaning-cycle exposure. |
Workflow
Same four-step path through the shop whether the drive came off a Krones bottling line or a Bosch packaging cell.
Call or email with the part number, equipment context, and a photo of the nameplate if it helps.
Tech inspects the drive, runs it on the test bench, and confirms what failed.
We call back with the cost and a rough turnaround. Nothing is started without your sign-off.
Failed components replaced from inventory or off donors, drive verified on the bench, and shipped back.
FAQ
Application-specific questions. For brand-specific FAQs, see the dedicated brand page above.
Servo drives and amplifiers from Allen-Bradley (Kinetix), Siemens (SINAMICS), Fanuc, Yaskawa, Kollmorgen, Baldor, Indramat, and similar industrial drive families. Coverage spans filling, labeling, cartoning, palletizing, and form-fill-seal lines.
Drives come through from Krones, Bosch Packaging, Sidel, Tetra Pak, KHS, IMA, Marchesini, ProMach, R.A. Jones, and other packaging-equipment builders.
No. Hardware repair only. PLC programming, machine commissioning, and line-tuning stay with the customer or integrator. Parameters stored externally must be reloaded after hardware repair.
Yes. Discontinued Indramat DDS / EcoDrive, older Allen-Bradley Ultra series, and legacy Yaskawa Sigma drives come through routinely. The 19,000+ unit donor pool covers a lot of out-of-support hardware.
No. Bench repair is the standard service: ship the drive to Westland, MI for rebuild and testing.
Lead time varies job to job, partly because parts are often pulled from donor boards. Give us a call with the part number and the situation.
One year on parts and workmanship for repairs and rebuilt units. Standard exclusions apply for power surges, contamination, improper installation, and out-of-spec operation.
