Motor Profiler Stops at 7% and driver protection (STM32F446 + STEVAL-IPMM15B)

[Yuan0911]

Hello,

We are using STM32 Motor Profiler to identify the parameters of an IPMSM motor, but the profiling process always stops at approximately 7% and reports a “Driver Protection” fault.

Hardware configuration: - MCU board: NUCLEO-F446RE - Motor-control expansion board: X-NUCLEO-IHM09M2 - Power board: STEVAL-IPMM15B -

Motor type: IPMSM 

 

Thank you.

Hello ​@Yuan0911,

Refer to the “4. resistorOffset parameter computation with the Motor Profiler tool” chapter of the Motor Profiler Application Note document. This document is available in the Workbench tool: About > Documentations > Documentation > User manual.

We have read the user manual and conducted the experiment according to its instructions. However, the driver protection fault is still being triggered.

We have checked the following:

• The wiring and settings of SW1, SW2, SW4, SW5, SW6, SW7, and SW8

• The known motor resistance measured between the U, V, and W phases

• The use of two ADCs

The driver protection fault is triggered immediately when we click “Offset Detection.” However, after pressing “Ack Fault,” the driver protection warning disappears immediately.

What could be causing this issue?

In addition, the progress remains stuck at 7% during both “Offset Detection” and “Start Profiler.”

 

Should I extend digital filter duration.

Hello ​@TyrantRenre,

Does the power board have the following configuration?

• Set SW5, SW6, SW7, and SW8 to the 3-shunt topology.
• Set SW1, SW2, and SW4 to jumper position 1-2 for amplification.
• Connect the DC supplies to J1 and J4.
