Foreword

The HEIDENHAIN TNC 122 is a compact, three-axis straight cut control for machine tools with
central drive. It has been developed as the successor model for the TNC 121, to which it is
compatible for installation. The TNC 122 has an expanded range of functions.

This Technical Manual is intended for all machine tool builders and machine tool distributors, and for
retrofitting companies who wish to replaced an installed TNC 121 with a TNC 122. It provides the
information required for mounting, electrical connection and commissioning the control.

For information on the new and improved operating features, please refer to the User's Manual.
