1) VC - Optimized tuning for a wide range of applications with emphasis on processing speed.
FV - Optimized tuning for the best combination of high dynamic performance and high speed.
2) Calculation of the speed in the working field: Focal length F-Theta lens × speed.
Example: Deflection unit with F-Theta lens f = 254 mm, speed 30 rad/s
=> 254/1000 × 30 = 7.6 m/s.
3) Calculation of acceleration time approx. 1.8 × tracking error.
4) Calculation of acceleration time approx. 2.0 × tracking error.
5) Controlled to 1/5,000 of full scale.
