Parameters
Only the parameters that are relevant for the frequency meter are explained below. These are
part of the parameters of the electronic module 8 DI NAMUR:
Table 4-17 Parameters for the frequency meter
Parameters Setting Description
Encoder type frequency
inputs
• Channel disabled
• NAMUR sensor
• Single contact unconnec‐
ted
For channel 0 or 1, select the sensor for the
respective frequency meter.
Measuring window
(TOR)
• 50 ms
• 200 ms
• 1 s
Select the required measuring window for
channel 0 or 1.
To achieve the highest possible accuracy in
frequency measurement, observe the follow‐
ing rules:
• High frequencies (>4 kHz): Set low meas‐
uring window (50 ms)
• Variable/ medium frequencies: Set mid‐
dle measuring window (200 ms)
• Low frequencies (<1 kHz): Set high meas‐
uring window (1 s)
