Parameter name
Set the number of command pulses
corresponding to 1 motor rotation.
Set the numerator of the electronic
gear ratio for the command pulse
input.
Set the denominator of the electronic
gear ratio for the command pulse
input.
Parameter name
Set the number of phase A and
phase B output pulses, respectively
per motor rotation.
Select the phase B logic for pulse
regeneration output and the output
source. For fully-closed control,
select an external encoder for the
output source.

When the number of output pulse per
rotation is not an integer, you can set
a dividing ratio by setting the set
value here to a number other than 0,
and using Pn011 as the dividing
numerator and Pn503 as the dividing
denominator.
