11.4 Resonance suppression
Overvie
w
The resonance suppression functions suppresses mechanical resonance at a frequency higher
than 100 Hz.
The function is achieved by setting the current setpoint lters as bandstop lters. Four current
setpoint lters are available for the converter.

tion of function
Resonance suppres
sion with autotuning
During the autotuning process, resonance suppression is activated by default.
• Resonance suppression with One Button Tuning (p5300 = 1, p5291.1 = 1)
The current setpoint lters are automatically determined and set once with the aid of a noise
signal. Four current setpoint lters can be activated at most after One Button Tuning is
completed.
• Resonance suppression with Real Time Tuning (p5300 = 2, p5302.6 = 1)
Filter 4 is automatically parameterized as a bandstop lter and activated as an adaptive
resonance lter. To use the other three current setpoint lters in this case, you must manually
congure their settings.
When there is no resonance in the machine, Siemens recommends that the resonance
suppression function is deactivated (p5302.6 = 0) in Real Time Tuning to get a high dynamic
performance.
