4.9
Data Analysis Function
This function performs data analysis processing such as fast Fourier transform, digital filter operation, calculation of a cross
point between a wave and a specified value, and calculation of a standard deviation.
This function enables the detection of machining errors by monitoring current wave and the preventive maintenance of
devices by analyzing vibrations.
For data analysis functions and statistical analysis functions, refer to the following manual.
