Selection No.
Disabled / uint16 Selects the source from which measured temperature
2 is read.
For wiring examples, see the hardware manual of the
drive.
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. Temperature 2
source 35.21
0 None. Temperature monitoring function 2 is disabled. Disabled
1 Estimated motor temperature (see parameter 35.1
Motor 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
temperature .

temperature
2 KTY84 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 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.
