The deceleration ratio of the servomotor and the load shaft is given as n/m where m is therotation of the servomotor and n
is the rotation of the load shaft.

·If the ratio is outside the setting range, reduce the fraction (both numerator and denominator) until you obtain integers
within the range.
·Be careful not to change the electronic gear ratio (B/A).
■Important
·Electronic gear ratio setting range: 0.01≤electronic gear ratio(B/A)≤ 100
·If the electronic gear ratio is outside this range, the servo drive will not operate properly. In this case, modify the load
configuration or reference unit.
