ctrlX PLC Motion Interface how to get Axis in reference bit?

[Open]

Hi Community,

I have setup Motion app. Indradrive in SoE.

I want to get the drive axis in reference bit.

When i try Admin.SetAbsRefDone it is for Admin.SetAbsRef done feedback. 

Are there a bit for axis in reference bit i can use?

Warmest regards,

Hello,
I could not reproduce your described behaviour.
Based on 1.20 version :
- core status in Operation.
- ctrlXDriveEngineering used to delete the Ref-status
- check within the Datalayer the cmd and it works form Motion-app side:

- Used the axis-interface

Please verify that the motion is in operational and without failure blocking the command. 
Check ist the araxisctrl_gb.... SetAbsMass gets a rising edge.

Please return with your result.

Bye

Hi @CodeWasi ,

Thank you for your reply!

Setting absolute reference is working. However i want to read the Axis in reference bit in ctrlX PLC using the motion library is it possible else are there any other ways to achieve it?

Hi Open,
sorry i did not realisze the lag.
in 1.20 version the "homed" info is not yet supported. Since 2.x version the homed bit is not supported like expected - since the it is updated during PowerOn on the axis.
I recommend to place the S403 info into the cyclic telegram and check this inside the PLC by realtime-add.

Closing with the positive info that malfunction is placed as fixed soon.

Thanks

As it seems you are using version 1.20 of the ctrlX OS. In this version you need to add the axis in reference bit (S-0-0403 bit 0) to the cyclic data to have it available in the ctrlX CORE and read it e.g. via the data layer realtime node in the PLC.

From version 2.6 on the information can be found in the CXA_MotionInterface: arAxisStatus_gb[1].Data.DeviceStatus.Homed
