YASNAC J50L

DESCRIPTIVE INFORMATION

CNC SYSTEM FOR TURNING APPLI CATIONS

YASUAWA

SIE-C843-12.20

1 INTRODUCTION

The YASNAC J50L is a high-performance CNC for the simultaneous control of

2 or 3 axes of a lathe machining tools, with emphasis placed on high-speed machining, and programming capability.

FEATURES

Ultra-high-speed Performance “High-speed, computing system” is achieved by installing a 32-bit microprocessor in the YASNAC J50L.

Significant Downsizing (miniaturized)

2. YASNAC J50L is significantly downsized because it has surface mounted devices and customized gate arrays.

This manual explains both basic and optional features of

YASNAC J50L as

well as the servo system. You can determine your own hardware requirements after carefully reading this manual.

This manual is subject to change without

notification due to product improvements, model changes, etc.
