System compatibility

JANCD-1004C belongs to Yaskawa Yasnac CNC controller family,matched with Yasnac old series CNC systems and CACR-SR servo amplifiers. Widely used in CNC lathes,milling machines and machining centers. This is a discontinued legacy servo control board for old machine tool maintenance spare replacement.

Function

JANCD-1004C serves as high precision CNC servo control board. It receives motion trajectory commands from CNC main CPU board,executes real-time servo control calculation and outputs axis motion instructions to servo amplifiers. It collects and decodes rotary encoder feedback signals to feed back axis actual position and speed to CNC host. Built-in signal filtering and ESD protection circuit to suppress industrial site interference. It realizes precise multi-axis positioning and interpolation control for Yasnac CNC machine tools.

Installation

Mount JANCD-1004C inside CNC controller cabinet. Complete backplane bus and encoder wiring according to wiring drawing. Backup CNC servo parameters before replacement,verify servo communication and axis positioning function after power-up.

Interface

‑System backplane bus connector

‑Multi-channel encoder signal port

‑Servo command output terminal

‑Onboard signal decoding and filtering circuit

Circuit feature

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

Feature

JANCD-1004C is obsolete Yaskawa Yasnac series spare part. Typical failures include encoder port pin damage,servo communication dropout,position reading drift. Check board integrity and connector pins before replacement. This board must match corresponding Yasnac CNC controller,direct substitution without servo positioning function test is not recommended.

Diagnostic

When servo position feedback error,axis positioning deviation or hardware communication timeout occurs,the board triggers corresponding alarm codes and sends fault signal to CNC main controller.

Built‑in function

Multi-axis servo motion calculation,rotary encoder signal decoding,position feedback processing,servo command conversion,signal noise filtering,servo fault monitoring,used as Yasnac CNC servo control board spare replacement.

Product Brief

JANCD-1004C is Yaskawa Yasnac CNC series servo control board for CNC machine tools and precision automation equipment. Confirm CNC controller model matching before ordering. ESD protection required during handling and installation.
