STEVAL-PTOOL4A : Error MC_DP_FAULT and Motor Profiler Connection Issue

[JulesC]

Hello,

I am attempting to run a Brushless DC-Flat motor using the STEVAL-PTOOL4A board. However, the system fails right after entering the RUN state, returning an ERROR MC_DP_FAULT (via MC_GetOccurredFaultsMotor1).

To resolve this, I tried using the Motor Profiler to identify the exact motor characteristics, but I am unable to establish a connection with the board (see attached screenshot).

Motor Characteristics:

• Nominal Voltage: 12 VDC

• Rated Speed: 10,000 rpm

• Starting torque: 225 mNm

• Rated Current: 2.18 A

• Winding Resistance (phase-phase): 0.88 Ω

• Winding Inductance (phase-phase): 0.331 mH

• Pole Pairs: 7

Could you please help me identify the cause of the MC_DP_FAULT error and why the Profiler fails to connect?

Best regards,

Jules

Edit 05/02: I have managed to get the motor running; however, I am still unable to establish a connection to the board via Motor Pilot.

Hello @JulesC,

In the MC Pilot Logs tab, open the ST Motor Pilot.ini file shown at the line:
[INFO] - : ini file path=
In the ST Motor Pilot.ini file, set the following parameter:
TerminalVisible = true
Could you share the MC Pilot Terminal tab during the connection step?

Hello @GMA ,

Thank you for the instructions. I have updated the .ini file as requested. Here are the logs from the MC Pilot Terminal tab during the connection step:

Hello @JulesC,

MC Pilot sends a beacon message. Clicking on the ASPEP_BEACON message, MC Pilot displays the decoded message. The message is correctly decoded on the microcontroller unit (MCU) side. On the universal asynchronous receiver transmitter (UART) side, a BEACON response (0x05C70114) is sent, but MC Pilot does not receive it.
Check the USB cable and the STLINK-V3MINI. Try using another PC.

Hello ,

Thank you for your answer.
Actually my colleague and I found that the JP15 link (which should be closed by default) was open. Once we added a wire, we were able to connect to Motor Pilot successfully."
