Using the two-phase high-speed counter, the pulses from a rotary encoder are input to the FC6A Series MicroSmart and a
continuous workpiece is marked at a regular interval.
Application description
In the WindLDR Function Area Settings, select Two/Single-phase High-speed Counter for Group 1.
In the High-speed Counter Settings dialog box, configure the settings as follows.
• The rotary encoder pulses are input to external input
I0. 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.
