9.2.6 Object 2008h: Speed Integration Time
Defines the integration time in [ms] for "Object 2005h: Speed unit", see chapter 9.2.3 on
page 171.
The parameter serves to calculate the velocity, which is output via the cyclic process
input data. The velocity is specified in [ (Steps/Integration Time) * Factor ]. High
integration times enable high-resolution measurements at low speeds. Low integration
times show velocity changes more quickly and are suitable for high speeds and high
dynamics.

Example
Given:
- Programmed resolution = 8192 steps per revolution
- Velocity = 4800 revolutions per minute
- Integration time t
- Factor = 1
Find:
- Output value in (Steps/Integration Time) * Factor
Number of steps / s =
Number of steps / t
(Steps/integration time) * factor = 32768 steps / 50 ms
