Programmable readout for up to 6 axes

Heidenhain Positip PT880 

The POSITIP 880 is a versatile display unit designed primarily for milling machines, drilling and boring machines and lathes with up to six axes. A separate I/O unit provides switching input/outputs for simple tasks in automation.


The POSITIP 880 display unit is designed as a sturdy upright unit with splash-proof full-travel keypad for use in the workshop. It supports all operations with straightforward interactive menus on its large, easy-to-read colour flat screen. And it does it on big machines as well: the POSITIP 880 permits the connection of a separate display and control unit; you can have all position values and functions available at a remote console.


The POSITIP provides advanced features beyond those offered by the ND 780 display unit. The POSITIP supports any axis combination and helps you at 2-D machining operations with its graphic contour monitoring and magnify function. In the milling mode it supports you in machining and clearing out rectangular pockets while it takes allowances into account during turning.

The programming capabilities of POSITIP make it ideal for small-batch production on conventional machine tools: you can store up to 999 program blocks per program in its memory. Programs are created by either keying them in step by step or generating them through actual position capture (teach-in programming). With the subprogramming capability, you can enter repetitive machining sequences on the same workpiece once only. Fixed cycles keep your programs short and save you programming time.

Data Interfaces

The POSITIP 880 has an RS-232-C/V.24 serial interface for measured value transfer to a PC or printer, for input/output of parameters and compensation value lists, and for diagnostics.
