JANCD-XCP01B is VME bus main CPU control board exclusively for Yaskawa Motoman XRC robot cabinet. It handles robot trajectory calculation, multi-axis motion scheduling, program execution and full system signal communication for stable operation of legacy industrial manipulators.

JANCD: General circuit board prefix for Yaskawa robot controllersXCP: Main CPU processor board dedicated to XRC robot control system01: First generation hardware platform for XRC seriesB: Standard basic hardware version without enhanced customized circuits

Powered by VME backplane DC5V, maximum power consumption 15W. Equipped with 66MHz Motorola XPC105 processor, 16MB DRAM and 1MB SRAM. Built-in CF card slot for program and parameter storage, matched lithium battery for data retention. Operating temperature 0–55℃, storage temperature -20–70℃, humidity 5%–95%RH non-condensing, IP20 protection grade, standard VME plug-in structure.

VME backplane connector realizes high-speed data exchange with servo drive boards, I/O modules and auxiliary signal boards. Onboard RS232C serial port for equipment debugging and parameter uploading. Supports XIF03-1 daughter card expansion to realize 10/100Mbps Ethernet TCP/IP communication. Onboard LED indicators display power supply, bus running and fault alarm states in real time.

Complete multi-axis robot trajectory interpolation, coordinate transformation and dynamic motion computation. Execute robot teaching programs and process safety interlock, peripheral sensor and auxiliary logic signals. Store system firmware, user operation programs and equipment calibration data. Real-time self-diagnosis for bus disconnection, memory and communication failures, output corresponding alarm codes for rapid troubleshooting. Expandable communication daughter card supports data interaction with external PLC and monitoring equipment.

Matched with Yaskawa XRC robot control cabinet, compatible with Motoman UP, HP, EA series multi-axis industrial robots. Widely used in traditional automated production lines including automobile welding, workpiece handling, component assembly, metal polishing and spraying processing stations, as maintenance spare part for old robotic equipment.

Cut off robot cabinet main power and wait at least 10 minutes for internal capacitor full discharge before plugging or removing the board. Keep control cabinet dry and ventilated to prevent welding fume, oil mist and metal dust from covering circuit traces. Regularly inspect VME backplane connectors for looseness and oxidation. Blow surface dust with dry compressed air every three months. Replace the board promptly if persistent system startup failure or bus communication alarm occurs; replace internal lithium battery regularly to avoid parameter loss after power failure.
