„ Electronic Gear Ratio
Set the electronic gear ratio using Pn20E and Pn210.
If the gear ratio of the servomotor and the load shaft is given as n/m where m is the rotation of the servomotor and n
is the rotation of the load shaft,
„ Encoder Resolution
Encoder resolution is 65536.
Electronic gear ratio setting range: 0.01 ≤ Electronic gear ratio (B/A) ≤ 100
If the electronic gear ratio is outside this range, a parameter setting error 1 (A.040) will be output.
