Data size
P1.20
Modbus address
P1.21* resonant frequency
P1.22* resonant frequency
This group of parameter displays mechanical resonant frequency. When P1.20 is set to 1,
indicating mechanical resonance frequency detection is valid, the system detects and displays the
frequency at the maximum resonance point.
Note:
 The measurement results are accurate only when the rotation speed reaches 30 r/min at least.
 This function is read only. You can set the notch filter frequency through this group of parameter
to eliminate mechanical resonance.
 The value 5000 indicates no resonance point is found.

Frequency of notch
P1.23
This parameter specifies the frequency of notch filter 1 for suppressing resonance. The notch filter
can simulate the mechanical resonant frequency, thus suppressing the resonant frequency.
The value 5000 indicates the notch filter function is invalid.

Q factor of notch
P1.24
This parameter specifies the quality factor (Q factor for short) of notch filter 1.
Q factor of notch filter = Center frequency of notch filter/Bandwidth of notch filter
Generally, the default value is kept.
