Compensation Dead Time Voltages; Temperature Adaption Motor Resistances; Temperature Adaption Slip Frequency - Baumuller b maXX BM3000 Operating Manual

Description of the Software Modules and Parameters
If the motor operates in the high speed range then due to the high loads the motor reach-
es the non-linear range of the characteristic. The Lq inductance increases the saturation.
The Kp gain of the current controller dependent on the torque current is adapted directly.

4.7.7.8 Temperature adaption motor resistances

The temperature influence in the stator resistance can be modeled as follows:
with:
The temperature adaption applies to the following:
The adaption is made automatically if the motor temperature monitoring is activated.

4.7.7.9 Temperature adaption slip frequency

At asynchronous motors with an encoder the output frequency are relatively to the rotor
frequency is determined by the slip frequency specification, f
portional to the torque current set value. It is inversely proportional to the magnetic flux
set value. It is calculated by the slip frequency at the motor nominal torque current and
the nominal flux, F
