Co: Temperature Input / Temp_Input; Co: Motor Temperature / Mot Temp - Siemens SINAMICS G150 Manual

2 Parameters
2.2 List of parameters
Dependency: The thermal motor utilization is only determined for permanent-magnet synchronous motors when the motor
temperature model 1 (I2t) or 3 is activated.
For motor temperature model 1 (I2t) (p0612.0 = 1), the following applies:
- r0034 = (motor model temperature - 40 K) / (p0605 - 40 K) * 100 %
For motor temperature model 3 (p0612.2 = 1), the following applies:
- r0034 = (motor model temperature - p5397) / (p5398 - p5397) * 100 %
Refer to: p0611, p0612, p0615
Notice: After the drive is switched on, the system starts to determine the motor temperature with an assumed model value.
This means that the value for the motor utilization is only valid after a stabilization time.
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).

B_INF Can be changed: -
Data type: FloatingPoint32
P-Group: Displays, signals
Not for motor type: -
Min
- [°C]
Description: Displays the temperature currently measured at X21 (booksize) or X41 (chassis).
For a BLM with internal Braking Module, a bimetallic sensor must be connected up to monitor the temperature of the
braking resistor. The temperature sensor type is indicated using p0601 and cannot be changed for the existing
internal Braking Module.
Temperature within permissible limit values: r0035 = -50°C
Temperature outside the permissible limit values: r0035 = 250°C
Notice: The function in r0192.11 must be available in order to obtain a correct display.
Note: For r0035 equal to -200.0 °C, the following applies:
- "no sensor" selected in p0601!
For r0035 equal to -300.0 °C, the following applies:
- a KTY84 is selected in p0601 but is not connected!
- the temperature display is not valid (temperature sensor error)!
r0035

- [°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 sensor is connected.
- the thermal model for the induction motor is activated (p0612 bit 1 = 1 and temperature sensor de-activated: 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 de-activated (p0600 = 0 or p0601 = 0).
