The BCD code composed of two bits determines
the filter to be turned on
。
Bit4
：
1 :Indicates FFT analysis using actual current
，
0 :Indicates that the target current is used for analysis
Bit5
：
1: Indicates use actual speed for FFT analysis
，
0:
Indicates do not use actual speed for FFT analysis
Bit.7：1 Indicates that the FFT function is turned on, it will
automatically become 0 after the analysis is completed, and
it can only be turned on in the enabled state.

(1) Single-point notch filter
When the notch filter control (60F9.04) is set to 0, it indicates to close the notch filter control; when set to1, it indicates to open a
single notch filter, and the frequency of the filter is set by the notch filter (60F9.03) .

Instruction
Process
Limit output current of drive
Enter D2.14 of F002 through the panel to adjust the MAX output current RMS or adjust the target
current limit through the basic operation interface of the servo software.
Use the oscilloscope to
collect the current waveform
in the resonance region. Note
that when collecting the
current with the oscilloscope,
the sampling period should be
set as small as possible,
otherwise the resonance
waveform may not be
collected.
Observe the resonant
frequency with an
oscilloscope and calculate the
notch filter setting value
based on the frequency
The resonant frequency in the figure is 200Hz, the notch filter control is set to 1, and the notch
filter is set to 200Hz
