FANUC A06B-6240-H209 Fanuc Drive Core Analysis

1、 Product positioning and functionality

A06B-6240-H209 is a dual axis spindle servo drive launched by FANUC, designed specifically for high-end CNC machine tools, industrial robots, and precision machining equipment

high precision control

By using vector control and field oriented control (FOC) algorithms, precise adjustment of torque, speed, and position can be achieved, with a positioning accuracy of ± 0.001mm.

Supporting a 24 bit high-resolution encoder interface, the encoder feedback accuracy has been improved to 1/16777216 pulses per revolution, meeting the requirements of nanometer level positioning.

Wide dynamic response range

The servo frequency range is 0Hz-550Hz, and the spindle frequency range is 1Hz-1.5kHz. It supports millisecond response speed and is suitable for high-speed machining scenarios.

Multiple protection mechanisms

Built in overload protection, overvoltage protection, short circuit protection, over temperature protection, and encoder disconnection detection ensure stable system operation.

Compatibility and Scalability

Compatible with Fanuc Alpha IF and Alpha IS series high-resolution servo motors (such as Alpha IF: 12/3000, 22/3000; αis:8/4000、 12/4000, etc.).

Support multi-mode switching of position, speed, and torque to meet different processing requirements.

2、 Technical parameters and specifications

The input voltage is three-phase 283V-339V (with a current of 39A at 283V), and the control circuit power supply is single-phase 200V-240V (with an allowable deviation of -15% to+10%).

The maximum output voltage is 240V, the rated output is 200V (three-phase), and the spindle frequency is 1Hz-1.5kHz.

Control modes include position control, speed control, and torque control (supporting multi-mode switching).

The feedback interface is compatible with incremental encoders, absolute encoders, and rotary transformers, and supports high-resolution encoder interfaces.

The working environment temperature ranges from 0 ° C to 55 ° C, with a protection level of IP20 (dustproof design, suitable for installation inside control cabinets).

The external dimensions are 38cm in height, 6cm in width, and 27.2cm in length, with a weight of approximately 4kg. The compact design saves installation space.

Certification standards include CE certification, UL certification, and RoHS certification.
