Description of function of current and speed setpoint filters
12.33.1
Introduction
Owing to the complexity of setpoint filter applications, it is not possible to describe their scope
of application in general terms at this point. The following section does, however, specify the
criteria for selecting and parameterizing such filters.
We would recommend our drive system training courses to those interested in understanding
the full range of possible applications for setpoint filters on mechanically critical machines.
Note
The sequence of operations for this function is described in Sections 9.1 and 9.2 in this
documentation.
General application criteria
Filters are used
•
to smooth the response curve
•
to dampen mechanical resonance and
•
to symmetrize axes with different dynamic response characteristics, especially in the case
of interpolating axes.
