8.5.7 Encoder Signal Output
Encoder feedback pulses processed inside the SERVOPACK can be output externally.
The following signals are added when using an absolute encoder.
* SG (CN1-1, 2): Connect to 0 V on the host controller.
Dividing
The dividing means that the divider converts data into the pulse density based on the pulse data of the encoder installed on
the servomotor, and outputs it. The setting unit is the number of pulses/revolution.

Output PCO CN1-19 Encoder output phase C (zero-point pulse)
/PCO CN1-20 Encoder output phase /C (zero-point pulse)
* Even in reverse rotation mode (Pn000.0 = 1), the dividing output phase form is the same as that for the standard setting
(Pn000.0 = 0).
