can I use the breakpoints like this?

[soslotos]

I try to use the modulo breakpoints and the relative breakpoints together to create a row by row scan .
Can I design like that

Hello,

Yes, modulus breakpoints can be used to generate pulses at even intervals through your moves. To do this, you would load your initial breakpoint position to determine what position value will be used for the first breakpoint and then set the breakpoint modulus to determine the position interval for subsequent breakpoints to be set. If your motion will be occurring in a grid, you can reset your breakpoint position for each line and then reload the modulus for the reverse direction.

Try this and let me know if you have any additional questions on this issue.

Hi,

As a heads up, the NI-735x motion controllers have a feature called Periodic Breakpoints. These have the same behavior as the modulus breakpoints except you don't have to keep re-enabling the breakpoint in software. You set a start position, the modulus or period between breakpoints, and start your move. Once you hit the start position the hardware takes care of all the rest. With Modulus Breakpoints you can fire breakpoints at about 100 - 150 Hz. With Periodic Breakpoints you can fire breakpoints at 4 MHZ.

thank you very much
It's really helpful
my motion board is NI7344,so I can't use periodically breakpoints
