Example program 2
Using the two-phase high-speed counter, the pulses from a rotary encoder are input to the SmartAXIS and a continuous
workpiece is marked at a regular interval.
Application description
• The rotary encoder pulses are input to external inputs
I0 and I1. A continuous sheet of paper is marked
(holes are punched) at a regular interval (every 2,700
pulses).
• The rotary encoder is directly connected to the paper
feed roller, and output pulses are counted by the
high-speed counter and controlled.
• The cycle time is the time to count 2,700 pulses.
When the hole punch time is 0.5 seconds, the
operation condition is 2,700 pulse count time > 0.5
seconds.
In WindLDR Function Area Settings, select Two/Single-phase High-speed Counter for Group 1.
In High-speed Counter Settings, configure the settings as follows.
