Machine data must be set in the control to acquire data for the condition monitoring
measurements. Not only Trace Server machine data but also MD 36730:
DRIVE_SIGNAL_TRACKING must be set.
Drives that are linked via Profibus must be handled differently. Here the Profibus
configuration must be changed so that the torque values can be transmitted to the
control cyclically.
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 pro-
gram 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 per-
formed 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 config-
ure 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.
