Product Overview
When a high-precision robotic arm in a CNC machining center experiences torque ripple during rapid acceleration, the FANUC A06B-6117-H202 Servo Amplifier Module steps in to deliver smooth, stable power. This module is engineered for demanding motion control tasks where accuracy and reliability are non-negotiable. As part of the FANUC A06B product line, it integrates seamlessly into multi-axis servo systems, providing dedicated current control for both L-axis and M-axis motors.
Technical Specifications Breakdown
The A06B-6117-H202 operates with a DC input voltage range of 283 to 339 VDC, ensuring compatibility with common industrial DC bus architectures. Its rated input power is 0.32 kW, making it suitable for medium-duty servo applications. The module converts this to a three-phase AC output of 200 to 240 VAC, with an output frequency range spanning 0.1 to 800 Hz. This wide frequency band allows precise speed and position control across diverse motor types.
Current ratings are split per axis: the L-axis delivers a rated output current of 1.5 A, while the M-axis provides 3 A. This dual-axis capability simplifies wiring and reduces cabinet space in multi-axis systems. The module weighs 11.00 lbs (4.99 kg), a compact form factor for its power class.
Industry Applications
In automated assembly lines, the A06B-6117-H202 excels at controlling servo motors for pick-and-place operations. The wide output frequency range (0.1-800 Hz) enables both slow, precise movements and high-speed transfers without changing hardware. For example, in a packaging machine, the L-axis (1.5 A) can manage a label applicator while the M-axis (3 A) drives a conveyor belt, all from one amplifier. This reduces component count and simplifies troubleshooting.
Another common use is in CNC milling machines, where the module powers axis drives that require tight synchronization. The robust environmental tolerance—operating from 0°C to 55°C and up to 90% relative humidity without condensation—ensures reliable performance even near coolant mist or in unheated factory floors.
Installation & Setup Guidance
Mount the A06B-6117-H202 on a flat, vertical surface inside a clean, dry electrical cabinet. Ensure adequate airflow around the heatsink; the module dissipates heat during operation. Connect the DC input bus (283-339 VDC) using appropriately rated cables, observing polarity. The AC output terminals (200-240 VAC) should be wired to the servo motors with shielded cables to minimize electromagnetic interference. Set the input frequency to 50 or 60 Hz as per your local mains supply. Always verify that the total load current does not exceed 1.5 A on the L-axis or 3 A on the M-axis.
Maintenance & Reliability
Periodically inspect the module for dust buildup on the heatsink and cooling fan (if present). Clean with low-pressure dry air to prevent overheating. Check all terminal connections for tightness annually. The module's wide operating temperature range (0°C to 55°C) and high humidity tolerance (90% RH) reduce the risk of condensation-related failures. By keeping the cabinet environment within these limits, you extend the service life and minimize unplanned downtime.
Buying Guide & Selection Advice
Before purchasing, confirm that your system's DC bus voltage falls within 283-339 VDC and that your motor's rated current matches the axis-specific outputs (1.5 A L-axis, 3 A M-axis). Verify the output voltage requirement (200-240 VAC) and frequency range (0.1-800 Hz) align with your motor's specifications.

Frequently Asked Questions
Q: Can the A06B-6117-H202 drive two motors simultaneously?
A: Yes, it supports dual-axis control: the L-axis provides 1.5 A and the M-axis provides 3 A, allowing independent operation of two servo motors.
Q: What is the maximum ambient temperature for safe operation?
A: The module operates reliably from 0°C to 55°C. Ensure the cabinet temperature stays within this range to avoid thermal shutdown.
Q: Does the module require a separate power supply?
A: It requires a DC input of 283-339 VDC, typically from a common DC bus or a dedicated rectifier. The input frequency is 50/60 Hz for the mains side.
Q: What is the output frequency range for speed control?
A: The output frequency spans 0.1 to 800 Hz, enabling precise speed regulation from near-zero to high-speed operation.
Q: Is this module compatible with older FANUC servo motors?
A: Compatibility depends on motor voltage and current ratings. Verify that your motor's rated voltage is 200-240 VAC and current does not exceed 1.5 A (L-axis) or 3 A (M-axis).
