Note: If an optional analogue I/O extension module RAIO is used for the
temperature measurement and
MOT 2 TEMP AI2 SEL are set to 1xPT100, analogue extension module input
signal range must be set to 0 ... 2 V (instead of 0 ... 10 V) with DIP switches.
The function is inactive.
The function is active. The temperature is measured with one Pt 100 sensor.
Analogue output AO1 feeds constant current 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
analogue input AI1 and converts it to degrees centigrade.
The function is active. Temperature is measured using two Pt 100 sensors.
See selection 1xPT100.
The function is active. Temperature is measured using three Pt 100 sensors.
See selection 1xPT100.
