Measuring Function - Siemens SINAMICS S120 Commissioning Manual

Measuring function

Description
The measuring function is used for optimizing the drive controller. By parameterizing the
measuring function, the impact of superimposed control loops can be suppressed selectively
and the dynamic response of the individual drives analyzed. The ramp-function generator
and trace function are linked for this purpose. The control loop is supplied with the ramp-
function generator signal at a given point (e.g. speed setpoint) and recorded by the trace
function at another (e.g. speed actual value). The trace function is parameterized
automatically when the measuring function is parameterized. Specific predefined operating
modes for the trace function are used for this purpose.
Parameterizing and using the measuring function
The measuring function is parameterized and operated via the STARTER commissioning
tool.
