■
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.

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
