1...3 PTC
The function is active. The temperature is supervised using one to three PTC
sensors. Analogue output AO1 feeds constant current through the sensor(s).
The resistance of the sensor increases sharply as the motor temperature rises
over the PTC reference temperature (
T
ref
), as does the voltage over the
resistor. The temperature measurement function reads the voltage through
analogue input AI1 and converts it into ohms. The figure below shows typical
PTC sensor resistance values as a function of the motor operating
temperature.

MOT 1 TEMP ALM L
Defines the alarm limit for motor 1 temperature measurement. The alarm
indication is given when the limit is exceeded.

MOT 1 TEMP FLT L
Defines the fault trip limit for motor 1 temperature measurement. The fault
indication is given when the limit is exceeded.

MOT 2 TEMP AI2 SEL Activates the motor 2 temperature measurement function and selects the
sensor type. Two motors can be protected only by using an optional analogue
extension module. Parameter
needs to be activated.
Note:
is activated, the analogue I/O extension is also used for motor 1
temperature measurement (the standard I/O terminals are not in use).
Note:
If an optional analogue I/O extension module RAIO is used for the
temperature measurement and
MOT 1 TEMP AI1 SEL and/or
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.
