Z phase correction margin
Judge the pulse deviation value of the AB phase between to neighboring Z phase. Technically, the deviation
value=09-01（P.350） [or 4*09-01（P.350）] , convert into mechanical angle with 360 degrees. When subtracting
09-01 （P.350）[or 4*09-01（P.350）] from the deviation is lesser than 09-14（P.363）, and the deviation is greater
than 09-04(P.353)，execute Z phase correction.
When Z phase is disturbed by external factors, set 09-14(P. 363) to 0..
Note: Only valid when PM motor is in VC modem motor in position mode.

Enable DV1/DV2 alarm of phase Z
DV1 is the alarm when Z phase is lost，DV2 is the alarm when noise in Z phase is detected. When 05-15（P.364）
=0，DV1,DV2 can be canceled.
Note:
Only valid when 00-21（P.300）=5

Encoder mounting transmission ratio
If the encoder is not installed on the motor shaft and the transmission ratio is not 1:1, this parameter shall be set.
The relation between parameters 09-17 (P.416) and mechanical installation is as follows: motor speed/encoder
