7 Absolute Position Detection
7.3.2 Infinite Length Axis
7-26
The following programming example (ladder program) is for the flowchart shown on the previous
page. The axis used here is axis 1 of circuit number 1. Change the motion parameter register number
if the circuit and axis numbers are different.
EXAMPLE
Absolute system infinite length axis: Axis 1 Leading address of toggle buffer: MW30000
ON for only the first scan after high-speed scan is started.
