Hello,

I am pretty new with this servo. Please help. I don’t use Arduino.

Thanks a lot

Hi,

Do you have all the parts necessary for powering and connecting the servo to your computer via a serial/USB port?

If so, all you need to do is implement the serial protocol for the servo in LabView. The protocol and commands are described starting on page 18 of the manual that’s available in the Useful Links section.

You will need to study the details of the protocol, but essentially you will need to send commands to read and write to the registers of the servo to update its configuration and instruct it to move in the ways you would like.

Hope this helps,

Thanks jarcand for your reply.
I was able to test the command on the Herkulex software manager with different rotation angles.
However, when I use VISA in Labview to read in the hex command, it gives the timeout error. I used the "continuous serial write and Read example in labview and use this comand:

FF FF 0C FD 06 92 6C 3C A4 00 00 FD
I double checked the command and it works fine with the Herkulex software.

Do you know what is the possible reason?

Thanks
Sandra

Hi Sandra,

Unfortunately, I’m not familiar with VISA in LabView…
