Good afternoon, I am making the connection of the limit switches, I have a blocked port, which corresponds to IN1, and in the literature that I have I cannot find how to unlock it, in the images, attached, in Capture.JGP the open led appears NOT with a bar at the bottom, I am following the plan with the date number 180115.
I am attaching the photos and the report file.
I appreciate your help
Sincerely,
Oswaldo

Buenas tardes, estoy haciendo la conexión de los interruptores final de carrera, tengo un puerto bloqueado, que corresponde al IN1, y en la literatura que tengo no encuentro como desbloquearlo, en las imágenes, adjuntas, en la Captura.JGP aparece el led abierto NO con una barra en la parte inferior, estoy siguiendo el plano con el número de Date 180115.
Estoy adjuntando las fotos y el archivo de reporte.
Agradezco su ayuda
Atentamente,

Oswaldo,

looks like you are misinterpreting the colors of the Alt-I LED colors. An input can be configured as Normally Closed (NC) or Normally Open (NO).

By default an Input is configured as NO. If a LED has a bar on top of it, that means the Input is configured as NC. If an Input has the configured status, the LED will be Green. That means a NO configured Input is Green when the Input is open and turns Red when it closes. A NC configured Input is Green when it's closed and Red when it's open.

When you configure an Input, you select NO or NC based on the status that your limit switch has when it's NOT triggered,

To change from normally open (red) to normally closed (green) in the Wizard, click on the input number and it will change

Tom with the literature he sent me, I found the key combination to invert the entry. Thank you.

-swissi thanks for your support and it really is not a confusion, what I have is that I have been making changes for several days and until last night I realized that I had inverted the input port with the Ctrl alt f keys that was the command that did not had.

Marty thanks for your support.

Oswaldo

Tom con la literatura que me envió, encontré la combinación de teclas para invertir la entrada. gracias.

-swissi gracias por su apoyo y realmente no es una confusión, que tengo es que llevo varios días haciendo cambios y hasta ayer por la noche me di cuenta que tenia invertido el puerto de entrada con las teclas Ctrl alt f ese era el comando que no tenia.

Marty gracias por su apoyo.

Oswaldo

Oswaldo,

Yeah, the selection square around the LED 1 on your screenshot made it difficult to see that the LED does have a bar on the bottom which does indicate that the Input has been forced to be inverted from it’s configuration.

Sorry I missed that and glad you found the solution.

the doubts I have are the following after the description of the photos:
-The following box in the home image 1 is being presented to me.
-This is how the PLC home image 2 is configured
- Home image 3 shows the DMM DYN2 configuration
- Image home 4 shows the configuration of the inputs
- Image home5 shows the axis configuration
-Image home 6 shows the settings for home program
As I could see in image 1 it appears that the limit switches are all locked.
Figure 2 shows the signal for input 1 as closed and input 2 as open. I do not understand why?
In image 4 is the configuration of the inputs.
In image 5 is the configuration of the axes.
In image 6 is the HOME setting as such.
What I do not understand is why when I go to home it is blocked as it appears in the box of the image 1
When I see the status of the PLC the signals one is closed and the other is open.
And therefore I have not been able to configure HOME.
I appreciate your help.

las dudas que tengo son las siguientes después de la descripción de las fotos:
-Se me está presentando el siguiente recuadro en la imagen home 1.
-Así está configurado el PLC imagen home 2
- La imagen home 3 muestra la configuración DMM DYN2
- Imagen home 4 muestra la configuración de las entradas
- Imagen home5 muestra la configuración de ejes
-Imagen home 6 muestra la configuración para home programa
Como pude notar en la imagen 1 aparece que los finales de carrera esta bloqueados todos.
en la imagen 2 aparece la señal de la entrada 1 como cerrada y la entrada 2 como abierta. no entiendo por qué?
En la imagen 4 es la configuración de las entradas.
En la imagen 5 es la configuración de los ejes.
En la imagen 6 es la configuración de HOME como tal.
LO que no entiendo es por qué cuando voy a home se bloquea como aparece en el recuadro de la imagen 1
cuando veo el estado del PLC las señales una está cerrada y la otra está abierta.
Y por lo tanto no he podido configurar el HOME.
Les agradezco su ayuda.

Oswaldo,

Without seeing pictures of all the home and limit switches (type of switch and how they are physically connected to Acorn) we can only guess what’s going on here.

My first question is: Why are you using home and limit switches? Especially with closed loop drivers, there’s absolutely no need to have limit switches. Just use home switches and set the soft limits. Works perfectly.

If you use HomeAll with NC type home switches, you need to connect them in series. If you have multiple home switches in series on Input 1 and the LED in CNC12 is red, you only know that one of the switches is tripped but you can’t really tell which one it is without looking at the LEDs on the switches.

Enter your soft limits in the Wizard even if you do use separate limit switches.

That’s all I can say without seeing details mentioned above.

The switches are NPN NO, and they are connected in series,
Thanks for your help.
I will be reporting
Oswaldo

-swissi

Los interruptores son NPN NO, y las están conectados en serie,
Gracias por su ayuda.
Le estaré informando
Oswaldo

Oswaldo,

if the switches are indeed of type NO as you say, why did you configure them as NC? Also you can't connect NO type switches in series, you need to connect them in parallel.

There are two major problems using NO type switches. The first problem is that CNC12 can't tell if your switch is working or not.If there are any connectivity issues with that switch, you won't know until the machine crashes when the switch fails to close the input. The second problem is that NO Inputs are much more likely being falsely triggered by electrical interference than NC type inputs.
