A06B-6127-H106 is a single-axis 400V class Alpha i high voltage servo amplifier. It is designed for heavy load and high power CNC axis control, and needs to be used together with matched αi PSM power supply module.

Part number is A06B-6127-H106 with model code αiSV-180HV. It belongs to Alpha i series and manufactured by FANUC. This drive applies to high power servo axes of heavy-duty machining centers, lathes and industrial automation equipment.

DC bus input voltage ranges from 565V DC to 679V DC. Rated input power reaches 32kW. External 24V DC power with ten percent voltage tolerance supplies power for control circuit, FSSB communication and cooling system.Three-phase rated output voltage is 480V AC. Rated RMS output current is 58A and peak current is 180A. The maximum output frequency can reach 400Hz. Full digital vector control supports position, speed and torque working modes. Regenerative braking function transmits redundant operating energy back to DC bus loop.

The unit adopts yellow metal shell and vertical panel installation structure equipped with high efficiency heat sink. Overall dimension width 150mm, height 290mm, depth 380mm. Net weight ranges from 10.7kg to 13.0kg. Cooling system is composed of replaceable axial fan and heat dissipation module.Operating temperature is within 0 degree Celsius to 55 degree Celsius without condensation. Storage temperature covers minus 20 degree Celsius to 60 degree Celsius. Operating relative humidity keeps 5 percent to 95 percent non-condensing environment. Protection grade is IP20, suitable for installing inside electrical cabinet.

It matches FANUC αi HV series servo motors. Corresponding supporting power supply is 400V grade αi PSM module. Applicable CNC control systems include FANUC 30i, 31i, 32i-B and 0i-MF, 0i-TF with 400V power configuration. The amplifier adopts high speed FSSB fiber communication bus. It is compatible with absolute and incremental encoder signals. Built-in backup capacitor maintains axis position data steadily, no homing operation required after equipment replacement.

Overcurrent failure triggers alarm code AL-01. DC bus undervoltage and overvoltage faults correspond to AL-04 and AL-07 separately. Heat sink overheat protection outputs AL-03 alarm, and fan abnormal condition displays AL-02. The device can also detect encoder communication error and regenerative overload fault. The seven segment LED indicator on front panel displays real-time running status and failure codes.

Cut off all system power and implement safety lockout procedure before installation work. Mount the amplifier vertically and keep enough ventilation space around the device. Connect DC bus cable to matched αi PSM module and finish reliable protective grounding. Wire 24V control power and FSSB optical fiber cable strictly following official wiring standard. Check all connection tightness and eliminate historical alarms before power supply recovery.

High voltage exists inside the amplifier interior. Staff shall not open the outer cover within ten minutes after power cut off. All installation, wiring and maintenance work must be completed by qualified professional electricians. Only original FANUC matched cables and connectors can be adopted. Clean dust on fan and heat sink regularly to maintain stable heat dissipation performance.

High 32kW rated power and 58A output current satisfies heavy load machining working requirements. Solid mechanical structure ensures stable long-time operation. Built-in position data backup capacitor simplifies equipment replacement process. Fiber signal transmission possesses fast response speed and strong anti-interference ability. Multiple safety protection mechanisms effectively reduce unexpected shutdown risks.
