SPINFamily tool for ihm03a1 - application crash when set motor >2 Ohms at menu

Hi @dungeonlords789 ,

Thanks for the info provided. I think I understood what is causing the error.

The parameters you set (Lm = 5mH, Rm = 8 Ohm) correspond to a value of INT_SPEED about equal to 1016 step/s that is higher than the maximum allowed value

of INT_SPEED register (976.5 step/s).

This is the reason why an exception is raised.

I know it could be a little bit confusing and the GUI should provide a clearer explanatory message.

However, I can suggest how to run the wizard and configure the POWERSTEP01 to run your motor.

In the wizard you have to set Lm = 5.25 mH or higher.

This is just to go on, we will change it to the correct value later.

The other parameters can be left unchanged.

Go on with the different configurations of the wizard, till it is done and you can write the configuration registers.

Now you can open the "BEMF compensation" window as shown here:

Set here the correct parameters, so Lm = 5mH, Rm = 8 Ohm, together with the other parameters.

Click the “evaluate button�?: you will still get a warning but you can write the configuration registers for compensation, clicking the “write button.

Now the motor should run properly.

You can even fine tune the slopes (ST_SLP, FN_SLP_ACC /FN_SLP_DEC) in order to keep the phase current as much as constant in the entire speed range of your application.

Try to follow these suggestion and let me know if the motor runs as expected.

Hi @dungeonlords789 ,

I need some more information to understand and help you to fix this unexpected problem.

When you set the motor > 2 ohm, are you referring to the “BEMF compensation�? window ?

If so, I suppose you want to run your motor in voltage mode.

Which are the other parameters you set in this window ?

What do you mean exactly with “application crash�? ? Does the window just close or you get some kind of error message ?

Does the application crashes when you write the BEMF compensation registers ?

I use Wizard -> Voltage mode. Look at picture.

@Dario CUCCHI did you plan fix SPINFamily tool for ihm03a1 or provide source codes of aplication? This is some extra suggestions from me.

SPINFamily crash when set motor >2 Ohms at menu, see above
It is cool idea generate settings file in C format. But is is bette to use typedef union powerstep01_Init_u not define. See powerstep01 example:

It will be more userfriendly to allow use Wizard of SPINFamily without connection to Nucleo board. I create custom board and I want generate settings to it.

Dario CUCCHI · ‎2020-11-05

Thanks @dungeonlords789 for your suggestions: I will forward them and ask to introduce these modification in the software.

Anyway, the source code of the software cannot be distributed.

Regarding the use of the GUI without the board connected:

If I well understood, you need to use the BEMF compensation window as a calculator to get the compensation coefficients.

You can try to open the GUI and select the tab “PCC0092 & EVAL�?.

In this case you can open the main screen , select the “BEMF compensation�? button and open the window without any board connected.

Then, you can set all the parameters and press the evaluate button to get graphs and compensation coefficients.

Hope this can help you.

@Dario CUCCHI any news about SPINFamily tool ihm03a1 update?

Dario CUCCHI · ‎2021-01-11

No news for the moment.

Dario CUCCHI · ‎2021-02-09

Hi @dungeonlords789

this is just to give you an update on the SPINFamily GUI.

Unfortunately the new GUI version to introduce the modifications discussed above was put on hold.

Meaning that a new version of this GUI will not be available soon…

dungeonlords789 · ‎2021-02-12

I suggest make SPINFamily opensource.
