Parameters 121
35.03 Measured
temperature 2 Shows temperature received through the source defined by
parameter
35.21 Temperature 2 source . The unit is selected
by parameter 96.16 Unit selection .
Note: With a PTC sensor, the value shown is not a valid
measurement. Either 0 ohm (normal temperature) or the
value of parameter
35.22 Temperature 2 fault limit (excessive
temperature) is shown.
This parameter is read-only.
0
-60…5000 °C or
-76…9032 °F Measured temperature 2. 1 = 1 unit
35.05 Motor overload
level Motor overload level as a percentage of the fault limit. 0.0
0.0...300.0 % Motor overload level 1 = 1unit
35.11 Temperature 1
source 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. Estimated
temperature
Disabled None. Temperature monitoring function 1 is disabled. 0
Estimated
temperature Estimated motor temperature (see parameter 35.01 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 .

KTY84 analog I/O KTY84 sensor connected to the analog input selected by
parameter
35.14 Temperature 1 AI source and an analog
output. The analog input can be from the standard I/O or from
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 appropriate analog input unit selection parameter
in group 12 Standard AI to V (volt).
• In parameter group 13 Standard AO , set the source
selection parameter of the analog output to Temp sensor 1
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.
