Sets the number of output pulses for PG output sig-
nals (PAO,
/
PAO, PBO and
/
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 parameter. 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.
