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 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

KTY84 analog
I/O KTY84 sensor connected to the analog input

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.
