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

Move distance of work per 1 turn of motor axis: 10mm
・ Minimum resolution of external encoder (multiplied 4): 1.0×10

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

= 10,000 P/R (multiplied 4)
Index 0x20FF-3 "External encoder resolution" is "multiplied 1" value (amount of phase-A
or phase-B), so the value below is set.
External encoder resolution = 10,000/4 = 2,500 P/R
* Round off the value to the whole number.
