I am afraid you need to connect HVP-KV46F150M daughter card with HVP-MC3PH power stage.

If your project run into MC_FAULT_SET(gsM1Drive.sFaultIdPending, MC_FAULT_LOAD_OVER); during debug.
You need to trace why these three variables meet the case.
gsM1Drive.sSpeed.f16SpeedFilt
gsM1Drive.sSpeed.f16SpeedRamp
gsM1Drive.sSpeed.bSpeedPiStopInteg

Best Regards,

Hi Robin

Great thank for your care, when do steps in 8.1. Running the motor the PWM  magnitude about 1v then disappear when fault overload (on) this happen without connect power board(KV46F150M only).

[Robin_Shen]

Please download Sensorless PMSM Control Design(DRM148).
The overload Fault is detected in M1_FaultDetection function.
The PWM output is disabled in some states.

Robin

Hi
Please read the PMSMCRSPUG in MCRSP_PMSM_V1.1.2 folder.

If the communication between KV46 and FreeMASTER is established successfully?

Please run the demo according to "8.1. Running the motor".

Best Regards,

Robin
