1.1.3 Mechanism of positioning control
Positioning control using the AD75 is carried out with "pulse signals". (The AD75 is a
module that generates pulses). In the positioning system using the AD75, various
software and devices are used for the following roles. The AD75 realizes complicated
positioning control when it reads in various signals, parameters and data and is
controlled with the PLC CPU.
Creates control order and
conditions as a sequence
program.
Stores the created program.
The AD75 outputs the start signal and
stop signal following the stored program.
AD75 errors, etc., are detected.
