4.2.4 Electronic Gear

The electronic gear enables the workpiece travel distance per reference unit input from the host controller. The
minimum unit of the position data moving a load is called a reference unit.
The section indicates the difference between using and not using an electronic gear when a
workpiece is moved 10 mm in the following configuration.
When the Electronic Gear is Not Used:
1 Calculate the revolutions.
1 revolution is 6 mm. Therefore, 10 ÷ 6 = 10/6 revolutions.
2 Calculate the required reference units.
1048576 reference units is 1 revolution. Therefore, 10/6 × 1048576 = 1747626.66 reference units.
3 Input 1747627 references as reference units.
Reference units must be calculated per reference. → complicated
When the Electronic Gear is Used:
The reference unit is 1 μm. Therefore, to move the workpiece 10 mm (10000 μm),
1 reference unit = 1 μm, so 10000
Input 10000 reference units.
Calculation of reference units per reference is not required. → simplified
Does not detect overtravel warning.
Detects overtravel warning.
