TMS320F28027: 24.0 Set to Vbus

Part Number: TMS320F28027
Other Parts Discussed in Thread: MOTORWARE, BOOSTXL-DRV8305EVM

你好,

例子  C:\ti\motorware\motorware_1_01_00_18\sw\solutions\instaspin_foc\boards\boostxldrv8305_revA\f28x\f2802xF\projects\ccs\proj_lab11a

#define USER_IQ_FULL_SCALE_CURRENT_A         (24.0) // BOOSTXL-DRV8305EVM = 24.0 A

上面方框里提到 必要条件 

USER_IQ_FULL_SCALE_VOLTAGE_V > 0.5 * USER_MOTOR_MAX_CURRENT * USER_MOTOR_Ls_d * USER_VOLTAGE_FILTER_POLE_rps

如果24.0 小了,那该设为多少?   改了后电压采样倍数就不对了,

2,

电流的24 也小了,该设为多少,可以翻倍吗?采样部分也需要改是吗?

 是改这里吗?这个IQ12mpy  ()是啥功能?
