Siemens SINAMICS G120X - CO: Motor Temperature; Mot Temp; CO: Power Unit Overload I2 T; PM Overload I2 T; CO: Power Unit Temperatures; PM Temperatures

Note
Smoothing time constant = 100 ms
The signal is not suitable as a process quantity and may only be used as a display quantity.
For r0034 = -200.0 %, the following applies:
The value is invalid (e.g. the motor temperature model is not activated or has been incorrectly parameterized).
r0035 CO: Motor temperature / Mot temp
Access level: 2 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: p2006 Dynamic index: -
Unit group: 21_1 Unit selection: p0505 Function diagram: 8016, 8017
Min:
- [°C]
Max:
- [°C]
Factory setting:
- [°C]
Description: Display and connector output for 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/PT1000 temperature sensor is connected.
- the thermal model for the induction motor is activated (p0612 bit 1 = 1 and temperature sensor deactivated: p0600 =
0 or 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.
- the temperature sensor of the synchronous motor is deactivated (p0600 = 0 or p0601 = 0).
r0036 CO: Power unit overload I2t / PM overload I2t
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: PERCENT Dynamic index: -
Unit group: - Unit selection: - Function diagram: 8021
Min:

Max:
- [%]
Factory setting:
- [%]
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.
