7.1.8 Setting electronic gear
1
）
Electronic gear
At the position control mode, input position command (command unit) is used to set load
displacement, motor position command (Encoder unit) is used to set motor displacement.
Electronic gear ratio is used to set proportional relation between motor position command and
input position command.

Procedure for setting the electronic gear ratio
Step Operation Description
1 Check machine specifications.
Check the deceleration ratio, ball screw pitch, and
pulley diameter.
2
Check the number of encoder
pulses. Check the number of encoder pulses for the servo
motor used.
3
Determine the command unit
used. Determine the command unit from the command
controller
4
Calculate the travel distance
per load shaft rotation.
Calculate the number of command units necessary
to turn the load shaft one rotation based on the
previously determined command units.
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:
When 2003h-05h and 6091h-01h are not 0, electronic gear ratio equals to 2003h-05h/2003h-06h
(or 6091h-01h/6091h-02h). If 2003h-05h or
（
6091h-01h
）
=0, pulse numbers of motor rotating a
rotation is controlled by 2003h-06h or
（
6091h-02h
）
.
