670 HEIDENHAIN Technical Manual MANUALplus 620
Rapid traverse for
analog axes
In MP_maxFeedAt9V, enter the rapid-traverse rate to be reached at an
analog voltage of 9 V (e.g. for drives reaching the rapid traverse rate at 6 V,
the corresponding value at 9 V must be calculated by linear calculation).
Adjust the rapid traverse feed rate (v
max
) with the analog voltage at the
servo amplifier.

6.5.1 Central drive
It is possible to use one drive for several or all machine axes. The NC software
allows the user to use the same nominal position value output for more than
one axis (MP_analogOutput).
The PLC basic program for the MANUALplus 620 is already prepared for the
central-drive functionality.
The most important basic requirements for realizing a machine with central
drive:
A common drive package with an analog nominal position value input exists
for all axes.
The machine axes are to be handled as clamping axes by the PLC.
Use the PLC to monitor the drive regarding movement in multiple axes, and
output an error message if necessary.
Please refer to the PLC basic program documentation.
In addition to the PLC, the drive is also monitored by the NC. If the attempt
is made to traverse more than one axis of the central drive group, the
control outputs the error message Analog output of axis [axis] was
assigned twice.
If you are switching from the iTNC 530:
Please note that each axis of the central drive group must be enabled
individually in the SIK. This is different on the iTNC 530, where only one axis
must be enabled in the SIK for all axes belonging to the central drive.
