Encoder Phase-
Z Setting
Finely adjust the ON width of encoder 
phase-Z signal output.
This is enabled when the phase-Z output 
and phase-A output are not synchronized 
(Pn011/Pn503 
× Encoder resolution is not a 
multiple of 4) due to the encoder dividing 
ratio setting.
The set value of Pn619 and the ON width of 
phase-Z output are related as follows:
Phase-Z output width [s] = 30/(Pn619 
× 
Motor speed [r/min])
