System compatibility

DF9201455-B0 belongs to Yaskawa legacy robot MRC controller family,matched with Yaskawa MRC robot controllers and CACR-SR servo drives. Widely used in welding robots,material handling robots and precision automation equipment. This is a discontinued legacy absolute encoder memory board for old robot production line maintenance spare replacement.

Function

DF9201455-B0 serves as high precision robot ABSO memory board. It stores absolute encoder position data for each robot axis,built-in lithium battery to retain position data when main power is cut off. It transmits absolute position information to robot main CPU during power-up initialization,prevents robot origin loss after power failure.

Installation

Mount DF9201455-B0 inside robot controller cabinet. Complete backplane bus connection according to wiring drawing. Check battery voltage before replacement,perform robot origin calibration after power on.

Interface

‑Robot backplane bus connector

‑On-board lithium battery holder

‑Status indicator LED

‑Onboard position data backup circuit

Circuit feature

Compact rugged PCB layout,equipped with surge and ESD suppression circuit. Low power consumption for battery backup,strong anti-interference performance for industrial cabinet environment.

Feature

DF9201455-B0 is obsolete Yaskawa MRC robot series spare part. Typical failures include lithium battery depletion,absolute position data loss,bus communication dropout. Check board integrity and battery status before replacement. This board must match corresponding Yaskawa MRC robot controller,direct substitution without origin reset is not recommended.

Diagnostic

When battery low alarm,absolute position data loss or bus communication interruption occurs,the board triggers corresponding alarm codes and sends fault signal to robot main controller and teach pendant.

Built‑in function

Multi-axis absolute position storage,battery data backup,position data upload at startup,battery low level monitoring,used as robot ABSO absolute encoder memory board spare replacement.

Product Brief

DF9201455-B0 (JANCD-MFC04) is Yaskawa MRC robot series ABSO absolute position memory board for industrial robot and precision automation machinery. Confirm robot controller model matching before ordering. ESD protection required during handling and installation.
