Parameter
Description
Range/Values
Speed resolution
The parameter defines the resolu-
tion of the speed value. It affects
only the fieldbus output.
1 mm/s
10 mm/s
100 mm/s
or
Free resolution
Averaging
The parameter specifies the aver-
aging time of the calculated speed
values in steps.
Steps:
1 to 32 ms

Time behavior
The BPS of the 300i series operate with a scanning rate of 1000 scans per second. A measurement value
is ascertained every 1 ms.
The following parameters are relevant for the time behavior of the position and speed measurement:
Parameter
Description
Range/Values
Integration depth
The integration depth affects the
measurement of position and
speed. The
integration depth
pa-
rameter specifies the number of
sequential measurements that the
BPS uses for position determina-
tion.
The integration results in smooth-
ing of the output measurement
value.
With the BPS 300i, an
integration
depth
of 8 yields a response time
of 8 ms.
Factory setting:
8
Update rate
The update rate (50 µs to 2 ms) of
the measurement values at the
SSI interface can be configured
via the webConfig tool; see chap-
ter 9.3.4 "CONFIGURATION func-
tion".
Factory setting:
2 ms
Error delay time
Errors that occur are suppressed
for the configured time.
If no valid position or speed value
can be ascertained in the config-
ured
error delay time
, the last
valid value is always output.
If the error persists after the
error
delay time
elapses, the value of
the
Position/Speed value in case
of error
parameter is then output
(standard).
Factory setting:
50 ms

WebConfig tool
The webConfig configuration tool offers a graphical user interface for the display of process data, configu-
ration and diagnosis of the BPS via a PC; see chapter 9 "Starting up the device – webConfig tool".
