2 Introduction

2.1 General

HEIDENHAIN contouring controls are designed for use with milling, drilling

and boring machines as well as machining centers.

The TNC 426 PB/M, TNC 430 PA/M features integral digital drive control and

controls the power stages via PWM signals.

Integration of the drive controllers in the TNC 426 PB/M, TNC 430 PA/M

offers the following advantages:

nAll of the software is contained centrally in the NC; this means that the

individual components of the NC such as feed axes, spindle, NC or PLC are

optimally matched

nHigh control quality, because the position control, speed control and current

control are combined into one unit.

nFor commissioning, optimization and diagnosis, the same functions are

available both for the feed drive and the main spindle.

The TNC 426 PB offers digital control for machines with up to 5 axes and

spindle speeds up to 12 000 rpm (option: 24 000 rpm).

The TNC 430 PA supports up to 6 digitally controlled NC axis, 3 analog

controlled secondary axes, and digitally controlled spindle speeds up to

24 000 rpm.

April 2000 General 2 – 3

The TNC 426 M offers digital control for up to 5 axes and spindle speeds up

to 12 000 rpm (option: 24 000 rpm).

The TNC 430 M offers digital control for up to six or nine axis and spindle

speeds up to 24 000 rpm.

The TNC 426 M, TNC 430 M is designed for connection of a compact or

modular inverter system. Thus, together with HEIDENHAIN motors, a

complete control package including servo drive can be offered (see Technical

Manual "Inverter Systems and Motors").

The TNC 426 CB is the version of the TNC 426 that is equipped with analog

speed command interface and can control machines with up to five axes plus

spindle.

The TNC 430 CA also has analog speed command interface for machines with

up to eight axes plus spindle. A ninth axis can be controlled with an additional

PCB.
