4.2 Basic Functions Settings4-94 Operation Related Parameter4.2.4 Electronic GearThe electronic gear enables the workpiece travel distance per reference unit input from the host controller. Theminimum unit of the position data moving a load is called a reference unit.Parameter Meaning When Enabled ClassificationPn00Dn.0[Factory setting] Does not detect overtravel warning. After restart Setupn.1 Detects overtravel warning.When the Electronic Gear is Not Used:Calculate the revolutions.1 revolution is 6 mm. Therefore, 10 ÷ 6 = 10/6 revolutions.When the Electronic Gear is Used:Ball screw pitch: 6 mmWorkpieceEncoder resolution (20 bit) 1048576123The section indicates the difference between using and not using an electronic gear when aworkpiece is moved 10 mm in the following configuration.Calculate the required reference units.1048576 reference units is 1 revolution. Therefore, 10/6 × 1048576 = 1747626.66 reference units.Input 1747627 references as reference units.Reference units must be calculated per reference. → complicatedThe reference unit is 1 μm. Therefore, to move the workpiece 10 mm (10000 μm),1 reference unit = 1 μm, so 10000 1 = 10000 reference units.Input 10000 reference units.÷Calculation of reference units per reference is not required. → simplifiedRotation
