2 Maschine information
2.3 Test series on the machine
Prerequisites of the machine
The measurements for condition monitoring assume that the machine axes can be
traversed separately with precisely the motion profile that is defined by the NC
program for performing the measurements.
Machine designs with parallel kinematics, for example, that do not allow this are
not suitable for condition monitoring by ePS Network Services.
Note
Axes that can only be programmed as positioning axes can only undergo the
synchronized axis test. The circularity test or universal axis test cannot be
performed on these axes.
NC programs are downloaded to the control to carry out the axis tests. There must
be approximately 100 KB free NC program memory available.
A variable $AC_MARKER is used for executing the NC programs. You can
configure the variable index. The default setting for the index is value 5. You must
ensure that the $AC_MARKER variable of the configured index is not used by
other control functions.
Note
The ePS system does not check whether the configured $AC_MARKER variable
is also used by other control functions.
