Set P2.071 to 0x0001 to reset the current absolute position of the encoder. The clearing function is
enabled by setting P2.008 to 271 and P2.069.X to 1.

YX: range of filter (0 - 95%)
When DI.ALGN is triggered, the E-Cam phase alignment function is enabled. The system detects
the current E-Cam position. When the difference (in percentage) between the current E-Cam
position and its previous alignment position is less than the value set by the parameter, the filter
function is enabled. Otherwise, the system uses the new position to do the alignment.
Note: using the filter allows the alignment to be more stable and reduces any position errors caused by DI
noise, so the operation can be smoother.

UZ: maximum allowable correction rate (0 - 100%)
When phase alignment is enabled, the limitation of the maximum allowable correction rate (C) is
defined as ｜C｜≤ (P5.084/P5.083) x P2.073.UZ %.
Note: when the alignment error is too large, correcting this error once may cause motor vibration or
overloading. Using this parameter can divide the phase alignment into several stages to smooth the process,
but it may need more time to complete the phase alignment.
