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.
Workpiece
Stores the created program.
QD75 errors, etc., are detected.
GX Developer
CPU module
Stores the parameter and data.
Motor
Creates control order and
conditions as a sequence
program.
GX
Configurator
-QP
Sets the parameters and
positioning data for control.
Outputs the start command for
JOG operation, etc., during test
operation with the test mode.
Monitors the positioning operation.
The QD75 outputs the start signal and
stop signal following the stored program.
QD75 positioning
module
Servo
amplifier
Carries out the actual work according to commands
from the servo.
Outputs the drive unit READY signal and
zero signal to the QD75.
Receives pulse commands from QD75, and
drives the motor.
Outputs pulses to the servo according to the
instructions from the CPU module, GX Configurator-QP,
external signals and manual pulse generator.
Manual pulse
generator
External signal
Issues commands by
transmitting pulses.
Outputs signals such as the start
signal, stop signal, limit signal and
control changeover signal to the QD75.
