Outline of Motion Control Systems
( 2 ) Motion Program Control Signals (DA
+1)
Program control signals (e.g., program operation start requests and program stop requests) need to be entered to exe-
cute the motion program called from DWG.H using the MSEE command. The second word of the MSEE work regis-
ters (DA
+1) is the motion program control signal.
The following types of signals for controlling motion programs are available.
These signals can perform run, stop, hold, and other controls for motion programs by entering from the ladder program
to the work register specified by the MSEE c1.
Use signals conforming to the above signal types when writing ladder programs.
Motion programs are executed if the program operation start request signal is ON when the power is turned ON
(e.g., when a start request signal is left in M register).
