High-Speed Counter and Pulse Output

8.1 Overview

Three built-in hardware extensions allow the FP0R to be used for positioning control and
measurement: high-speed counting, pulse output, and PWM (pulse-width modulation) output.
High-speed counter function
The high-speed counter function counts external inputs such as those from sensors or
encoders. When the count reaches the target value, this function turns the desired output to
TRUE or to FALSE.

Pulse output function
By connecting a commercially available motor driver to the PLC, positioning control can be
performed with the pulse output function. Using special instructions, trapezoidal control, home
return, or JOG operation is possible.
