2KTY84 sensor connected to the analog input selected
by parameter 35.14 Temperature 1 AI source and an
analog output. The input and output can be on the drive
control unit or on an extension module.
The following settings are required:
• Set the hardware jumper or switch related to the
analog input to U (voltage). Any change must be
validated by a control unit reboot.
• Set the unit selection parameter of the input to
volt.
• Set the source selection parameter of the analog
output to “Force KTY84 excitation”.
• Select the analog input in parameter 35.14. In case
the input is located on an I/O extension module,
use selection Other (see Terms and
abbreviations (page 20)) to point at the actual
input value parameter (for example, 14.26 AI1
actual value).
The analog output feeds a constant current through
the sensor. As the resistance of the sensor changes
along with its temperature, the voltage over the sensor
changes. The voltage is read by the analog input and
converted into degrees.

5Pt100 sensor connected to a standard analog input
selected by parameter 35.14 Temperature 1 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.
