A20B-2002-0040/07DR Printed Circuit Board

A20B-2002-0040/07DR Printed Circuit Board  

Product Details Introduction

A20B-2002-0040/07DR is the core control PCB within the FANUC Alpha i series servo amplifier. As the "brain" of the amplifier, it is responsible for processing motion control instructions and feedback loops, and is compatible with mid to high end CNC and automation equipment.

Core positioning: Alpha i series servo amplifier main control board, processing high-speed motion commands and converting them into power drive signals

Communication interface: Supports FSSB fiber optic bus, high-speed communication with CNC systems such as FANUC 0i, strong anti-interference ability

Feedback processing: Receive high-frequency feedback signals from the encoder, complete position/velocity closed-loop correction, and ensure positioning accuracy

Hardware configuration: Equipped with a high-speed RISC processor, instruction execution is jitter free, and response speed is fast

Reliability optimization: 07DR version strengthens EMI shielding and signal isolation to resist power module noise interference

Power specification: Operating voltage 24V DC, power consumption compatible with servo amplifier control unit

Protection mechanism: Built in RAM verification, communication timeout, encoder feedback exception and other diagnostic protections

Environmental tolerance: working temperature -20 ℃ to+70 ℃, storage temperature -40 ℃ to+85 ℃, suitable for industrial sites

Structural design: Standard modular layout, supports quick on-site replacement, reduces maintenance downtime

Application scenario: Suitable for FANUC Alpha i series servo drives, used in high-precision scenarios such as CNC machine tools, robots, automated production lines, etc

As a highly integrated and robust servo control core, it is a commonly used main control board for FANUC's high-end automation equipment, balancing stability and maintenance convenience.
