Description
KTY84 sensor connected to the analog input selected by
parameter 35.24 Temperature 2 AI source
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
• Select the analog input in parameter 35.24. In case the
input is located on an I/O extension module, use the
selection Other to point at the actual input value

(for example, 14.26 AI1 actual
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.
