8-1 Basic Parameters
Pn008
Electronic Gear Integer Setting
Setting
0 to 2
range
Set the number of command pulses corresponding to 1 motor rotation.
If the set value is 0, Electronic Gear Ratio Numerator 1 (Pn009) and Electronic Gear Ratio
Denominator (Pn010) become valid.

The electronic gear ratio is set using the following equations.
If Numerator = 0: Numerator is automatically set to encoder resolution, and the number of
command pulses per rotation can be set in Pn010.

· It is enabled when Pn008 is 0.
· To set the amount of motor rotation or travel distance per input command pulse.
· To increase the nominal command pulse frequency by using a multiplier when the desired
motor speed cannot be achieved due to the limited pulse generation capability of the host
device (possible maximum output frequency).
