(3) If you keep the setting of X as 1, the known resonance suppression points will not be
cleared, but they are not written to EEPROM yet. They are written to EEPROM when the
servo determines it is stable.
2: auto resonance suppression mode 2; when the servo determines it is stable*
the known resonance suppression points to EEPROM (non-volatile memory for parameters). In
this mode, the searching cycle continues until the 5 sets of resonance suppression parameters
are set, and then the auto resonance suppression function is disabled (X = 0).

Note:
1. If you switch the setting of X from 0 to 1 or 2, the unfixed Notch filter is automatically cleared, the
frequency is set to 1,000 Hz, and the suppression level is set to 0 dB.
2. The servo determines it is stable when the following conditions are met: resonances have been
suppressed, no other interference that affects the operation is found, and the motor speed is maintained
at above 10 rpm for 3 minutes.

Y: fixed resonance suppression parameter
In auto resonance suppression mode, you can set the resonance suppression parameters
manually by setting P2.047.Y.

If you cycle power on the servo drive, the resonance suppression points that are not yet
stored in EEPROM are lost and will not be saved. The resonance suppression points
that have been stored in EEPROM will not be affected.
If you switch the setting of X from 2 to 0, the known resonance suppression points will be
stored to EEPROM.
If you keep the setting of X as 2, the known resonance suppression points will not be
cleared, but they are not written to EEPROM yet. They are written to EEPROM when the
servo determines it is stable.
