Question

EVLSPIN32G0A2 3 shunt mode not supported in MC workbench 6.4.2?

I have been trying to use the motor profiler to characterize a motor that I do not have full specs for. I am getting “firmware is not a profiler fw….” which took me down the Application Configuration road in the MC workbench. There I discovered that the Profiler check box did not exist. That led me to the Current Sensing configuration section where the following is displayed:

  • Current Mode is off and grayed-out
  • Current Reading Selected hardware boards do not support this feature

The EVLSPIN32G0A2 of course, is a 3 shunt board. I am running 6.4.2 of the MC workbench. So what is happening here? I’m fairly new to this toolchain and thinking there’s a work-around someplace. For a little more context, I am trying to run a 6-step model with a Hall-sensored motor. I can get things to run in Pilot but there’s wonky stuff going on with the GUI. Thinking some of these observations may be related to the current sensing topo as well?

Hello ​@cjf,

As mentioned in the Motor Profiler Application Note available from "Workbench tool">About>Documentations>Documentation "User manual" Tab: 

The Motor Profiler algorithm is provided into the MCSDK FW as a library linkable and compliable with ARMv7 and ARMv8 architecture. The algorithm runs only on the ARM architectures with FPU embedded. In consequence It is not possible to generate a motor profiler binary with the STM32F0, STM32G0, STM32C0 families.

OK - I stopped at “ARM” and didn’t realize it was later gens w/FPU. But why does MC Workbench say the  EVLSPIN32G0A2 does not support current sensing in 6-step config? Again, some GUI wigits are not functional such as speed, etc. despite having Hall setup.

Hello ​@cjf,

Current Mode and Current Reading are part of Sensor Less feature that is not supported by this board (refer to Sensor-less algorithm chapter of the Six-step Firmware Algorithm document available in "Workbench tool">About>Documentations>Documentation "User manual" tab). 6-step model with Hall-sensored speed sensing is the default mode for this board.
