Start program
This program is used to start the control with start commands.
The control can be started with the following two methods.
• Starting by inputting positioning start signal [Y10, Y11, Y12, Y13]
• Starting by inputting external command signal
[Starting conditions]
To start the control, the following conditions must be satisfied.
The necessary start conditions must be incorporated in the program so that the control is not started when the
conditions are not satisfied.
*1
When the synchronous setting of the CPU module is made in the nonsynchronous mode, this must be provided as an
interlock.
If it is set to the synchronous mode, it must not be inserted in the program for interlocking because it is turned ON when
the CPU module executes calculation.
1)
Set the "positioning start No." corresponding to the control to be started in "[Cd.3] Positioning start No.". (In the above example, set
positioning data No. "1".)
2)
Input the positioning start signal [Y10] or the external command signal.
3)
The positioning data No. "1" will start.
