Description
Ni1000 sensor connected to the analog input selected by
parameter 35.14 Temperature 1 AI source
output.
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
• In parameter group 13 Standard
selection parameter of the analog output to
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.
Not for ASCL2 and ASCL4 firmware. Will be available for
ASCD2 and ASCD4 firmware later.
PTC is connected to the CMOD-02 multifunction extension
module, which is installed in drive slot 2. See chapter
Optional I/O extension modules, section CMOD-02
multifunction extension module (external 24 V AC/DC and
isolated PTC interface) in the Hardware manual of the drive).
PTC sensor or a normally closed thermistor connected relay
to digital input DI6. The motor is overheated when the digital
input is 0.
Normally open thermistor relay connected to digital input DI6.
The motor is overheated when the digital input is 1.

The unit is selected by parameter
Note: With a PTC sensor, changing the value of this
parameter has no effect on fault generation. When PTC is
over the triggering threshold of the CMOD-02 (see the
Hardware manual), the drive trips on the fault and when PTC
has decreased below recovery threshold of the CMOD-02
(see the Hardware manual), the fault is reset.
