System compatibility
JANCD-1003E belongs to Yaskawa Motoman MRC robot controller family,matched with MRC series robot systems and supporting servo units. Widely used in old Motoman welding robots,material handling robots and automated production lines. This is a discontinued legacy main CPU board for robot controller maintenance spare replacement.
Function
JANCD-1003E serves as high precision robot main CPU control board. It performs robot forward and inverse kinematics calculation,generates multi-axis synchronous motion trajectory and distributes motion commands to servo control boards. It manages robot system parameters,stores program files and collects alarm signals from IO,spindle and other functional boards. Built-in hardware watchdog circuit to prevent abnormal robot movement. It acts as the core processing unit of Motoman MRC robot controller.
Installation
Mount JANCD-1003E inside robot controller cabinet. Complete backplane bus connection according to wiring drawing. Backup robot programs and system parameters before replacement,verify system boot and axis motion function after power-up.
Interface
‑Robot backplane bus connector
‑Parameter backup battery socket
‑Serial communication port
‑Onboard motion calculation and signal protection circuit
Circuit feature
Compact rugged PCB layout,equipped with surge and ESD suppression circuit. Fast multi-axis calculation response,strong anti-interference performance for industrial cabinet environment. Standard factory firmware preloaded.
Feature
JANCD-1003E is obsolete Yaskawa Motoman series spare part. Typical failures include system boot failure,battery-induced parameter loss,backplane bus communication interruption. Check board integrity and connector pins before replacement. This board must match corresponding Motoman MRC robot controller,direct substitution without parameter backup and function test is not recommended.
Diagnostic
When robot boot failure,program execution error or backplane communication fault occurs,the board triggers corresponding alarm codes and sends fault signal to robot teach pendant.

Built‑in function
Robot kinematics calculation,multi-axis trajectory interpolation,system parameter management,program storage,hardware watchdog monitoring,used as Motoman robot main CPU control board spare replacement.
Product Brief
JANCD-1003E (DF8203498) is Yaskawa Motoman MRC robot series main CPU control board for industrial robots and factory automation equipment. Confirm robot controller model matching before ordering. ESD protection required during handling and installation.
