Yaskawa JANCD-MSV01B Servo control board (also known as command/feedback board)

The YASKAWA JANCD-MSV01B is a specialized Servo Control Board (also referred to as a Command/Feedback Board) used primarily in the Yaskawa Motoman MRC and XRC robot controllers.

It plays a critical role in the motion control loop, acting as the interface between the main CPU and the servo amplifiers that drive the robot’s joints.

Introduction

The JANCD-MSV01B is responsible for processing position feedback from the robot’s encoders and generating the command signals required to move the robot axes with high precision.

It is designed to handle multiple axes (typically up to 6) on a single card, ensuring perfectly synchronized motion across the entire robot arm.

Product Advantages and Features

Synchronized Multi-Axis Control: Manages complex interpolation for all 6 axes simultaneously, ensuring smooth and accurate path following.

High-Resolution Feedback: Built to process high-speed serial encoder data, allowing for sub-millimeter positioning accuracy.

Thermal Stability: Designed with industrial-grade components to maintain timing accuracy even as the controller cabinet heats up during intensive cycles.

Direct Drive Interface: Provides a direct link to Yaskawa’s Sigma-series servo drives, minimizing signal latency.

Easy Diagnostics: Features onboard status LEDs that indicate whether the feedback loop is closed and if the communication with the CPU is healthy.

Application Cases

Robotic Arc Welding: Ensuring the torch follows a programmed path with extreme precision to maintain weld bead quality.

Waterjet/Laser Cutting: Maintaining constant speed and trajectory for clean cuts in complex 3D shapes.

Heavy-Duty Palletizing: Controlling the acceleration and deceleration of high-inertia loads to prevent mechanical wear and spilling.

Automotive Painting: Coordinating the arm movement with the flow rate of the paint spray for even coverage.
