Help,Leadshine DM556 open-loop stepper config

Hi,everyone,I'm a new diving to ethercat ,I want to config a machine using ethercat with 3 leadshine DM556 open-loop stepper. Is there anyone be very kind to offer me a sample code(including .ini,.hal,.xml stuffs) or link which can make the open-loop stepper works .Appreciate for any comments ,thanks

HI
To use the DM556 open loop I think you need an Ethercat controller,
I know the FR400, there are probably other devices, I don't know.
On the manufacturer's website you can download a working configuration for LinuxCNC.

I'm working on a retrofit on the electronics of a small old machining center

 

the FR400 drives MOONS' SR4plus and DMA860S steppers, with EasyIO as in/out,
the mini center has an ATC and several in/outs are needed, otherwise the FR400 is sufficient for a traditional CNC,
everything works perfectly.
Hi

Hi,thank you so much .as what you described,it looks that I still need hardware to support to use the open-loop stepper,such as a ethercat controller .I think you are right .Even if I bought the ethercat controller,I still dont know how to config the specific device.So,to the software part,would you share me a sample code or some resource link that I can used for make the open-loop stepper work? I'll appreciate that,many thanks again !

HI
sorry which EtherCAT controller did you buy?

Hi,according to the attachment file .I guess it's called DM3E-556 ?

HI
sorry but the DM3E-556 communicates directly via EtherCAT with LCNC,
what I said applies to the DM556 which needs an EtherCAT controller to communicate with LCNC
I don't see DM3E-556 among the devices supported by LCNC,
you will need to build an .XML generic to make it work   

Hi，I found some resources link in the following ethercat official doc github.com/linuxcnc-ethercat/linuxcnc-et...leadshine_stepper.md please check it .and I thought it mentioned the leadshine 556 ?

HI
in the link you posted there is a reference to the Leadshine EM3E-556E model,
resembles DM3E-556

With an installation of LCNC, etherCAT and the cia402 component,
as fully described here by Rodw,
you can check if LCNC sees the DM3E-556 the same way

otherwise I think you have to work on the .XML file
here is the DM3E-556

Hi,in the terminal ,while I used "ethercat sl" command ,it did show up connected to DM3E-556 but while I used the control panel such as axis ,it can't control the stepper motor to rotate.I guess the problem may be due to .ini or hal and xml file ,but I dont know how to config it correctly .I looks that it 's much more complex to config the open-loop stepper motor comparing with the servo motor.do you have any workable .ini/.hal/.xml file of the open-loop stepper motor ?

in the terminal ,while I used "ethercat sl" command ,it did show up connected to DM3E-556 but while

Connected in "OP" mode or "SAFEOP"?
LCNC starts?
if it starts in halpin lcec.0. your device with connection pins, are they visible?
