Electrical Tuning: Temporal Design


In previous step a tuning in a frequency domain was performed, in this wizard you are going to make it in time domain. You will see how the bandwidth affects your system (control loop+plant) in real time.

This page is not available if trapezoidal commutation is selected.

Control widget

This widget has several subparts for this wizard:

  • Buttons for Tuning and Fault Reset enabling.

  • Control loop parameters

  • Current and voltage limits.


You can use this wizard to verify visually that the tuning is good.

In order to make a tuning in this wizard, click on the Enable button of the Tune in the Control widget.

You notice both charts start to show some information:

  • Chart above shows the current direct, the actual value (blue) and the demand (red).

  • Chart below shows the voltage direct (green).

Notice the current demand is set in the Signal Generator widget.

In addition, you can see the dot next to “Axis 1” is changed from yellow to green. Green color means the motor is enabled, yellow means the motor is disabled but active, and red means the drive is in fault state.

Control loop

On control widget you have 4 registers that you can change:

  • Current direct loop Kp.

  • Current direct loop Ki.

  • Current quadrature loop Kp.

  • Current quadrature loop Ki.

Both proportional parameters will be forced to have the same value, and the same with respect to quadrature parameters.


You can limit the maximum current loop amplitude as well as minimum and maximum voltage loop.

In the image below you can see an example about how these parameters can effect for your system (loop+plant)
