6.2.3 Measuring function (Servo)
Description
The measuring function is used for optimizing the drive controller. By parameteriz-
ing the measuring function, the impact of superimposed control loops can be sup-
pressed 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 ac-
tual value). The trace function is parameterized automatically when the measuring
function is parameterized. Specific predefined operating modes for the trace func-
tion are used for this purpose.
Parameterizing and using the measuring function
The parameterization and commissioning tool STARTER (see Section 3.2) will help
you parameterize and use the measuring function properly.
