TMS320F280049C: is06_torque_control 例程IdqSet_A.value[1]设置成负数

Part Number: TMS320F280049C
Other Parts Discussed in Thread: C2000WARE

在is06_torque_control程序中,我将IdqSet_A.value[1]设置成0.5或者1时,电机正常运转,我把它设置成0,电机停止。此时我将dqSet_A.value[1]设置成-0.5或者是-1时,电机就不可以正常旋转了(慢慢抖动).

从我的理解,IdqSet_A.value[1]设置为负数,电机应该往相反的方向进行旋转才对。

请问这可能是什么原因导致的?

谢谢
