Phase Z is output without dividing the phase Z of the serial incremental external encoder. In
addition, take note that there are differences as illustrated in the figure below depending on the
direction passing phase Z.
Phase A
Phase B
Phase Z
*1. Phase-Z position and its relationship with phases A and B vary depending on the scale.
*2. Phase Z is regenerated for 1 pulse. If the width is narrow, the output time can be extended by the External Encoder
Phase Z Setting (Pn620).
