Magnetic pole initial position will be updated automatically after autotunning of
synchronous motor, the parameter shouldn’t be modified.
Note: For the magnetic pole initial position, its corresponding angle is electric
angle.

Thread break detection time of encoder is defined by P4.04 and P4.05, when the time
of encoder thread break is more than setting time of encoder thread break, the inverter
will show fault of encoder thread break (PCE), P4.04 corresponds to low speed, and
P4.05 corresponds to high speed.
Reverse detection time of encoder is defined by P4.06, when the time of reverse time
of encoder is more than corresponding thread break detection time, the system will
show fault of encoder reverse encoder (PCDE).
If the detection time is set to be 0, it means the detection function been canceled.
Note: Setting the above parameters will influence delicacy of encoder fault
protection, please adjust these parameters carefully.
