4-7-2 Feed-forward Function (Position)
■
• This function shortens positioning time by automatically, in the Servo Driver, adding the position
• Perform feed-forward compensation to increase Servo gain efficiency, thus improving response.
■
Note When not using the feed-forward function, set Pn10A to 0.
■
• Finish adjusting the gain before adjusting the feed-forward.
• Increase the Pn109 (feed-forward amount) setting until positioning time is minimal. At this point, if
• If the overshoot is too large, increase Pn10A (feed-forward command filter) to reduce the it.
• In the Servo Driver, feed forward compensation is applied to position control. This function is used

There is very little effect, however, on systems with sufficiently high position loop gain.
there are no problems with using overshoot, adjustments are complete. A high setting may cause
the machinery to vibrate. With ordinary machinery, set the gain to 80% maximum. (Adjust the gain
while checking the machine response.)
