Hello @backb0ne
We will try your configuration in our lab and share further our findings.
Please consider that the profiler project aims only to profile your motor. Once your motor is profiled, the recommended way of working is to generate a new project with your profiled motor from the motor library without the profiling option.

Hi @cedric H
Thanks for your response and for taking the time to test it on your side.
To bring a bit more precision, attached is the project. I am using a custom board adapter to change couple signal allocation.
I am guessing it is not link, but we never know: I have installed the patch attached in the following discussion to make the Hall profiling working.
Don't hesitate if you want me to do any test.
Thanks.

Hello backb0ne,
I have tested your configuration, and I managed to profile a motor with it. Could you describe more precisely the issue you are facing while profiling ? Also know that motor parameters do not need to be put via workbench, as you have to input them in MotorProfiler afterwards.
In your first post you mentioned that the initial profiling worked, what do you want to do after getting your motor's information ?
Also, the hall profiling patch should not have any impact since you are only using sensorless although it's always nice to have it.

Hi @Gael A
I wanted to profile another motor, and managed to successfully do the first one, but not the second one.
I may have found the problem. The system doesn't like when both Open Loop and Motor Profiler are selected. It works fine when only one of them is selected. I will do more test to confirm.
I have an additional question regarding the motor profiler. It is supposed to be independant on the motor configured. However, it seems like the errors faults raised during the profiling are linked to the project configuration: I had to increase the max num error before fault for speed feedback error. Same for maximum voltage.
What are the other parameters take into account for the motor profiling ? Is the Start-up profile take into account ?
Thanks

Hello backb0ne,
The Motor Profiler was designed to be used as a standalone, it is not meant to be working with most features such as the Open Loop mode, this is probably why you have experienced issues, as you were saying indeed. Please refrain from enabling any feature when using the Motor Profiler.
However, it can be useful to modify a few options depending on your configuration. This includes Voltage, Current and of course Pole Pair number. All of which can be modified afterwards in the MotorProfiler tool, there is no need to do it via Workbench.
The PWM frequency can also be modified, for low inductances motors for example.
