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!!

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!

Hi again,

This is my Variable Frequency Drive:

industrial.omron.co.uk/en/products/jx

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!!

I prefer having a HAL driver for the card. My knowledge of programing is very low.

About the Mesa Spin 1X:

VOUT is a Analog voltage proportional to the PWM input signal and the Analog reference voltage (5 to 18VDC).

Does this means that the analogue output voltaje is 5-18 V??

I dont mind if i have to buy a second 5i25 card to achieve my needs.

Thank you again.

The SPINX1 is a digital potentiometer replacement, that is,
it takes a fixed voltage (5 to 18V) and generates a
variable voltage that depends on the PWM duty cycle
so if you supplied 12V to the SPINX1 and the PWM input duty
cycle was 50% you would get a 6V output (and 3V for a 25% duty cycle etc)

Most VFDs have a speed control input that's designed to work with a
potentiometer, that is, they have a 10V voltage source, a speed control input,
and a common pin. These can be connected to the SPINX1 and allow
LinuxCNC to control the spindle speed by varying the PWM output duty cycles

My VFD can be managed by a 10 V analogue signal.

So, if i have understood correctly, i need a 10 V power supply connected to the SPINX1. I also need to use a PWM output from Linuxcnc connected to the SPINX1.

How would i do this? Do i have to connect the SPINX1 to the 7i85s?

If this is correct, i can do this and connect to the second connector of the 5i25 a 7i84 daughter card to have the 6 digital inputs for the limit switches, cant i?

Thank you!
