over the sensor. The temperature measurement function reads the voltage through
the analog input and converts it into degrees Celsius.
It is possible to adjust the motor temperature supervision limits and select how the
drive reacts when overtemperature is detected.
See section Implementing a motor temperature sensor connection on page 83 .
For the wiring of the sensor, see chapter Electrical installation, section AI1 and AI2 as
Pt100, Pt1000, Ni1000, KTY83 and KTY84 sensor inputs (X1) in the drive hardware

.
Temperature monitoring using Pt1000 sensors
1…3 Pt1000 sensors can be connected in series to an analog input and an analog
output.
The analog output feeds a constant excitation current of 0.1 mA through the sensor.
The sensor resistance increases as the motor temperature rises, as does the voltage
over the sensor. The temperature measurement function reads the voltage through
the analog input and converts it into degrees Celsius.
See section Implementing a motor temperature sensor connection on page 83 .
For the wiring of the sensor, see chapter Electrical installation, AI1 and AI2 as Pt100,
Pt1000, Ni1000, KTY83 and KTY84 sensor inputs (X1) in the Hardware manual of the
drive.
Temperature monitoring using Ni1000 sensors
One Ni1000 sensor can be connected to an analog input and an analog output on the
control unit.
The analog output feeds a constant excitation current of 9.1 mA through the sensor.
The sensor resistance increases as the motor temperature rises, as does the voltage
over the sensor. The temperature measurement function reads the voltage through
the analog input and converts it into degrees Celsius.

Temperature monitoring using KTY84 sensors
One KTY84 sensor can be connected to an analog input and an analog output on the
control unit.
The analog output feeds a constant excitation current of 2.0 mA through the sensor.
The sensor resistance increases as the motor temperature rises, as does the voltage
over the sensor. The temperature measurement function reads the voltage through
the analog input and converts it into degrees Celsius.
