6.11.2 Setting electronic gear ratio
Set electronic gear ratio by Pt20E and Pt210.
Note:
(1) If electronic gear ratio is set by controller, the electronic gear ratio of servo drive is usually set to 1:1.
(2) If command pulse input multiplier is enabled, one pulse = n control unit. n = the value of command pulse input
multiplier (Pt218).

Calculating the setting value of electronic gear ratio:
 Rotary servo motor
The reduction ratio of motor shaft and load side is n/m. (When the motor rotates for m revolutions,
the load shaft rotates for n revolutions.) The setting value of electronic gear ratio can be obtained by
the formula below.
