Gigi or Dino:
I met a strange question, motor parameter in STM3210E+ MB495 successfully entered the closed loop control. Now I redesign custom board,
The open loop mode debugging hardware correctly, when the switch into the normal mode, the motor open-loop liters of normal speed, but has the obvious noise, finally can not enter the closed loop mode, display the start-up Error.
The design of current sampling circuit, whether a rule? I oscilloscope display, amplifying the input 410mv 590mv circuit output amplification ratio 1.46, excuse me whether my T-noise with T-rise did not cause a good?
