Annex: Principle of Function of the iTNC 530 Control

1.1

Introduction

This chapter gives you block diagrams and brief explanations of the principle of function of the
iTNC 520 control.
Fundamental knowledge about controls, encoders, drives, electronics and mechanics simplifies
error diagnosis and is often indispensible for successful servicing.
Ask your machine manufacturer for detailed or special explanations (e.g., machine functions,
circuit diagram of the machine)!
