• Use the following user constant to set the pulse dividing ratio.
PGRAT
Dividing Ratio
Cn-0A
Setting
Set the number of output pulses for PG output
signals (PAO, PAO, PBO and
*
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 accord-
ing to the reference unit of the machine or con-
troller to be used.
The setting range varies according to the en-
coder used.
