10. SPECIAL ADJUSTMENT FUNCTIONS
(2) Parameters
(a) Machine resonance suppression filter 1 (parameter No.PB13, PB14)
Set the notch frequency, notch depth and notch width of the machine resonance suppression filter 1
(parameter No.PB13, PB14)
When you have made adaptive filter tuning mode (parameter No.PB01) "manual mode", set up the
machine resonance suppression filter 1 becomes effective.
POINT
The machine resonance suppression filter is a delay factor for the servo
system. Hence, vibration may increase if you set a wrong resonance
frequency or a too deep notch.
If the frequency of machine resonance is unknown, decrease the notch
frequency from higher to lower ones in order. The optimum notch frequency is
set at the point where vibration is minimal.
A deeper notch has a higher effect on machine resonance suppression but
increases a phase delay and may increase vibration.
A deeper notch has a higher effect on machine resonance suppression but
increases a phase delay and may increase vibration.
The machine characteristic can be grasped beforehand by the machine
analyzer on the MR Configurator. This allows the required notch frequency
and depth to be determined.
