Wiring of CL stepper alarm to estop

[mr_cg]

Hello,
i have AXBB-E motion controller and i want to connect JMC iHSS60 Closed Loop Stepper.
The output connection for the pulse (PUL), direction (DIR) and enable (ENA) signal are clear to me.

JMC Manual:

JMC manual

AXBB Manual:

I would like to use the regular estop input and wire them in row with my estop-switches (normally closed switches).
But for this i do not know how the wiring must be done.
How to connect the arrive position (PED) and alarm output (ALM) in row with the estop-switches to the input from the AXBB-E motion controller?

Thanks for your help!

Any possiblity to get an answer from cncdrive on this topic?
More and more people are using CL stepper and all of them will run into this question how to handle the alarms in UCCNC.
In AXBB-E documentation only traditional stepper are handled and it would be good to add the alarm handling for CL stepper as well.

You can connect normally closed switches in series, just like the limit switches on the drawing in the AXBB-E manual. It does not matter if they are e-stop or limit or whatever.

You can connect your PED and ALM outputs from your drive just like on the drawing in the AXBB-E manual under point 9.3.1.
These switches in your drive are NPN outputs just like what the drawing shows in the AXBB-E manual.

Then you can for example setup an input trigger in the UCCNC for that input pin, you can attach the input trigger to e-stop or stop function of the UCCNC or what you like to do when the input activates.

Also, you can use the FaultSignals plugin which was released in 1.2111. If your driver clears the alarm signal with some delay then you cannot use an input trigger to e-stop, because the delay on the alarm signal may prevent reset from clearing. In the FaultSignals plugin you can set a start delay when the incoming fault signal is ignored.

Thanks to you both. That's really good and useful ansers.
Will consider this two options!

I am also trying to work out how to connect my ALM outputs from my drive to the AXBB-E. I am looking at diagram 9.3.1 and see it is using the 24v circuit, however the wiring diagram for the AXBB-E shows the steppers using 5v for step and direction. Can I simply use the 5v instead?

Relative old thread, but I'll reply anyway as I found this thread while trying to look a solution the the same challenge.

I found a solution to at least to HBS57 closed loop drives. The solution is quite well described in here: https://youtu.be/SvfGTA-aA5k. The trick is to access the CL drive firmware. The software to do that is found at Longs motors service https://www.longs-motor.com/service/. Download the "Closed-loop debugging software", connect to the drive, and opposed to the video, I needed to change the default alarm-level from 1 to 0 to get it working. Note, you need to power down the HBS57 CL drive, and power it up again to get the change downloaded to the drive.

Do that to all of you CL drives, and then daisy chain the connections:
+24V to E-stop positive input (e.g. port 2, input I4+ of the AXBB-E)
x-drive ALM+ to E-stop input (e.g. port 2, input I4- of the AXBB-E)
x-drive ALM- to y-drive ALM+
y-drive ALM+ to z-drive ALM-
z-drive ALM- to emergency stop pin 1
emergency stop pin 2 to zero of 24V (ground)

This did the trick for me to get the CL drive fault conditions to the same port as the other e-stops (emergency stop and all axis NC limit switches)
