Description
Selects the source from which measured temperature 1 is
read.
Usually this source is from a sensor connected to the motor
controlled by the drive, but it could be used to measure and
monitor a temperature from other parts of the process as long
as a suitable sensor is used as per the selection list.
None. Temperature monitoring function 1 is disabled.
Estimated motor temperature (see parameter
estimated temperature).
The temperature is estimated from an internal drive
calculation. It is important to set up the ambient temperature
of the motor in 35.50 Motor ambient
Pt100 sensor connected to a standard analog input selected
by parameter 35.14 Temperature 1 AI source
output.
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 appropriate analog input unit selection parameter
in group 12 Standard AI
• In parameter group 13 Standard
selection parameter of the analog output to
excitation.
The analog output feeds a constant current through the
sensor. As the resistance of the sensor increases along with
its temperature, the voltage over the sensor increases. The
voltage is read by the analog input and converted into
degrees.
As selection 1 × Pt100 analog

measurement accuracy significantly.

PTC sensor is connected to DI6.
Note: With a PTC sensor, the value shown is not a valid
measurement. Either 0 ohm (normal temperature) or the

The temperature is taken from the source selected by

source is assumed to be degrees Celsius.
PTC is connected to the CMOD-02 multifunction extension
module, which is installed in drive slot 2. See chapter
