DVP-ES3 Series Programming Manual Function block 2 Explanation When M0 is ON, Y0 outputs 10000 pulse at 1kHz. Y1 = OFF means the pulse output direction is positive. 9. Refer to PLSR instruciton (API2701) for more details on changing target frequency during outputting. 10. Changing the target position during outputting: 10.1 You cannot change outputting direction even after the target position is changed. For example, if the original output target position is in the positive direction, after the target positon is changed, it still outputs in the positive positive. 10.2 After you set the change flag, the changing happens when the instruction is being scanned.
And after it is changed, the change flag is cleared off. But if the target position is set incorrectly, the change flag keeps ON. 10.3 Refer to the following table for the corresponding outputs and change flag SM. _6 10.4 This changing target posiiton funciton is available for DDRVI and DDRVA insturcitos. When the instruction DDRVI is used and a change flag is set, the change will be executed. Even if the output number is 0, the operation will be carried out and stop outputting. When the instruction DDRVA is used, if the changed target position is the same as the previous one, this change will not be performed. 10.5 Three situations may occur, when changing target position during output.
Situation A: changing timing occurs during outputting in the ramp-down area. oringinal target position when started (blue) new number of output pulse >= remaining number of output pulse, its outputting curve (red). new number of output pulse 6-802 Output point Y0 Y1 Y2 Y3 Y4 Y5 Y6 Y7 SR number SM478 SM479 SM498 SM499 SM518 SM519 SM538 SM539
