8.4.2.2.2 Velocity factor

Indicates the factor value for the Velocity format parameter, see page 151.
Lower limit 1
Upper limit 1000
Default
1

8.4.2.2.3 Velocity integration time

Indicates the integration time in [ms] for the Velocity format parameter, see page 151.
The parameter serves to calculate the speed, which is output via the cyclic process data. The speed is
specified in steps/integration time. High integration times enable high-resolution measurements at low
speeds. Low integration times show speed changes more quickly and are suitable for high speeds and
high dynamics.
Lower limit 1 ms
Upper limit 1000 ms
Default
32 ms
Example
Given:
- Programmed resolution = 8192 steps per revolution
- Speed = 4800 revolutions per minute
- Integration time t = 50 ms = 0.05 s
i
Find:
- Output value in Steps/integration time
Number of steps / s =
Number of steps / t =
i
Steps/integration time = 32768 steps / 50 ms
