Suppression Bandwidths And Setpoint Limits - Siemens SINAMICS S120 Function Manual

Suppression bandwidths and setpoint limits

In the range from 0 rpm to the speed setpoint, a drive train (e.g. motor, clutch, shaft,
machine) can have one or more points of resonance. These resonances lead to oscillations.
The suppression bandwidths can be used to prevent operation in the resonance frequency
range.
The limit frequencies can be set via p1080[D] and p1082[D]. Further, using connectors
p1085[C] and p1088[C] it is possible to influence these limits in operation.

Minimum speed
Using parameter p1106[0...n], a minimum speed n_min s_src or minimum velocity can be
set, which is wired via BICO.
