Electronic Gear Ratio Denominator
Setting
30
1 to 2
range
 Set the electronic gear function.
· It is enabled when Pn008 is 0.
 The electronic gear can be used for the following:
· 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).

Any values can be set for PN008, Pn009, and Pn010, but operation may not be correct if you
set an extreme electronic gear ratio. Set the electronic gear ratio to between 1/1,000 and
1,000. Refer to "6-4 Electronic Gear Function" (P.6-10) for information on the settings.
Pn011
Encoder Dividing Numerator
Setting
1 to 262,144
range
 If Encoder Dividing Denominator (Pn503) = 0, the encoder resolution becomes the pulse output dividing denominator.
 Note that 1 pulse corresponds to 4 counts. Encoder resolution corresponds with counts.

Encoder Output Direction Switching Selection
Setting
0 to 3
range
 Set the phase-B logic and output source for pulse output. For fully-closed control, select an
external encoder for the output source. For other control modes, set the encoder.
