PBO).
Pulses from motor encoder (PG) are divided by
the preset number of pulses before being output.
The number of output pulses per revolution is set in this user constant. Set this value ac-
cording to the reference unit of the machine or controller to be used.
The setting range varies according to the encoder used.
