4.6.3 Setting the Electronic Gear
(1) Electronic Gear
The electronic gear enables the workpiece travel distance per input reference pulse from the host controller to be set to
any value.
One reference pulse from the host controller, i.e., the minimum position data unit, is called a reference unit.

One revolution is 6mm. Therefore 10÷6＝
1.6666 revolutions.
32768×4 pulses is one revolution.
Therefore, 1.6666×32768×4＝218445
pulses. 218445 pulses are input as
reference pulses.
The equation must be calculated at the
host controller.
To move a workpiece 10mm :
The reference unit is 1µm. Therefore, to
move the workpiece 10mm (10000µm),
1pulse=1µm, so 10000/1＝10000 pulses.
Input 10000 pulses per 10mm of
workpiece movement.
