5i25, 7i77 problem

thank you very much friends ....

I know it's something simple, but for me it is very valuable all this information.


forward in my project.

New Here bothering.

I have three concerns.

1. Looking at the HAL that Rick (LAIR82) published in a thread,

www.linuxcnc.org/media/kunena/attachments/legacy/files/rick.txt

I realize that the external output signal and external signal input, place the vast majority of "net" prepending #. this would indicate that only a comment?
of the machine and mine are like a lot. but that just confuses me see connections no comments.


2. thanks to you I could see the inputs and outputs of the "7i64" but are different from the "7i77" I look like this:

net min-x <= hm2_5i25.0.7i64.0.2.digin.02.in

digin not nothing wrong?


3. I want to try the servomotors and the "DC spindle motor" without connecting anything else yet, or home sensor, limit switch, nothing more. that's possible?
bone without linuxcnc throw me any error?

thanks in advance.

Looks fine except all the logical control signals are 120VAC input.
Its pretty likely that these are already connected to a 2IO4B rack so the 24VDC-->120VAC level shift may already be done for you.

This, and the state machine way the control inputs work probably means
you need to use 7I77 or 7I64 outputs for the 24 V signals that drive the
2IO4B that drives the 4 spindle control signals (manual page 21)

Also note figure 4.8 on page 57 This should be close to how it is wired now
So the first step on the spindle interfacing is tracing whats already there
(or better yet reading if you have the machine manual)

You want to retain as much of the original safety and interlock wiring as possible

a 50 HP spindle can kill you in milliseconds

Peter,

greetings,

Friend, I am applying 120VAC at terminals 33, 44, and 32, but I notice that the motor runs, but rotates with difficulty. The question should not only operate the contactor M, hoping that 326 and 157 into action? or am I wrong?

any advice helps.

thanks

There are three logical inputs (ignoring jog)

32 start
33 stop
44 coast

These are all momentary inputs as the drive state is latched.
Only one should be asserted at a time, and removed after its applied
so if you apply 120VAC to start (32) and then remove it
the drive should be in run state and respond to analog speed commands on pin 326/157
