Encoder Output Direction Switching Selection (Pn012)
The corresponding external encoders for each output type are given in the following table.
External Encoder Pulse Regeneration Function
Serial Incremental External Encoder
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.
*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).
