请问大侠，能不能解释一下HAL_setupFaults函数的用途。
我用的平台是C2000Ware_MotorControl_SDK_3_00_01_00，芯片是F280049C，控制单马达。
现在在我这里HAL_setupFaults需要直接返回，这样电机可以运行，运行参数正常。
如果HAL_setupFaults不直接返回，而是运行里里面内容，那么运行程序时电机不转，也不拉电流，也没有出错。
void HAL_setupFaults(HAL_Handle handle)
{
HAL_Obj *obj = (HAL_Obj *)handle;
uint16_t cnt;
// return;
// Configure Trip Mechanism(ÌøÕ¢»úÖÆ) for the Motor control software
// -Cycle by cycle trip on CPU halt
// -One shot fault trip zone
// These trips need to be repeated for EPWM1 ,2 & 3
// configure the input x bar for TZ2 to GPIO, where Over Current is connected
// XBAR_setInputPin(XBAR_INPUT2, HAL_PM_nFAULT_GPIO);
// XBAR_lockInput(XBAR_INPUT2);
for(cnt=0;cnt<3;cnt++)
{
EPWM_enableTripZoneSignals(obj->pwmHandle[cnt],
EPWM_TZ_SIGNAL_CBC6);
EPWM_enableTripZoneSignals(obj->pwmHandle[cnt],
EPWM_TZ_SIGNAL_OSHT2);
//enable DC TRIP combinational input
EPWM_enableDigitalCompareTripCombinationInput(obj->pwmHandle[cnt],
(EPWM_DC_COMBINATIONAL_TRIPIN7 |
EPWM_DC_COMBINATIONAL_TRIPIN8 |
EPWM_DC_COMBINATIONAL_TRIPIN9),
EPWM_DC_TYPE_DCAH);
EPWM_enableDigitalCompareTripCombinationInput(obj->pwmHandle[cnt],
(EPWM_DC_COMBINATIONAL_TRIPIN7 |
EPWM_DC_COMBINATIONAL_TRIPIN8 |
EPWM_DC_COMBINATIONAL_TRIPIN9),
EPWM_DC_TYPE_DCAL);
EPWM_enableDigitalCompareTripCombinationInput(obj->pwmHandle[cnt],

EPWM_DC_COMBINATIONAL_TRIPIN8 |

(EPWM_DC_COMBINATIONAL_TRIPIN7 |
EPWM_DC_COMBINATIONAL_TRIPIN8 |
EPWM_DC_COMBINATIONAL_TRIPIN9),
EPWM_DC_TYPE_DCBL);
// Trigger event when DCAH is High
EPWM_setTripZoneDigitalCompareEventCondition(obj->pwmHandle[cnt],
EPWM_TZ_DC_OUTPUT_A1,
EPWM_TZ_EVENT_DCXH_HIGH);
// Trigger event when DCBH is High
EPWM_setTripZoneDigitalCompareEventCondition(obj->pwmHandle[cnt],
EPWM_TZ_DC_OUTPUT_B1,
EPWM_TZ_EVENT_DCXL_HIGH);
// Enable DCA as OST
EPWM_enableTripZoneSignals(obj->pwmHandle[cnt], EPWM_TZ_SIGNAL_DCAEVT1);
// Enable DCB as OST
EPWM_enableTripZoneSignals(obj->pwmHandle[cnt], EPWM_TZ_SIGNAL_DCBEVT1);
// Configure the DCA path to be un-filtered and asynchronous
EPWM_setDigitalCompareEventSource(obj->pwmHandle[cnt],
EPWM_DC_MODULE_A,
EPWM_DC_EVENT_1,
EPWM_DC_EVENT_SOURCE_FILT_SIGNAL);
// Configure the DCB path to be un-filtered and asynchronous
EPWM_setDigitalCompareEventSource(obj->pwmHandle[cnt],
EPWM_DC_MODULE_B,
EPWM_DC_EVENT_1,
EPWM_DC_EVENT_SOURCE_FILT_SIGNAL);
// What do we want the OST/CBC events to do?
// TZA events can force EPWMxA
// TZB events can force EPWMxB
EPWM_setTripZoneAction(obj->pwmHandle[cnt],
EPWM_TZ_ACTION_EVENT_TZA,
EPWM_TZ_ACTION_LOW);
EPWM_setTripZoneAction(obj->pwmHandle[cnt],
EPWM_TZ_ACTION_EVENT_TZB,
EPWM_TZ_ACTION_LOW);
// Clear any spurious fault
EPWM_clearTripZoneFlag(obj->pwmHandle[cnt],
HAL_TZ_INTERRUPT_ALL);
}
return;
} // end of HAL_setupFaults() function

请问您是否进入该函数并单步调试？
另外您现在使用的硬件以及软件是什么？能否请您详细描述一下？
