5i25 + 7i85s +....

Hello,

I´m a happy user of a combo 5i25 + 7i85s for control 3 motors with 3 encoders.

I need extra inputs and outputs now, and I don´t know which card should I add to my combo and how to do it.

I need 6 digital extra inputs for limit switches, but some extra inputs and outputs are welcome.

I need too an analogue output that can handle a 0 -10 V frequency converter.

Which card do you recommend me and how can I add it to my combo??

Thank you very much!!

The easy way to do this would be with a smart-serial card connected to the RS485 header on the 7i85s.
Note that there are 17 perfectly usable 5V TTL GPIO pins on the second header of the 5i25, though.

I need too an analogue output that can handle a 0 -10 V frequency converter.

Do you mean Variable frequency Drive or Motor Inverter when you say "frequency converter" ?

You could consider using the Spin1x. store.mesanet.com/index.php?route=produc...id=205&search=spinx1

Hi Andy, sorry for the delay answering.

You helped me a lot when i made my system few years ago! Thank you again

When you say smart-serial card you mean a mesa card or can be a generic card?

I mean Variable Frequency Drive, is the one i use to control the speed of the electro-spindle of the machine. My english is very bad i dont know if it will be the word i want to say so I attach you a file with what i mean.

Thank you!

I mean of these, which connect to SERIAL0 on the 7i85S.

Hi again,

This is my Variable Frequency Drive:

I´ve been searching in the page for a daughter card that can solve my problem.

I dont see any single card that can do the two things i need to do ( 6 digital inputs for limit switches and 0-10 V analogue output for my Jx inverter). Nowadays my setup is 5i25 + 7i85s linked by a paralel port cable, can i add to this combo a 7i83 and a 7i84 to achieve my needs?

Thank you!!

You could consider modbus control.

Though this might be more work than it is worth as I don't think there is a specific HAL driver for that drive.

If you can find a PWM output spare on the 7i85 then you could use the Mesa Spin1X.
