A06B-6096-H116 FANUC AC Servo Amplifier Unit A06B6096H116 A06B-6096-H116

FANUC A06B-6096-H116 | Alpha SVM1-130S Single-Axis Servo Module — 35A / 7.5 kW / FSSB HRV3 / αM30/3000

SVM1-130S — 35A for the αM30/3000 Motor Class

The A06B-6096-H116 is the SVM1-130S — the single-axis 35A FSSB servo module in FANUC's A06B-6096 series, sized specifically for the αM30/3000 motor. At 35A continuous output from a 7.5 kW DC bus, this module sits in the heavy-duty range of the 6096 series: enough sustained current for main saddle drives on large vertical machining centres, X-axis carriage drives on heavy horizontal machining centres, and B-axis trunnion drives on five-axis machines where the rotary axis carries significant workpiece mass.

The 60mm module width for a 35A output is achieved through a 150A-class IPM (Intelligent Power Module) — a single high-current device that integrates the three-phase bridge, gate drivers, and protection circuits in one package. The external heatsink at the rear of the module (adding 307mm total depth) handles the IPM's thermal output, supplemented by the internal fan

Key Specifications

SVM1-130S vs SVM1-130 — Why the Suffix Matters

The A06B-6096 series contains both the SVM1-130S (H116, 35A) and the SVM1-130 (H106, 52.2A). The "130" in both designations identifies the transistor internal current class — not the module's output current. The H116 at 35A is sized for αM30-class motors; the H106 at 52.2A covers αM40 or α40-class motors. Both use 150A-class IPM transistors but are parameterised and rated differently.

These modules are not substitutable. Their control cards differ and the motor parameters are class-specific. When replacing a failed SVM1-130S, confirm the H116 part number specifically — not H106.

HRV3 — Higher Current Control Bandwidth

HRV3 (High Response Vector 3) is FANUC's third-generation current control algorithm, available on 30i/31i/32i controls and i-Series controls with the HRV3 software option. It provides tighter current waveform quality at the motor terminals compared to HRV1 or HRV2, reducing torque ripple at machining speeds. On heavy-axis drives like the αM30/3000, the improved current regulation produces smoother velocity through contouring moves and better surface finish on arc and corner transitions.

Without the HRV3 software option at the CNC, the module operates at the HRV level the control supports — HRV3 is a CNC software capability, not a hardware incompatibility. The module is compatible with all FSSB i-Series controls regardless of HRV level.

FAQ

Q1: What is the difference between SVM1-130S (H116, 35A) and SVM1-130 (H106, 52.2A)?

Both share the "130" transistor class designation, but their output currents, control cards, and motor parameter configurations differ. H116 is sized for αM30-class motors at 35A; H106 is sized for αM40-class at 52.2A. These are electrically distinct and not interchangeable. Confirm the installed module is H116 before ordering.

Q2: The module dimensions are 380 × 60 × 307mm — how does the 307mm depth affect installation?

The 307mm depth includes the external heatsink that projects from the rear. In standard Alpha module cabinet installations, the heatsink passes through the cabinet rear panel into the cooling duct or free-air space. The cabinet panel must accommodate the full 307mm depth plus heatsink clearance for airflow. Blocking heatsink airflow produces thermal overload alarms.

Q3: What CNC controls support HRV3 capability with this module?

HRV3 is available on FANUC 30i-B, 31i-B, 32i-B and later, and on selected 15i/16i/18i/21i controls with the HRV3 software option. On controls without the option, the module operates at HRV1 or HRV2. HRV3 capability is a CNC software feature — the module is hardware-compatible with all FSSB i-Series controls.

Q4: What causes Alarm 466 on this module and how is it diagnosed?

Alarm 466 is a high-current alarm on the L-axis, typically triggered by motor cable insulation failure or a winding short. Disconnect the motor power cables and measure winding-to-earth insulation resistance. If the alarm clears with cables disconnected, the motor or cable is the fault source — not the amplifier. Reference the B-65165E maintenance manual for the full alarm code list for this module.

Q5: What are the typical machine applications for the A06B-6096-H116?

The αM30/3000 and SVM1-130S pairing is found on heavy CNC axis drives: X-axis carriage drives on large horizontal machining centres, Y-axis column drives on large vertical machining centres, B-axis trunnion drives on five-axis machines, large CNC grinding machine table drives, and heavy-duty CNC boring mill axes where sustained 35A output is required under full-load cutting conditions.
