Temperature monitoring using KTY83 sensors
One KTY83 sensor can be connected to an analog input and an analog output on the
control unit.
The analog output feeds a constant excitation current of 1.0 mA through the sensor.
The sensor resistance increases as the motor temperature rises, as does the voltage
over the sensor. The temperature measurement function reads the voltage through
the analog input and converts it into degrees Celsius.
The figure and table below show typical KTY83 sensor resistance values as a
function of the motor operating temperature.
It is possible to adjust the motor temperature supervision limits and select how the
drive reacts when overtemperature is detected.
