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 620/640 (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 620/640 complies with the limits
for a 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 548328-03
The simulation function now also provides a 3-D view of the
workpiece blank and finished part. Workpieces can be depicted as a
solid-body model or transparent. The graphic can be both rotated
around the main axes and displayed in a three-quarter section view
(see the User’s Manual).
Simplified contour editing with ICP: When graphically supported
interactive contour description with ICP is active, contour-element
editing can now be selected directly by soft key (see the User’s
Manual).
Recessing with cut segmentation: Cut segmentation for recessing
depth is now available for the contour recessing cycle G860. (see
page 71)
The parameters XA and ZA (starting point of blank) were added to
the roughing cycles G810, G820, G830 and G835. This makes it
possible to start the cutting process at any desired diameter of the
contour by entering a starting point. (see page 60)
Workpiece measurement: The Control now supports workpiece
measurement with touch probes. A sample cycle for measurement
of workpieces is available in the control. Additionally, the machine
manufacturers can offer specially developed measuring cycles that
are individually adapted to the machine series (see the User’s
Manual).
A speed limit that is only effective for the respective cycle can now
be defined for the parting cycle in Teach-in mode and smart.Turn
(see page 75)
In the roughing and drilling cycles, an intermittent feed rate can now
be entered for chip breaking. (see page 60)
The approach angle and departure angle have been added to the ICP
cutting cycles. (see page 65)
The graphic window can now be activated automatically when the
cursor is located in the contour description. (see page 44)

New functions of software 688945-02 and 548328-04
In the program simulation, the current contour description (of
workpiece blank and finished part) can be mirrored and saved. In
smart.Turn, these contours can be reinserted (see User's Manual)
On machines with counterspindle, the workpiece spindle can now
be selected in the TSF menu (see User’s Manual)
On machines with a counterspindle, it’s datum can be shifted (see
User’s Manual)
The user documentation is now also in the context-sensitive help
system TURNguide (see User’s Manual)
You can make your own project folder in the project management,
so that you can centrally manage associated files (see User’s
Manual)
With a manual tool change system it is possible to insert tools that
are not in the turret during a program run (see User’s Manual)
Engraving cycles are now available in the Teach-In mode of
operation (see User’s Manual)
During tool data backup, you can now select in a dialog window the
data to be saved or restored (see User’s Manual)
The G30 function is now available for converting G functions, M
functions or spindle numbers, as well as for mirroring traverse paths
and tool dimensions (see "Converting and mirroring G30" on page
378)
The "traverse to a fixed stop" function (G916) is now available for
transferring the workpiece to the second traversable spindle or for
pressing the tailstock against the workpiece.(see "Traversing to a
fixed stop G916" on page 382)
The G925 function makes it possible to define and monitor the
maximum contact force for an axis. This function can be applied to
use the opposing spindle as a mechatronic tailstock, for example
(see "Force reduction G925" on page 385)
Controlled parting using servo-lag monitoring (G917) can now be
activated to prevent collisions caused by incomplete parting
processes.(see "Controlled parting using lag error monitoring G917"
on page 384)
HEIDENHAIN MANUALplus 620, CNC PILOT 620/640 5
The spindle synchronization option G720 synchronizes the shaft
speeds of two or more spindles so that they rotate synchronously
with a gear ratio or a defined offset.(see "Spindle synchronization
G720" on page 380)
In combination with the synchronization (G720) of main spindle and
tool spindle, the new "Hobbing" cycle (G808) is available for milling
external teeth and profiles.(see "Hobbing G808" on page 520)
With G924, a "fluctuating speed" can now be programmed to
prevent resonance (see "Fluctuating spindle speed G924" on page
374)

New functions of software 548328-05, 54843x-01, 688945-03 ad 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 558).
The control now provides numerous touch probe cycles for various
applications (see "General information on touch probe cycles
(software option)" on page 430):
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
530).
The G940 function 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 375)
For machining operations that require rechucking, you can define a
separation point on the contour description with G44 (see
"Separation point G44" on page 215).
The G927 function enables you to convert tool lengths to the
reference position of the tool (B axis = 0) (see "Convert lengths
G927" on page 375).
Recesses that were defined with G22 can now be machined with
the new Cycle 870 ICP Recessing (see ""ICP recessing" unit" on page
77).
