Operation
Calculating the Ramp Time
Do not change the camera frame rate abruptly!
The rate of the permissible camera fps change depends on
the beginning frame rate and the acceleration characteristics
of the lens motor. The minimum change time as described
below should not be exceeded!
All values given here are for the fast reaction time setting.
The minimum change time should be doubled if the
reaction time is set to SLOW.
The minimum change time can be calculated using the
following formula:
t Minimum ramp time (in seconds)
V
1
Beginning frame rate for a positive ramp or
ending frame rate for a negative ramp (in fps)
V
2
Ending frame rate for a positive ramp or
beginning frame rate for a negative ramp (in fps)
Beginning Frame Rate Time Ending Frame Rate
