Executing Motion Programs
To execute a motion program called from a DWG.H drawing by the MSEE instruction, pro-
gram control signals (such as program operation start requests and program stop requests)
must be input. Operations are enabled by inputting the external control signals defined on the
Group Definition Window as the program control signals.
1. The signals used to control motion programs are shown in the following table.
2. The motion program operation, stop, pause, and so on, can be controlled by using a lad-
der logic program to input these signals into the one register higher than the work regis-
ter specified with the MSEE instruction.
For the ladder logic program inputs, make sure the signals are in accordance with the sig-
nal type.
When the start signal is input using an NO contact, the program is completed and then restarted. The
program will not be executed if the start signal has been turned ON when the power is turned ON.
