Note: Smoothing time constant = 100 ms
The signal is not suitable as a process quantity and may only be used as a display quantity.
The torque utilization is available smoothed (r0033) and unsmoothed (r0081).
For M_set total (r0079) > 0, the following applies:
- Required torque = M_set total
- Actual torque limit = M_max upper effective (r1538)
For M_set total (r0079) <= 0, the following applies:
- Required torque = - M_set total
- Actual torque limit = - M_max lower effective (r1539)
For the actual torque limit = 0, the following applies: r0033 = 100 %
For the actual torque limit < 0, the following applies: r0033 = 0 %
r0034 CO: Motor utilization / Motor utilization
Access level: 2
Can be changed: -
Units group: -

- [%]
Description: Displays the motor utilization from motor temperature model 1 (I2t) or 3.
Dependency: The 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).
r0035 CO: Motor temperature / Mot temp
Access level: 2
Can be changed: -
Units group: 21_1
Min
- [°C]
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).
