9.1.5.4 Feedback pulse setting
■
External incremental encoder resolution
Sets pulse amount (multiply 1) of external encoder per 1 turn of motor axis.
Be valid after control power cycle.

Setting sample
[Use condition]
・
Move distance of work per 1 turn of motor axis: 10mm
・ Minimum resolution of external encoder (multiplied 4): 1.0×10
-3
mm (=1.0 μ m)
[Setting value]
Move distance of work per 1 turn of motor axis is 10mm, and Minimum resolution of
external encoder is 1.0
μ m, so,
Pulse amount of external encoder per 1 turn of motor axis
=
= 10mm /(1.0
×
10 -3 mm)
= 10000 P/R (multiplied 4)
System parameter ID22 "External encoder resolution" is "multiplied 1" value (amount of
phase-A or phase-B), so,
External encoder resolution = 10000/4 = 2500 P/R
set this value.
✔
Round off the value to the whole number.
