Fixed Length Processing
Overview
In the example, a transfer roller with external cicumference of 10cm
and 10cm movement of lead cable by one rotation is used.
With this roller, slow the rotation when lead cable moves 95cm, and
stop rotation at 100cm(10 rotations).
In this example, the resolution of encoder is 500 pulses/rotation. Also,
pulse output is not used, and inverter start/stop is controlled by CMP0
signal, and high/low speed is controlled by CMP1 signal.

For more precise measurements, pulse output function can be used and the
inverter can be replaced with a servo drive.
