9-14-7 4620 hex: Encoder Dividing Pulse Output
• For applications for which the number of output pulses per rotation is not an integer, set this object to
a value other than 0. By setting a value other than 0, the number of output pulses per motor rotation
can be set with the dividing ratio which is calculated from the dividing numerator and dividing denom-
inator.
 Description of Set Values
• Selects whether to reverse the encoder dividing pulse output or not.
 Description of Set Values
Subindex 03 hex: Dividing Denominator
Set value Description
0 Number of output pulses per rotation = Encoder Dividing Numerator × 4
Others Number of output pulses per rotation = Encoder Dividing Numerator ÷ Encoder Dividing
Denominator × Encoder Resolution
Subindex 04 hex: Output Reverse Selection
Set value Description
0 Not reverse
1 Reverse
