FANUC A06B-6058 A06B-6058-H003 control unit retrofit

The Fanuc A06B-6058-H003 is a digital AC servo amplifier of the S-Series designed for the precise control of Fanuc AC servo motors in industrial CNC applications. The unit operates on a three-phase input voltage of 200 to 230 volts at 50 or 60 Hz and delivers a rated output current of 12.5 amperes. Using PWM inverter technology, the amplifier enables highly precise torque and speed control with fast signal processing via a digital interface. The A06B-6058-H003 is designed for use in Fanuc CNC systems of the 0i, 16i, 18i, 21i, and Power Mate series. It is compatible with Fanuc AC servo motors of the 0S, 5S, and 10S models as well as Model 1-0S and 2-0S, and is suitable for feed and spindle axes in CNC machining centers and machine tools. Integration is achieved via a digital interface to the CNC controller through a backplane or ribbon cable; mounting is via DIN rail or panel mounting inside the CNC cabinet. The unit features a protection rating of IP00 and is intended for direct installation in enclosed control cabinets. Heat dissipation is provided by an integrated heat sink. Operating temperature is specified from 0 to 55 °C, with a storage temperature range of -20 °C to 60 °C. Power loss is approximately 65 watts. The module supports regenerative energy, dynamic braking, and parameter tuning via CNC parameters, as well as diagnostic functions via alarm codes and LEDs. Weight is approximately 1.87 kg in a compact design for standard enclosures.
