FANUC parts & electronics

Regarding factory automation, you will likely need help finding a source more prolific than FANUC. In addition, along with being the biggest supplier of industrial robots in the world, FANUC electronics parts include a wide collection of servo system parts. This includes servo motors, servo drives, servo amplifiers, servo amp modules, servo converters, spindle drives, and spindle amps.

To help your business better automate your operations, Industrial Automation is ready to supply your company with high-quality FANUC parts. This includes recent parts and several parts that the manufacturers have discontinued. Check out our full FANUC parts catalog, or contact us today to find what you’re looking for.

FANUC Product FAQ — Servo Amplifiers, CNC Controls & Feedback Systems

Can FANUC servo amplifiers be replaced without changing the motor or controller?
Yes — as long as the amplifier series, current rating, and encoder feedback type are compatible. We confirm firmware revision and model alignment before approving a replacement.

Can FANUC CNC control boards be replaced without reloading ladder or machine parameters?
Only when board type, control series, and memory configuration match the original hardware. In some cases, ladder logic or machine parameters may need to be reloaded.

Can a FANUC servo motor be paired with a different FANUC amplifier model?
Often — as long as motor capacity, encoder specification, and feedback resolution match the drive’s requirements. We verify motor/amplifier pairing for safe operation.

Are FANUC power supply modules interchangeable across CNC generations?
Only within compatible control families. Connector interface, rated current, and alarm protocol must align with the CNC system.

Can FANUC encoder or feedback cables be replaced with third-party versions?
Only if shielding, impedance, and pin configuration match FANUC specifications. Feedback signal integrity must meet CNC noise-tolerance requirements.

Can you replace a FANUC amplifier while keeping the same motor?
Yes — we match amplifier series and feedback type so your existing servo motor operates correctly.

Can you replace a FANUC CNC board without losing parameters?
Yes — when the correct board type and memory format are selected. We help ensure parameter retention with minimal rework.

Can a FANUC motor be replaced while reusing the original amplifier?
Often — we verify encoder type, continuous current rating, and feedback resolution for compatibility.

Can you replace a FANUC power supply module from an older machine?
Yes — we match connector style and current capabilities to ensure seamless controller integration.

Can FANUC encoder cables be swapped without introducing noise?
Yes — as long as EMI shielding, grounding, and pin mapping match the original FANUC spec.
