Yaskawa Electric Corporation JASP-WRCA01 Servo Control Board

The Yaskawa JASP-WRCA01 (Rev. 03) is a servo control board that sits inside Motoman XRC robot controllers, serving as the servo motion control interface between the controller logic and the servo drives, coordinating how motion commands translate into precise axis actions. As a dedicated Servo Control Board, it handles axis movement coordination, feedback processing, and system communication to maintain accurate positioning of robotic axes across automation tasks such as welding, material handling, and assembly. The device is a printed circuit board assembly installed inside the controller cabinet, with a typical weight of about 1 lb, and is designed for use with Yaskawa Motoman XRC robot controllers to interface controller logic with servo amplifiers. Common replacements include the updated JASP-WRCA01B, and related controller boards such as JARCR-XO01 / XOI01.
