System compatibility

DF900676-C0 belongs to Yaskawa legacy CNC system family,matched with old Yaskawa CNC controllers and CACR-SR series servo drives. Widely used in machining centers,precision lathes and special automation equipment. This is a discontinued legacy power supply board for old production line maintenance spare replacement.

Function

DF900676-C0 serves as high precision CNC power supply board. It converts AC input into multiple groups of stable DC power for CNC main board,IO board and graphic board. Built-in multi-level hardware protection to prevent voltage abnormality damage to other boards. It supports continuous stable power output during machine operation.

Installation

Mount DF900676-C0 inside CNC controller unit. Complete AC input and backplane power wiring according to wiring drawing. Check output voltage after power on before loading other boards.

Interface

‑AC power input connector

‑Multi-channel DC power output port

‑CNC backplane power bus interface

‑Onboard voltage sampling and protection circuit

Circuit feature

Compact rugged PCB layout,equipped with surge and ESD suppression circuit. Fast overcurrent cut-off response,strong anti-interference performance for industrial cabinet environment. Standard factory firmware preloaded.

Feature

DF900676-C0 is obsolete Yaskawa CNC series spare part. Typical failures include capacitor aging,output short circuit,voltage instability. Check board integrity and capacitor status before replacement. This board must match corresponding Yaskawa CNC system,direct substitution without voltage test is not recommended.

Diagnostic

When overvoltage,undervoltage,overcurrent or short circuit occurs,the board triggers corresponding alarm codes and sends fault signal to upper CNC controller.

Built‑in function

AC to DC power conversion,multi-channel stable power supply,voltage fault monitoring,overcurrent protection for CNC control system,used as CNC power supply board spare replacement.

Product Brief

DF900676-C0 (JANCD-PW01) is Yaskawa CNC series power supply board for dedicated machine tool and precision automation machinery. Confirm CNC system model matching before ordering. ESD protection required during handling and installation.
