UCCNC ETH300/UB1 Servo Alarm Setup

[cncdrive]

Simplifying it to the UCCNC and neglecting what board it is, it is a single input pin for the UC300ETH module and for the UCCNC.
So, if that pin is configured as e-stop input and if it triggers then the UC300ETH motion controller triggers the e-stop logic of the software.

Because it is a single input pin in the UCCNC it can be easily seen if the problem is in the UCCNC or on the board, because if the input pin triggers (input LED on diagnostics window goes to active state of configured e-stop input) and if the software does not trigger the input then the issue is in the UCCNC otherwise if the input pin trigger triggers the e-stop then the issue is with the board or with the wiring.

And by asking CNCroom I thought about you emailing him, would be probably faster...

I forgot to mention in my post that the signal IS in fact getting to UCCNC from all inputs i102-i106. Only i102 is triggering the Estop while others get acknowledged by both UB1 and the software but don't trigger an Estop.

How are you triggering an estop from i102, as there are no terminals on the UB-1 for i102?

The OSSD terminal is an output activated by the safety circuit.

Hi Gerry,

The manual sais that the OSSD circuit has a feedback on port1 pin2, so you can connect it as e-stop. Also, I have a profile from a user who connects the OSSD feedback to e-stop. It has no X102 terminal, because the OSSD output is connected internally to port1 pin2. On the second picture I marked the input pin.

@ger21: @dezsoe is absolutely correct.
@dezsoe: do you have this functionality fully working on that profile?

[dezsoe]

No. Sorry, I don't have this card, I can only check the documents and some profiles. But, as I see, the developer answered you CNCZone, so you'll get the answer.

[ger21]

Yes, I know that you assign the estop to port1 pin 2.
I'm just confused about how he has it working in one profile.

Does the LED on the UB1 at the OSSD terminal toggle on and off?

I hope this video can save me from typing a whole lot of words. You already know that I have the solder-bridges established as per the docs. Please take a look at the video and advise.

[ger21]

I don't see the OSSD output LED lighting up when you active the input with the sensor. That would mean that your safety circuit is not working?
Also, one you activate the input one time, you would need to reset the safety circuit. I don't see you doing that?

[pupdogg]

@ger21: Yes, all I was expecting to see was that the RESET is triggered but it's not. I can understand if it was my soldering job that could've caused problems but for this example, I'm using i103 which is soldered/tested at the factory. As per @weerasak's response on CNCZone (https://www.cnczone.com/forums/uccnc-control-software/339798-cnc-4.html#post2194614), I thought he was saying that RESET is only triggered when the cycle is running and I thought maybe that might be my issue...so I dediced to make this video while the cycle was running. The reason this issue is very important for me is becuase I just ended up scrapping a $150 PVC sheet because Lost Phase fault on my Y axis servo-drives never triggered Estop. You can see a big gouge in the attached decorative panel as a result of this error.

[ger21]

The safety circuit should work without UCCNC even running. Actually, I think I described it wrong before.

The OSSD LED should be always on, and go out when the inputs are triggered.

Do you have a reset button to reset the safety circuit? It could be that you need to reset the safety circuit?

I'm not at home all week, so I can't look at my UB-1 or do any testing.
