73 AMS 304 i Leuze electronic
9.4.3.11 Module 10: Velocity
Description
Outputs the current velocity with the configured resolution. The unit (metric or inch) is set
in module 1 (position value) and also applies to the velocity. If module 1 is not configured,
the AMS 304
i operates with the default unit (metric).
The sign of the velocity is dependent on the count direction in module 1d.
In the default setting a positive velocity is output when the reflector moves away from the
AMS 304
i . When the reflector moves towards the AMS 304 i , negative velocities are output.
If the "negative" count direction is configured in module 1, the velocity signs are reversed.
Measurement value preparation averages all velocity values calculated during the selected
period to yield a velocity value.
