Countermeasure for vibration when completion of magnetic pole position estimation
In case of Pr9.20 (Selection of magnetic pole detection method) is 2 (magnetic pole position estimation method),
vibration may generate because command position turns to be valid when magnetic pole position estimation is
completed during CP control. There are two possible measures for this.
Using CMD-POS_Invalid bit to make command position invalid during magnetic pole position estimation.
Making command position follow during magnetic pole position estimation.
