6-3) Adjustment Requiring High - FujiFilm RYB500S3-VBC User Manual

6-3) Adjustment requiring high speed response
Use this method to obtain quicker response than that obtained after adjustment specified in section 6-2
"Application adjustment." (However, do not use the method described here if "adjustment of large
inertia" has been made.)
While measuring the operation time and output timing of the positioning end signal by using historical
trace of the PC loader, make adjustment as follows.
Note 1: Adjust the gain so as not to generate mechanical vibration or torque fluctuation.
Note 2: If mechanical rigidity is poor, gradually increase the S-curve filter (parameter #43) to
suppress vibration.
