6 SEQUENCE PROGRAM USED FOR POSITIONING CONTROL
6.5.6 Stop program
The axis stop signal [Y4, Y5, Y6, Y7] or a stop signal from an external source is used
to stop the control.
Create a program to turn ON the axis stop signal [Y4, Y5, Y6, Y7] as the stop program.
The process for stopping control is explained below.
Each control is stopped in the following cases.
to stop the control.
Create a program to turn ON the axis stop signal [Y4, Y5, Y6, Y7] as the stop program.
The process for stopping control is explained below.
Each control is stopped in the following cases.
(1) When each control is completed normally.
(2) When the drive unit READY signal is turned OFF.
(3) When a CPU module error occurs
(4) When the PLC READY signal is turned OFF.
(5) When an error occurs in QD75.
(6) When control is intentionally stopped
(2) When the drive unit READY signal is turned OFF.
(3) When a CPU module error occurs
(4) When the PLC READY signal is turned OFF.
(5) When an error occurs in QD75.
(6) When control is intentionally stopped
(Stop signal from CPU module turned ON, stop signal from peripheral devices)
The stop process for the above cases is shown below.
