* Waveform during stopped in C axis (Reference)
* Waveform when executing cutting feed with G01 F20 (Reference)
[2] When satisfactory accuracy is not secured, increase SP008 (VGN2) by 10 increments and adjust so that the
accuracy level meets the standard. Note that the maximum setting value is 150 x [inertia ratio].
(3) Setting the notch filter
During spindle C axis operation, there are times where motor is rotated while brake is applied, resulting in
resonance occurred. In this case, measure resonance frequency from q axis current command waveform and set
the value to SP038 (notch filter 1). Also, depending on the set frequency, filter depth must be set to SP034. When
notch filter is set, perform acceleration/deceleration operation at the maximum speed and confirm that no abnormal
oscillation or noise is found.
Notch filter's set frequency and standard depth setting
Setting example: When there are 16 wavelengths within 0.02 sec.
Set 800 to SP038 and XXX0 to SP034. Measure position droop and current command at this time, and adjust notch
filter's frequency and depth so that the position droop is within standard range.
