296 Parameters
Defines the warning limit for temperature monitoring function
1. When measured temperature 1 exceeds this limit, a
warning (
) is generated.
The unit is selected by parameter
Note:
With a PTC sensor, the unit is ohms.
110 °C,
230 °F or
4000 ohm
-60 … 1000 °C,
-76 … 1832 °F or
0…5000 ohm
Warning limit for temperature monitoring function 1.
1 = 1 unit
Specifies the analog input when the setting of
requires measurement through an
analog input.
Note:
If the input is located on an I/O extension module, use
to point to the AI actual value in group 14,
Not selected
None.
0
AI1 actual value
Analog input AI1 on the control unit.
1
AI2 actual value
Analog input AI2 on the control unit.
2
). -
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.
Disabled
None. Temperature monitoring function 2 is disabled.
0
Estimated
temperature
Estimated motor temperature (see parameter
).
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 selected by
parameter
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
”.
• Select the analog input in parameter
. In case the
input is located on an I/O extension module, use the
selection
to point at the actual input value parameter
(for example,
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.
