6 SEQUENCE PROGRAM USED FOR POSITIONING CONTROL
6.5.6 Stop program
The axis stop signal [Y13, Y14, Y1C] or a stop signal from an external source is used
to stop the control. Create a program to turn the axis stop signal [Y13, Y14, Y1C] ON
as the stop program.
The process for stopping control is explained below.
Each control is stopped in the following cases.
(a) When each control is completed normally.
(b) When Servo alarm (Md.116 Servo status: b13) turns ON.
(c) When the PLC READY signal is turned OFF.
(d) When an error occurs.
(e) When control is intentionally stopped. (Stop signal from PLC CPU turned ON, stop
from peripheral device, etc.)
The stop process for the above cases is shown below. (Excluding (a) when the
operation stops normally.)
