(3) Motion Program Control Signals
To execute a motion program called from a DWG.H by the MSEE instruction, program control signals (such as
program start requests and program stop requests) must be input. The second word in the MSEE work registers
contains the control signals. The signals used to control motion programs are shown in the following table.
* 1. System Work Number Setting
OFF: The system work number is automatically defined by the system. The system work number may be different each
time.
ON: The system work number can be set with the fourth word of MSEE work register.
* 2. Interpolation Override Setting
OFF: Interpolation override fixed at 100%.
ON: The interpolation override set with third word of MSEE work register is used.
For the ladder program inputs, make sure the signals are in accordance with the signal type.
The program will be executed if the program start request signal has been turned ON when the power is
turned ON.
The following illustration shows the method of executing a motion program.
