2KTY84 sensor connected to the 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 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 35.24. In case
the input is located on an I/O extension module, use
the selection Other (see Terms and
abbreviations (page 17)) 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 35.24 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.

8PTC sensor connected to digital input DI6 (see the
connection diagram on page 90).
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.
