Epos initialisation

[david.bsdr]

Hello,

   I'm trying to enable an epos2 motor driver with labview visa but I can't find the right command to send. I tried the "1103 6040 0000 000F E8F2" hexadecimal command but that doesn't work. I think something is wrong with my OpCode but I can't figure out what it is. Could you help me please

Thank you in advance,

Post some code.

Changes are you're sending ASCII data, while you should be sending binary data. But that's just a guess... Is the string set to hex display when you see that data? It should be.

Hi,

there is a wonderful set of LabVIEW VIs for the EPOS2 Positioning Controller on the Maxon Motor Website.

I used it some month ago. Very nice!

Regards

Kay

i send hexadecimal data and that works fine with the "1001 2003 0201 A888" code (it's an example given in the documentation), so I guess my code i good. I think I should translate the binary data into hexadecimal data.

I Know it, but it doesn't work with the cRIO and I can't buy a can open module.

Most things look OK in this VI. I'd make it a lot smaller, more compact. I'd also show the string constant's display style, as you're mixing hex and normal string displays. 

It doesn't show the actual Command you're sending.

I am no epos expert, first time I heard from it, but I'd say the protocol most likely sends 4 words for each command. Your command sends 5 words. Probably the data is a flattened U\I32? You'll need to change it to a U\I16.
