3:
3 x PT100
Dependency:
When enabled(p29700>0):
1. One analog input and output should be used to connect the sensor, the connected analog input should be set as
0-10V voltage input(p756[x]=0), and the analog output should be set as 0-20mA current output(p776[x]=0);
2. The measure sensor voltage should connect to the sensor voltage input(p29701=r755.x)and the sensor exciting
current value should connect to analog output source(p771[x]=r29706.x).
Note
The temperature sensor is connected at CU AIx and AOx terminals.
When the measurement is enabled(p29700>0), the set value of p601 is not impact on the motor temperature sensor
selection.
If p29700=0, the motor temperature sensor can be selected by p601.

CI: Temperature sensor voltage input source / TempSen V_src
Access level: 2
Calculated: -
Data type: Unsigned32 /
FloatingPoint32
Can be changed: T, U
Scaling: PERCENT

Description:
Sets the signal source for temperature sensor voltage.
Note
The value may be the measured value of the analog input(e.g. r755[x]), which is the AI channel of the sensor connected.

Min:
0.00 [ohm]
Max:

Factory setting:
0.00 [ohm]
Description:
Sets the equivalent wire resistance for temperature sensor.
If the wire resistance can't be ignored for the temperature accuracy, that should be measured or calculated and set via
p29704.
Note
The value may be measured by short-circuit the sensor conductor close to the sensor, set p29704=0, then that can be
read via r29707.
The parameter is not influenced by setting the factory setting.

Note
PT100: Valid temperature range -48 ... 248 degree.
r29705=20 degree is displayed when the sensor type is not selected(p29700 = 0).
