where is the inhibit output per axis on pci7344/umi7774

The umi7774/pci7344 has in Axis1 control connector, pin 6, "Enable"

is that is the "inhibit output signal" that is in MAX in the Axis configuration tab?

John,

 

the inhibit signal is logically combined with other signals on the UMI. The logic on the UMI outputs the enable signal.

For more information please refer to page 3-11 in the National Instruments UMI-7774/7772 User Manual.

Jochen ,

 

My Boss have a nick name for people who send to here and there and dont provide a simple answer,

he call them "routers"

 

i allready read this page in the UMI manual, its still not clear, otherwise i dont write this post.....

 

What is "Enable" pin 6 ? to where i need to connect it on servo drive?

why this signal is always on?

why when i click "initialize" in MAX nothing happened...

 

 

Thank for answer

 i think that only NI application Engineers know how to work with NI products....

Hi John,

 

wow, you really know, how to keep up people's motivation who try to help you...

Anyway, if you need a specific answer, please post specific questions. From your original question I couldn't tell, what you have read and what not, so I'm sorry, if my first answer didn't meet your expectations.

 

The enable signal on the UMI is an output, that should be connected to a corresponding input on the drive. Please compare the signal compatibility before connecting the pins. Typically drives provide an Enable input, that is used to turn on/off the motor power by an external signal.

As described in the manual, the enable signal toggles depending on several signals. You may need to adjust the polarity switches on the UMI to make the Enable output work according to your needs. E. g. depending on your setup there is a chance that a wrong polarity of the Fault input signal sets the Enable output to a fixed level.

You can test if your Enable signal is working correctly by using 1D-Interactive. Hitting the "Kill" button should assert the signal, "Halt" should reset it again.

 

I hope that helps,

Jochen

Jochen,

 

That was a really good answer!!!  thank you!

 

Specially this lines:

"E. g. depending on your setup there is a chance that a wrong polarity of the Fault input signal sets the Enable output to a fixed level.

that i dont think its relevant, and probably this is what causing my problem,that is why i need you the expert that know on what to look at and help the dummies that do the first steps.

 

by the way, you answer another post of mine 2-3 days ago,

and again that was

 

Finally my friend,  when you earn a Kodus you get a Kudos, when you just a router that transfer links, you just a router.

 

You got a Kudos of this one 🙂   its yet not a solution.. if it works for me, i came back for "solution" you also 😉

 

John
