Hi,

I need information about the '' How to setup the new PMSM Motor without sensor to STR 750 Motor Control Kit?''

New Motor Technical Specifications:

12 volts Motor, PMSM Motor.

According to your manual, I setup the Hardware in STR 750 Motor Control Kit for new motor (12Volts) following steps:

Dual power supply, according to manual ( Dual power supply for motors requiring a voltage less than 18 Volts) – J1 (15 V DC, 0.5 A), J3 1- 12 Volts DC

W1 jumper must be removed

But in the micro controller , I got a massage like '' Fault!!!! BUS UNDER VOLTAGE''

Could you please mail me about that problem and Is it possible to run own PMSM motor below 20 Volts with STR 750 Micro controller Kit?

Thanks for advance

Regards

Hello,

The fact is that the undervoltage fault is ON under 20-21V, to make sure that the alignment of the included PMSM motor is done properly (enough current). So if you want to run another motor, you may have to remove the undervoltage protection routine from the stand alone library and recompile the firmware. In main.c, you should remove:

// check bus voltage

if (MISC_Chk_OverVolt() == TRUE)

{

wGlobal_Flags |= OVER_VOLTAGE ;

State = FAULT;

}

else

{

wGlobal_Flags &= ~OVER_VOLTAGE;

}
