Settings:
● Analog output AO and analog input AI:
p0776[0] = 0: AO is current output 0 mA … 20 mA, corresponding to the factory setting 0 %
… 100 %
p0756[x] = 0: AI x is voltage input 0 V … 10 V, corresponding to the factory setting 0 % …
100 %. Also set the associated switch on the converter to "U".
p29701 = r0755[x]. x is the number of the analog input where the Pt100 is connected.
p771[0] = r29706.
● Temperature monitoring: The converter evaluates the motor temperature in the range from
-48 °C ... +248 °C.
– Number of Pt100 connected in series: p29700
– Overtemperature alarm (A07910):
- motor temperature > p0604 and p0610 = 0
– Overtemperature fault (F07011):
The converter responds with a fault in the following cases:
- motor temperature > p0605
- motor temperature > p0604 and p0610 > 0
● The converter does not monitor the sensor.
