SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 11/2009
Description:
Displays the actual temperature in the motor.
Note:
For r0035 not equal to -200.0 °C, the following applies:
- this temperature display is valid.
- a KTY sensor is connected.
- for induction motors, the thermal motor model is activated (p0601 = 0).
For r0035 equal to -200.0 °C, the following applies:
- this temperature display is not valid (temperature sensor error).
- A PTC sensor or bimetallic NC contact is connected.
- for synchronous motors, the thermal motor model is activated (p0601 = 0).
Description:
Displays the power unit overload determined using the I2t calculation.
A current reference value is defined for the I2t monitoring of the power unit. It represents the current that can be
conducted by the power unit without any influence of the switching losses (e.g. the continuously permissible current
of the capacitors, inductances, busbars, etc.).
If the I2t reference current of the power unit is not exceeded, then an overload (0 %) is not displayed.
In the other case, the degree of thermal overload is calculated, whereby 100% results in a trip.
Dependency:
Refer to: p0290, p0294
Refer to: F30005
Description:
Displays the temperatures in the power unit.
