9.4 Electronic Gear Function

9.4.1 Overview of Electronic Gear Function

 Electronic gear function
The electronic gear function operates the positioning unit at the speed of the master axis
multiplied by a preset gear ratio.

 Cautions when using the electronic gear function
The use of the electronic gear function makes it possible to set the salve axes to a desired
speed relative to the master axis.
Movement amount of slave axes
= Movement amount of master axis x (gear ratio numerator/Gear ratio denominator)
Do not use the electronic gear function if the movement amount of the master axis needs to
coincide with that of the slave axes.
•
Keep in mind that the slave axes may come to a sudden stop if an
emergency stop or deceleration stop is executed while make a gear ratio
change.
