6.2.2 Self-adaptive vibration control

P1.19
detection sensitivity
This parameter specifies the sensitivity of the automatic detection on mechanical resonant
frequency. A smaller value of this parameter indicates higher sensitivity to the resonance.

Modbus address
P1.20
detection mode
This parameter specifies the working mode of resonance detection, resonant frequency presumed
by the self-adaptive notch filter, and action after presumption.
If the function of automatically detecting the mechanical resonant frequency is valid (that is, this
parameter is set to 1, 2, or 3), the system automatically collects data to conduct mechanical
resonant frequency analysis and saves results to P1.21 and P1.22. You can set the notch filter
frequency according to the settings of P1.21 and P1.22 to eliminate the mechanical resonance.
Note: You are recommended to disable the function after the gain adjustment is complete.

All parameters associated with the notch filter remain unchanged.
The parameters associated with the third notch filter are updated
according to the self-adaptive result.
The parameters related to the third and fourth notch filters are
updated according to the self-adaptive result.
The mechanical resonant frequency is detected automatically but
the parameters associated with notch filters are not set.
The parameters associated with the four notch filters are restored
to the default values.
The parameters of the third notch filter to are automatically copied to
the first notch filter and then restored to the default values.
The parameters of the fourth notch filter to are automatically copied to
the first notch filter and then restored to the default values.
The parameters of the third and fourth notch filters to are automatically
copied to the first and second notch filters and then restored to the
default values.
