5.4 Electronic Gear
The electronic gear enables the workpiece travel distance per reference pulse input from the host controller. The
minimum unit of the position data moving a load is called a reference unit.
When the Electronic Gear is Not Used:
Calculate the revolutions.
1 revolution is 6 mm. Therefore, 10 ÷ 6 = 1.6666 revolutions.
Calculate the required reference pulses.
65536 pulses is 1 revolution. Therefore, 1.6666 × 65536 = 109222 pulses.
Input 109222 pulses as reference pulses.
Reference pulses must be calculated per reference.

When the Electronic Gear is Used:
The reference unit is 1
μm. Therefore, to move the workpiece 10 mm (10000 μm),
1 pulse = 1
μm, so 10000 ÷ 1 = 10000 pulses.
Input 10000 pulses as reference pulses.
Calculation of reference pulses per reference is not required.
