Labview Motor Control third party ethercat device configuration issues

[BenGreen]

Hello,

I am having an issue with a third party device- a Dunkermotoren BG75EC. The system runs a PXIE 8840 chassis with a NI 9144 chassis connected to the motor mentioned above. I have got the PXI chassis working with the NI9144 chassis over ethercat but I have been unsuccessful getting the motor to work. I have followed the steps laid out in previous forums about this issue, but after restarting labview post import, deploying the device changes to the ethercat master the scan engine in the PXI chassis fails to change its state from configuration to active.

When checking the online device state it states the device is diconnected.

I have checked that the device is powered and connected correctly. I know there is power and a connection as the device is able to be detected in the target device pannel.

I have contacted Dunkermotoren and they have been unable to help with this issue as their chosen platforms Beckhoff and not LabVIEW.

This is the motor spec : http://www.dunkermotoren.com/en/products/brushless-dc-motors/detail/885750880009/

If anyone can help it would be greatly appreciated.

This particular issue has been fixed by changing the scan engine rate. Originally it was set at 1ms but after changing to 100us we can now successfully change the scan engine mode from Configuration to Active mode.

Now this is resolved, we're seeing an issue where we cannot deploy the axis which is bound to this motor to the PXI as we receive the attached error.

We're currently testing what exactly is causing this deployment error.

Hi Henry,

Can you please attach your LV project here? I can help look into the deploy error.

Hi Yin_W, 

Thanks very much for the offer, I don't currently have access to the project as Ben is running it through his compliance team before they can share it with us. But if he's happy for it to go on here I'll share it straight away too.

Cheers!

Henry
