Selection No.
5 Pt100 sensor connected to a standard analog input
selected by parameter
35.24 Temperature 2 AI source
and an analog output. The input and output can be on
the drive control unit or on an extension module.
The required settings are the same as with selection
KTY84 analog I/O , except that the source selection
parameter of the analog output must be set to Force
Pt100 excitation .
1 x Pt100 analog I/O
6 As selection 1 x Pt100 analog I/O , but with two sensors
connected in series. Using multiple sensors improves
measurement accuracy significantly.
2 x Pt100 analog I/O
7 As selection 1 x Pt100 analog I/O , but with three
sensors connected in series. Using multiple sensors
improves measurement accuracy significantly.
3 x Pt100 analog I/O
8 PTC sensor connected to digital input DI6 (see the
connection diagram on page
128 ).
Note: Either 0 ohm (normal temperature) or 4000 ohm
(excessive temperature) will be shown by
35.3 Measured
temperature 2 . By default, an excessive temperature
will generate a warning as per parameter 35.23
Temperature 2 warning limit . If you want a fault instead,
set 35.22 Temperature 2 fault limit to 4000 ohm.

how the selection value should be interpreted. PTC DI6
20 PTC sensor connected to a standard analog input
selected by parameter
35.24 Temperature 2 AI source
and an analog output. The input and output can be on
the drive control unit or on an extension module.
The required settings are the same as with selection
KTY84 analog I/O , except that the source selection
parameter of the analog output must be set to Force
Pt100 excitation .

11 The temperature is taken from the source selected by
parameter
35.24 Temperature 2 AI source . The value of
the source is assumed to be in the unit of temperature
specified by
96.16 Unit selection .

13 Pt1000 sensor connected to a standard analog input
selected by parameter
35.24 Temperature 2 AI source
and an analog output. The input and output can be on
the drive control unit or on an extension module.
The required settings are the same as with selection
KTY84 analog I/O , except that the source selection
parameter of the analog output must be set to Force
