Product Introduction

nuc is a robust AC servo amplifier designed to deliver exceptional motion control performance in demanding CNC and industrial applications. Utilizing advanced sinusoidal PWM control and high-speed current/voltage closed-loop feedback, this drive ensures minimal torque ripple, rapid acceleration, and micron-level positioning accuracy.

As a critical component of Fanuc’s servo e seamlessly interfaces with high-precision encoders to provide reliable closed-loop position and speed control. Whether driving ball screws for machining centers or rotary tables for automated assembly, this amplifier provides the stable power and dynamic response required for high-quality manufacturing.

 

QA & Testing SOP

Servo amplifiers require rigorous validation of their power stages and control logic. We verify both electrical integrity and dynamic performance.

1. Anti-Counterfeit & Visual Audit: We inspect the Fanuc silkscree part number, and check power terminals, motor connectors, and feedback ports for physical damage or corrosion.
2. DC Bus & Power Stage Test: We apply input power and verify the internal DC bus charges correctly, testing the IGBT modules and rectifier bridge for shorts or leakage.
3. Control Logic Validation: Using a Fanuc test controller, we verify the amplifier correctly enumerates, accepts speed/position commands, and responds to feedback signals.
4. Cooling System Check: We verify the internal cooling fan operates at the correct RPM and that airflow paths are unobstructed.
5. ESD Safe Packaging: Sensitive servo control ASICs are highly ESD sensitive. We pack in anti-static shielding with desiccant to prevent latent semiconductor damage.

Installation Pitfalls & Guide

❗ Parameter Matching: After installation, you must verify that the servo parameters (motor ID, gear ratio, feedback type) match the connected motor and mechanical system. Incorrect parameters will cause “Parameter Error” alarms or uncontrolled motion.

❗ Heat Dissipation: Servo amplifiers generate significant heat during operation. Ensure the control cabinet has adequate airflow and that the ambient temperature does not exceed specifications. Never block the intake/exhaust vents.

❗ Feedback Wiring: Encoder and feedback cables carry microvolt-level signals. Route them separately from high-current motor power cables to prevent electromagnetic interference (EMI) from causing position errors or alarms.

❗ Grounding: The amplifier chassis must be properly grounded to the system ground with a thick, short copper strap. Poor grounding causes erratic alarms, communication errors, and potential damage to internal components.

Replacement SOP:

1. Pre-Install: Record all servo parameters from the old amplifier or CNC backup; power down and lock out the main input.
2. Removal: Disconnect motor power, encoder cables, and control bus; remove mounting screws and extract the module.
3. Install: ; reconnect all power and feedback cables; verify connections are secure.
4. Power-On Test: Apply control power first; verify no immediate alarms; apply main power; initialize parameters if prompted; run a low-speed jog test before removing bypass.

 

Technical FAQ

What motors are compatible with this amplifier?
The is designed to work with Fanuc AC servo motors, including the AC0, 5, 10, 20M, 20, 30, and 30R series, as well as αi series motors with high-resolution encoders. Always verify the motor ID matches the amplifier configuration.

What are the most common alarms for this model?

• Overcurrent/Overload: Check motor cables for shorts, verify mechanical load, and inspect IGBT modules.
• Overvoltage: Check DC bus voltage, braking resistor, and input power supply.
• Encoder/Feedback Error: Check encoder cable, shielding, and motor feedback connector.
• Parameter Error: Verify motor code and gear ratio settings match the physical motor.

Can this amplifier be used with non-Fanuc motors?
While technically possible with extensive parameter tuning, it is not recommended. Fanuc amplifiers are optimized for their own motors’ feedback devices and electrical characteristics. Using third-party motors may result in poor performance, tuning difficulties, and voided warranties.

Is this compatible with modern Fanuc 0i-F or 30i systems?
The series is typically associated with older Fanuc systems (0, 11, 15 series). Newer systems like 0i-F and 30i generally use βi or αi series amplifiers. Always verify compatibility with your specific CNC system generation before purchasing.

Why is this sold as new surplus?
This unit was pulled from sealed OEM overstock or an unfulfilled machine build project before installation. We test it on our Fanuc test benches to verify power stage and logic functionality, but we aren’t replacing internal components. You are getting unused factory hardware with original manufacturing tolerances at a fraction of the active OEM list price.
