Note 1. The servo-system loop gain will rise in response to a higher rigidity setting, shortening posi-
tioning time. If the setting is too large, however, the machinery may vibrate, so make the set-
ting small.
Note 2. When the rigidity is set, the user parameters in the above table will change automatically.
