Страница: 325 / 664

Parameters 325
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 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 35.14 . In case the
input is located on an I/O extension module, use the
selection
Other 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.

1 × Pt100 analog
I/O Pt100 sensor connected to a standard analog input selected
by parameter
35.14 Temperature 1 AI source and an analog
output. The input and output can be on the drive control unit
or on an extension module.
The required settings are the same as with selection
KTY84
analog I/O , except that the source selection parameter of the
analog output must be set to Force Pt100 excitation .

2 × Pt100 analog
I/O As selection 1 × Pt100 analog I/O , but with two sensors
connected in series. Using multiple sensors improves
measurement accuracy significantly.
6
3 × Pt100 analog
I/O As selection 1 × Pt100 analog I/O , but with three sensors
connected in series. Using multiple sensors improves
measurement accuracy significantly.
7
PTC DI6 PTC sensor connected to digital input DI6 (see the
connection diagram on page
116 ).
Note: Either 0 ohm (normal temperature) or 4000 ohm
(excessive temperature) will be shown by 35.02 Measured
temperature 1 . By default, an excessive temperature will
generate a warning as per parameter 35.13 Temperature 1
warning limit . If you want a fault instead, set 35.12
Temperature 1 fault limit to 4000 ohm.
8
PTC analog I/O PTC sensor connected to a standard analog input selected by
parameter
35.14 Temperature 1 AI source and an analog
output. The input and output can be on the drive control unit
or on an extension module.
The required settings are the same as with selection
KTY84
analog I/O , except that the source selection parameter of the
analog output must be set to Force PTC excitation .
