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 for using the electronic gear function.
The use of the electronic gear function makes it possible to set the slave axes to a desired
speed relative to the master axis. The movement amount of the slave axes, however, is
obtained from the following formula. Therefore, the movement amount of the master axis does
not coincide with that of the slave axes.
Movement amount of slave axes = Movement amount of master axis x (gear ratio
numerator/Gear ratio denominator)
* On the condition that the gear ratios are constant.
Do not use the electronic gear function if the movement amount of the master axis needs to
coincide with that of the salve axes.
Keep in mind that the slave axes may come to a sudden stop if an emergency stop or
deceleration stop is executed while making a gear ratio change.
