Sigma II User's Manual
This parameter sets the number of output pulses for PG output signals (PAO, /PAO,
PBO, /PBO).
Pulses from the motor encoder (PG) are divided by the number of pulses set here
before being output.
The set value is the number of output pulses per revolution. Set this value according
to the reference unit of the machine or controller to be used.
The setting range varies according to the encoder used.

Transferring Alarm Contents
When an absolute encoder is used, SEN signals can be utilized to transfer the alarm
contents through PAO outputs to the host device as serial data.
