Procedure for setting the electronic gear ratio
Step
Operation
Description
1
Check machine specifications.
Check the reduction ratio, ball screw lead, and pulley
diameter.
2
Check the encoder resolution of servo
motor.
Check the number of encoder pulse for one revolution.
3
Travel per command pulse
Determine the travel per command pulse from the
command controller
4
Calculate the number of command pulse
per load shaft revolution
Calculate the number of command pulse for turning load
shaft one revolution based on the previously determined
command unit.
5
Calculate the electronic gear ratio.
Use the electronic gear ratio equation to calculate the ratio
6
Set parameters.
Set parameters using the calculated values.
Setting parameters procedure is as below:
Electric gear ratio

Electric gear
ratio 1
1. Electric gear ratio 1
2. Electric ger ratio 2
3. Terminal selection
Electric gear
ratio 2
When Po304 and Po346 are not 0, electronic gear ratio equals to Po304/Po305 (Po344/Po346). If Po304
(Po344)=0, pulse numbers of motor rotating a rotation is controlled by Po305 (Po304).
3)
Related parameters
It needs 131072 pulses from servo drive to make a 17bit encoder rotate a rotation (when electronic gear is 1).
