Control Method Objects
This section explains the objects that set the operations in the one-degree-of-freedom and
two-degree-of-freedom controls.
Sets the velocity feed-forward in the one-degree-of-freedom control.
• Sets the one-degree-of-freedom velocity feed-forward gain.
• The velocity feed-forward can reduce a following error and improve the responsiveness during posi-
tion control.
• Although the following ability is improved by the increase in gain, overshooting may occur in some
cases.
• Selects whether to enable or disable the low-pass filter in the velocity feed-forward.
Description of Set Values
• Sets the low-pass filter cutoff frequency in the one-degree-of-freedom velocity feed-forward filter.
