12.33 Description of function of current and speed setpoint filters12.33.1 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.
