4.31.7.8.3 Configuration of the A/D converter
4.31.7.8.3.1 Setting the conversion rate
Name:
InputFilter
This register can be used to set the conversion rate for the Analog/Digital converter.
Data type Value
UINT 5 to 1023
Information:
The lower the conversion interval is set, the more precisely the value can be converted.
However, this also increases the I/O update time.
4.31.7.8.3.2 A/D converter operating mode
Name:
ModeADC
This register can be used to set the operating mode for the Analog/Digital converter.
The individual options allow faster digitalization of the analog values, but this also reduces the precision of the
measured values. The default value is 0.
Data type Value
UINT See bit structure
Bit structure:
Bit Name Value Information
0 Alternating amplification of the analog value 0 Chopper mode
1 Chopper mode off
0 SINC4 1 Order of the SINC filter
1 SINC3
2 - 15 Reserved - -
The following rules apply:
ConversionTime(SINC3) = ConversionTime(SINC4) - 1 x ConversionCycle
ConversionTime(without Chop) = 0.5 x ConversionTime(Chop)
