4.1.1 Setting of Electronic Gear Ratio
Setting the electronic gear is to set different data unit for different machines. Different axis of the same
machine can be set based on different unit. For example, axis A can be set as mm, axis B can be set as angle,
and axis C can be set as round.
How to set the numerator and denominator of electronic gear ratio:
Pulse needed for the motor to turn one round to the same direction
Distance moved when the motor turn one round to the same direction(μm)
Numerator and denominator both should be integer between 1 and 99999.
Ex. 1 Screw Transmission
Stepper motor stepping is 5000, or servo motor 5000 pulse/round, screw pitch is 6mm, reduction ratio is 1:1,
then,
5000 → 5
6*1000*1.0 → 6
Ex. 2 Rack and Pinion
Stepper motor stepping is 6000, or servo motor 6000 pulse/round, gear teeth number is 20, m=p/π=2, then
6000 → 1 → 107 → 107
1000*20*2*3.14159265 → 20.943951 → 2241.00276 → 2241
Ex. 3 Rotary Angle
Stepper motor stepping is 5000, or servo motor 5000 pulse/round, reduction ratio is 1:30, then,
5000*30 → 5
360*1000 → 12
4.2 Speed
● X/Y/Z/C Highest: The highest speed of x axis motor. When the system is operating, speed will not
exceed this number no matter what F you set.
● Start(mm/min)Speed during Spd+Time
● Man High: Manual high speed
● Man Low: Manual low speed
