5-3-3. Electronic gear ratio
The electronic gear function is set any value for motor moving quantity corresponding to
input pulse command. The host device which sends command doesn’t need to consider the
machine deceleration ratio and encoder pulse quantity.

5-3-3-2. Set the electronic gear
Calculate the electronic gear ratio (B/A) using the following steps:
Step
Content
Explanation
1
Confirm the machine
specification
Confirm the deceleration ratio, ball screw distance,
pulley
diameter
2
Confirm the encode

pulse
Confirm the servo motor encoder pulses
3
Set the reference
unit
Set the
actual distance or angle
corresponding to 1 pulse of the
command controller
