Per axis High speed capture using UMI-7774

[M0Reng]

Hi,

I want to use High speed capture on each Axis of my pci-7344 motion controller.

i'm using UMI-7774 and evrything is wired properly to the servo drive etc..

i read the umi-7774 manual, but i didnt see anything about the High-seed capture trigger.

How i can use the High-Speed capture signal for Axis1 ?

what are the wiring needed in the umi-7774 to use this signal?

Page 3-25 in the manual:  "The UMI-7774/7772 has a single 15-pin D-SUB connector you can use for

trigger input and breakpoint output wiring. This connector provides access

to four trigger inputs and four breakpoint outputs. "

is the TRIGGER/BREAKPOINT  connector in the Global connectors of the UMI has this signals for each axis?    

Thanks

Mor,

the input signals for HSC need to be connected to the trigger inputs on the Trigger/Breakpoint connector.The pinout can be found in table 3-8 on page 3-26. Trigger 1 belongs to axis 1, trigger 2 to axis 2 and so on.

I hope this helps,

Dear Jochen,

Thank you for your reply.

Now i'm sure about how to wire the trigger for Axis1.

I have anpther question, i hope you can help also:

I  want to use Modulus Breakpoint and route the breakpoint signals to RTSI,

But , The First Breakpoint need to be route to RTSI_0 and all other breakpoints after that need to be route to RTSI_1

 How can i do that ?    i see in the motion examples only example that shows how to route the breakpoint signal to one RTSI line.

Thanks

Mor

Mor,

I don't think it's possible to route multiple signals to the same RTSI line because this would mean that while one signal is in the High state, other signals pull the same line to the Low state. I think you will have to use some external logic circuitry to OR the breakpoint signals.

OK,  Thank you very much for your quick answer.
