YASKAWA LASC-100SUB Communication board or feedback interface board

The YASKAWA LASC-100SUB is a specialized circuit board, often referred to as a Sub-Communication Board or Feedback Interface Board,

typically utilized in Yaskawa’s older high-performance drive systems or specific robotic controller architectures (such as the legacy ERC or early MRC systems).

While it is less common in modern DX200 systems, it remains a vital component for maintaining and repairing specialized industrial equipment that requires specific signal synchronization.

Technical Parameter Table

Product Advantages and Features

Noise Immunity: Designed with high-quality shielding and filtering to handle high-frequency signals in electrically noisy industrial environments.

Precision Timing: Capable of processing high-speed feedback signals, essential for accurate positioning in motion control.

Compact Integration: Acts as a “daughterboard,” allowing users to add specific functionality without replacing the entire main controller board.

Legacy Support: Provides critical compatibility for older Yaskawa systems, extending the life of existing machinery.

Application Cases

Synchronized Motion: Used in applications where multiple axes must be perfectly synchronized, such as high-speed labeling or complex robotic welding.

Encoder Feedback: Interfacing high-resolution encoders with the main drive processor for fine-tuned motor control.

Legacy Robot Maintenance: Serving as a replacement part for ERC/MRC robot controllers used in automotive assembly.

Custom CNC Interfacing: Bridging third-party sensors or specialized machine tool signals to the Yaskawa control architecture.
