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 tun ing mode (parameter No.PB01) "manual mode", set up the
machine resonance suppression filter 1 becom es 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 notc h frequency is
set at the point where vibration is minimal.
A deeper notch has a higher effect on machine resonance suppression b ut
increases a phase delay and may increase vibration.
A deeper notch has a higher effect on machine resonance suppression b ut
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 n otch frequency
and depth to be determined.
