Hi All,
I am trying to Start/Stop & frequency control Parker AC10 drive over RS485. I am using USB - RS485 converter. From what I have done so far, I think the issue is either my understanding of commands or the converter cable is not doing it properly.
I really appreciate if someone can give help on this.

Hi,
I can't see any error in your post. Some manufacturers of RS-485 devices reverse the data names. So you can try to swap the data wires.
EDIT:
I never use the MAX I/O panel Just tried it. How do you enter hex data ??
Do you use LabVIEW ??

Hi Kees,
thanks for your response.
I use MAX because it seems more user friendly than PuTTY or any other termianal apps.
Also it has the NI I/O trace where you can monitor raw data at the port. If you go to second icon on top "Input/Output", you can type in the second box from top named "Select or Enter Command"
I tried swapping the wires but no luck.

Still not clear for me how you enter HEX data. Will give it a try one if the coming days.
Do you use LABVIEW ?
