CalibratedAngle 问题



在TI提供PMSM3.1内容中的F281XQEP.C 里有一个参数:p->CalibratedAngle ,请问题这个参数如何调节?代表什么意义?在 F281XQEP.H  仅有说明:

// Applied-motion PMSM motor: 24-v, 8-pole, 2000 line encoder, CalibratedAngle = -1250

// MechScaler = 1/8000 = 0x00020C4A (Q30)

// PacSci 1-hp PMSM motor: 320-v, 4-pole, 1000 line encoder, CalibratedAngle = -2365

// MechScaler = 1/4000 = 0x00041893 (Q30)
