Description: Display and connector output for the motor utilization from motor temperature model 1 (I2t) or 3.
For motor temperature model 1 (I2t) (p0612.0 = 1), the following applies:
For firmware version < 4.7 SP6 or p0612.12 = 0:
- r0034 = (motor model temperature - 40 K) / (p0605 - 40 K) * 100 %
From firmware version 4.7 SP6 and p0612.12 = 1:
- r0034 = (motor model temperature - p0613) / (p0605 - p0613) * 100 %
For motor temperature model 3 (p0612.2 = 1), the following applies:
- r0034 = (motor model temperature - p5397) / (p5398 - p5397) * 100 %
Dependency: The thermal motor utilization is only determined when the motor temperature model 1 (I2t) or 3 is activated.
The following conditions are a prerequisite for additional information.
- a temperature sensor has not been parameterized (p0600, p0601).
- the current corresponds to the stall current (p0318).
- speed n > 1 [rpm].
For firmware version < 4.7 SP6 or p0612.12 = 0, the following applies:
- the temperature model operates with an ambient temperature of 20 °C.
A motor utilization of 100% is displayed (r0034 = 100 %) when the following conditions are permanently fulfilled:
- the ambient temperature is 40 °C (model 1: p0625 = 40 °C, model 3: p0613 = 40 °C).
From firmware version 4.7 SP6 and p0612.12 = 1, the following applies:
- the ambient temperature can be adapted to the conditions using p0613.
Refer to: p0605, p0611, p0612, p0613, p0627, r0632
Refer to: F07011, A07012
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/PT1000 temperature 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).
