Fanuc Servo Amplifiers

FANUC servo amplifiers drive CNC and robotic axes with the speed, accuracy, and reliability the brand is known for. This collection covers single-, dual-, and triple-axis amplifier modules across common 200 V / 400 V classes, pairing with FANUC αi / βi motor families and modern FANUC controls. You’ll also find spindle amplifiers, power supply / regenerative units, and accessories for clean, serviceable installations.

What you’ll find here

• Servo Amplifier Modules: compact single/dual/triple-axis units for linear/rotary axes.

• Spindle Amplifiers: high-response drives for main spindles and high-speed machining.

• Power & Regen Units: shared DC bus, braking choppers/resistors, and supply modules.

• Cables & Accessories: encoder/fiber links, power jumpers, mounting hardware.

Selection notes (practical)

• Axis & current: choose single/dual/triple by axis count; size by rated output current and motor torque needs.

• Voltage class: match the machine’s 200 V or 400 V system and available mains.

• Control compatibility: confirm with your FANUC CNC/robot controller generation and the required high-speed servo bus.

• Motor family: pair the amplifier with the intended FANUC αi / βi servo motors (and encoder type).

• Energy handling: check for regenerative/brake requirements (duty cycle, decel rates).

• Lifecycle: align firmware/revisions across axes for smooth commissioning and easier field service.
