This manual describes functions and features provided by lathe
controls as of the following NC software numbers.
Control NC software number
MANUALplus 620 (HEROS 5) 548430-03
MANUALplus 620E (HEROS 5) 548431-03
CNC PILOT 640 (HEROS 5) 688946-03
CNC PILOT 640E (HEROS 5) 688947-03
The suffix E indicates the export version of the control. The export
version of the control has the following limitations:
Simultaneous linear movement in up to 4 axes
HEROS 5 identifies the new operating system of HSCI-based controls.
Machine operation and cycle programming are described in the
MANUALplus 620 (ID 634864-xx) and CNC PILOT 640 (ID 730870-xx)
User's Manuals. Please contact HEIDENHAIN if you require a copy of
one of these manuals.
The machine manufacturer adapts the features offered by the control
to the capabilities of the specific machine tool by setting machine
parameters. Therefore, some of the functions described in this manual
may not be among the features provided by the Steuerung on your
machine tool.
Some of the Steuerung functions that are not available on every
machine are:
Positioning of spindle (M19) and driven tool
Operations with the C or Y axis
Please contact your machine manufacturer for detailed information on
the features that are supported by your machine tool.
Many machine manufacturers and HEIDENHAIN offer programming
courses. We recommend these courses as an effective way of
improving your programming skill and sharing information and ideas
with other Steuerung users.
HEIDENHAIN also offers the DataPilot programming station for PCs,
which is designed for use with the respective control. The DataPilot
is excellently suited for both shop-floor programming as well as offlocation program creation and production planning. It is also ideal for
training purposes. The DataPilot can be run on PCs with WINDOWS
operating systems.

New functions of software 54843x-01 and 68894x-01
On machines with a B axis it is now also possible to drill, bore, and
mill in oblique planes. In addition to this, the B axis enables you to
use tools even more flexibly during turning (see „Tilted working
plane” on page 584).
The control now provides numerous touch probe cycles for various
applications (see „General information on touch probe cycles
(software option)” on page 454):
Calibrating a touch trigger probe
Measuring circles, circle segments, angle and position of the C
axis
Misalignment compensation
Single-point and double-point measurement
Finding a hole or stud
Zero point setting in the Z or C axis
Automatic tool measurement
The new TURN PLUS function automatically generates NC
programs for turning and milling operations based on a fixed
machining sequence (see „TURN PLUS mode of operation” on
page 552).
G940 now provides a way to calculate the tool lengths in the basic
(definition) position of the B axis (see „Calculate variables
automatically G940” on page 385)
For machining operations that require rechucking, you can define a
separation point on the contour description with G44 (see
„Separation point G44” on page 222).
G927 enables you to convert tool lengths to the reference position
of the tool (B axis = 0) (see „Convert lengths G927” on page 385).
Recesses that were defined with G22 can now be machined with
the new Cycle 870 ICP Recessing (see „"ICP recessing" unit” on
page 79).
