System compatibility

G86201-1A belongs to Yaskawa legacy robot MRC controller family,matched with Yaskawa MRC robot controllers and CACR-SR servo amplifiers. Widely used in Motoman welding robots,material handling robots and precision automation equipment. This is a discontinued legacy main control board for old robot production line maintenance spare replacement.

Function

G86201-1A serves as high precision robot main CPU control board. It completes robot kinematics solving and continuous trajectory planning,distributes real-time synchronous motion commands to each axis servo amplifier. Built-in hardware watchdog circuit to prevent abnormal robot movement. It runs robot teaching programs and collects alarm and status signals from each functional board inside controller.

Installation

Mount G86201-1A inside robot controller cabinet. Complete backplane bus connection according to wiring drawing. Backup robot axis parameters and program before replacement,download and verify program data after installation.

Interface

‑Robot backplane bus connector

‑Mechatrolink servo command port

‑Serial communication port

‑Onboard motion calculation CPU 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

G86201-1A is obsolete Yaskawa MRC robot series spare part. Typical failures include CPU hardware anomaly,bus communication dropout,robot program parsing failure. Check board integrity and connector pins before replacement. This board must match corresponding Yaskawa MRC robot controller,direct substitution without parameter backup is not recommended.

Diagnostic

When bus communication interruption,hardware watchdog timeout or program loading error occurs,the board triggers corresponding alarm codes and sends fault signal to robot main controller and teach pendant.

Built‑in function

Robot kinematics and trajectory calculation,multi-axis synchronous motion control,robot program operation,system hardware fault monitoring,used as robot main CPU control board spare replacement.

Product Brief

G86201-1A (JANCD-CP05) is Yaskawa MRC robot series main CPU control board for industrial robot and precision automation machinery. Confirm robot controller model matching before ordering. ESD protection required during handling and installation.
