1.1.3 Mechanism of positioning control
Positioning control using the QD75 is carried out with "pulse signals". (The QD75 is a
module that generates pulses). In the positioning system using the QD75, various
software and devices are used for the following roles. The QD75 realizes complicated
positioning control when it reads in various signals, parameters and data and is
controlled with the CPU module.
