Software-Reset will be
executed
1) in the continuous mode the sensor is sending continuous angle values, in the polling mode the sensor is sending one answer after
an instruction
2) only possible at polling mode.
3) for activating a reset or power fail restart is necessary
4) for Code transmission rate see
5) Table 1 <Code transmission rate>
6) for Code baud rate see Erreur ! Source du renvoi introuvable.
Attention! A reset of the baud rate to a default value is not possible. If the user forgets the adjusted baud rate, the new value must
be detected by testing.
7) this instruction is only effectual at sensors with switch output,
8) <switch angle>: three digits from “001” until “300” for the angle in tenths of a degree, max working range of the sensor. Default value
is 025 == 2,5°
9) <hysterese>: two digits from “01” until “99” for the stitching hysterese in tenths of a degree, max working range of the sensor, Default
value is 01 = 0,1°
10) Formulas for Filter :
- Moving Average Filter „M1“, „mm“ (possible values mm = 02 to 40, with mm = 00 is moving average filter deactivated): Output
value = Average over last mm values.
- Exponential Filter „M2“, „tt“ (first order low pass filter, possible values tt = 02 to 40, with tt = 00 is exponential filter deactivated):
Output value = ( old output value * (tt-1) / tt ) + (value / tt )
