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) 548430-02
MANUALplus 620E (HEROS 5) 548431-02
CNC PILOT 640 (HEROS 5) 688946-02
CNC PILOT 640E (HEROS 5) 688947-02
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 Control on your
machine tool.
Some of the Control functions which 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 Control 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.

Intended place of operation
The MANUALplus 620, CNC PILOT 640 complies with the limits for
Class A devices in accordance with the specifications in EN 55022,
and is intended for use primarily in industrially-zoned areas.

New functions of software 54843x-01 and 688946-01
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 562).
The control now provides numerous touch probe cycles for various
applications (see "General information on touch probe cycles
(software option)" on page 428):
Calibrating a touch trigger probe
Measuring circles, circle segments, angle and position of the C
axis
Misalignment compensation
Single-point and double-point measurements
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
528).
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 373)
For machining operations that require rechucking, you can define a
separation point on the contour description with G44 (see
"Separation point G44" on page 213).
G927 enables you to convert tool lengths to the reference position
of the tool (B axis = 0) (see "Convert lengths G927" on page 373).
Recesses that were defined with G22 can now be machined with
the new Cycle 870 ICP Recessing (see ""ICP recessing" unit" on page
75).
4
New functions of software 68894x-02 and 54843x-02
The miscellaneous function "Shift zero point" was introduced in ICP
(see User's Manual)
In ICP contours, you can now calculate fit sizes and internal threads
using an input form (see User's Manual)
The miscellaneous function "Duplicate in linear/circular series, and
by mirroring" was introduced in ICP (see User's Manual)
The system time can now be set using an input form (see User's
Manual)
The parameters K, SD and U have been added to parting cycle G859
(see User's Manual)
The angle of approach and departure can now be defined for ICP
recess turning (see User's Manual)
With TURN PLUS you can now also create programs for machining
on the opposing spindle and for multipoint tools (see "Full-surface
machining with TURN PLUS" on page 556)
It is now also possible to select a milling contour in G797 "Area
milling" (see "Area milling, face G797" on page 343)
The parameter Y was added to G720 (see "Spindle synchronization
G720" on page 378)
The parameters O and U were added to G860 (see "Recessing
G860" on page 273)
