You can change the number of output pulses by setting the dividing ratio.
The number of output pulses is determined as follows when Encoder Dividing Pulse Output - Divid-
ing Denominator (4620-03 hex) is set to 0.
The number of output pulses is determined as follows when Encoder Dividing Pulse Output - Divid-
ing Denominator (4620-03 hex) is set to a value other than 0.

Encoder Dividing Pulse
Output
Sets the encoder dividing pulse output. P. 9-114
01 Enable Selects whether to enable or disable the
encoder dividing pulse output function.
0: Disabled
1: Enabled
P. 9- 114
02 Dividing Numerator Sets the number of output pulses per motor
rotation.
P. 9- 114
03 Dividing Denominator For applications for which the number of out-
put pulses per rotation is not an integer, when
this set value is set to a value other than 0, the
number of output pulses per motor rotation
can be set by the use of the dividing ratio
which is calculated from the dividing numera-
tor and dividing denominator.
P. 9- 115
04 Output Reverse Selec-
tion
Selects whether to reverse the encoder divid-
ing pulse output or not.
0: Not reverse
1: Reverse
P. 9- 115
