The minimum unit of the position data that is used to move a load is called the reference
unit. The reference unit is used to give travel amounts, not in pulses, but rather in dis-
tances or other physical units (such as μm or °) that are easier to understand.
The electronic gear is used to convert the travel distances that are specified in reference
units to pulses, which are required for actual movements.
With the electronic gear, one reference unit is equal to the workpiece travel distance per
reference pulse input to the SERVOPACK. In other words, if you use the SERVOPACK’s
electronic gear, pulses can be read as reference units.
The difference between using and not using the electronic gear is shown below.
