The filter is a moving filter. The parameter PB-00 is a low-pass filter. The difference is that the smoothing effect
occurs at the beginning and end of the step command for the moving filter. On the other hand, the smoothing
effect only occurs at the end of the step command for the low-pass filter.
Recommendation: If the speed loop receives the command from the upper computer to form the control of the
position loop, the low-pass filter can be used. For simple speed control, the moving filter can be used for better
smoothing effects.

This indicates the value for friction compensation. (As for the percentage of the rated torque, set 0 to turn off the
function for friction compensation and set 1 to turn it on.)
