SINAMICS G120 CU230P-2 Control Units List Manual (LH9), 01/2013
Note: Power delivered at the motor shaft.
The active power is available smoothed (r0032 with 100 ms) and unsmoothed (r0082).
Description: Displays the motor utilization from motor temperature model 1 (I2t).
Dependency: The motor utilization is only determined for permanent-magnet synchronous motors when the motor temperature
model 1 (I2t) is activated.
For motor temperature model 1 (I2t) (p0612.0 = 1), the following applies:
- r0034 = (motor model temperature - 40 K) / (p0605 - 40 K) * 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).
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
