This Technical Manual is intended for manufacturers and distributors of machine tools. It contains all
necessary information for assembly, electrical installation, commissioning and PLC-programming for

Whenever HEIDENHAIN improves the hardware or software in these controls you will receive a free
delivery of updated information. Please insert this updated information into your manual without
delay. This will ensure that your manual always reflects the current revision level.
You can use excerpts from this manual for your machine documentation. Enlarging the manual
format (17 cm x 24 cm) by a factor of 1.225 will produce pages in A4 format.
No documentation can be perfect. This manual undergoes continual change and will benefit from
