90° Phase Difference Output Type External Encoder
 Phase Z is output without dividing the Z signal that is input from the 90
type external encoder.
 When 90 °
Phase Difference Output External Encoder Pulse Output Method Selection (Pn622) =
1, the phase AB signal can be input into the amplifier and regenerated. Note, in this case, that the
phase-AB regeneration will be delayed compared to when Pn622 is set to 0.
External Encoder Common Items
 When detection cannot be made because the phase-Z signal width is narrow due to the external
encoder travel distance, if you set the phase-Z signal output time in the External Encoder-Z
Setting (Pn620), phase Z can be output at least for that period of time.
In addition, take note that the output is made from when the phase-Z signal starts and, therefore,
it will be different from the actual phase-Z signal width. Take note, also, that the direction of the
time extension varies depending on the direction of the operation.
