2.2 List of parameters
Description: Displays the smoothed actual value of the active power.
Dependency: Refer to: r0082
Notice: This smoothed signal is not suitable for diagnostics or evaluation of dynamic operations. In this case, the
unsmoothed value should be used.
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 thermal 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: 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.
- 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).
