10.5 Measuring function for coupled axes
Composite axes were not supported by the previous “Measuring function” and
“Function generator” start-up aids. With version 5 of the software package, the
existing HMI user interface has been upgraded:
it is now possible to easily optimize by scanning individual axes. This is done by
setting certain “measuring parameters”.
The upgraded HMI user interface allows the start-up engineer to scan each
individual axis
S of the Composite gantry
S the coupled master and slaves (from software version 6.4)
S and mixed master–slave combinations coupled to gantry axes (from soft-
ware version 6.4 )
with due regard to the permitted measuring parameters.
The HMI programs the axes with the same values so that they perform identical
movements.
The user can record the results for one or 2 axes at the same time. This corre-
sponds to the previous measuring function for 2 independent axes. With mixed
coupled units, the leading axis always taken from the gantry composite axis. All
further axes are then synchronizing axes with the same parameters.
The HMI user interface provides further measuring functions as aids to start-up.
Soft keys can be used to determine whether a certain axis configuration should
be used for scanning in the

10.5.1 Interconnected gantry axes only or master–slave couplings
The Function generator and Measure start-up functions are still programmed via
PI services. The traversing motion is started for all programmed axes by pres-
sing the MSTT button NC-Start in JOG operating mode.
On the “Function generator in interconnected gantry” screen, the user interface
displays an image in which you can enter 2 amplitude values and a period dura-
tion, pulse width, offset and limitation.
On the “Measuring function in interconnected gantry” screen, in addition to the
2 amplitude values, you can enter a bandwidth, averaging, settling time and an
offset. The first amplitude value applies to the measured access and the second
to the other, coupled axes.
