Labview and servo drive / motor control

Hello,

 

I've got a project where I need to control a servo drive (which controls a servo motor) with Labview. The drive is an Emerson Digitax ST indexer drive that has an RJ45 port on it. I can normally connect from this port to my laptop via a USB to serial converter and use the Emerson software for monitoring and motion control, but I would like a more robust system of control using Labview.

 

Can anyone please suggest some idea, as I am very new to Labview. Thanks.

You should be able to use the same USB to serial converter with the LabVIEW VISA library.

 

The RJ45 connector is just a serial port, so you could also wire it into a 9-pin connector and use the RS485 to USB adapter the http://sine.ni.com/nips/cds/view/p/lang/en/nid/12845

 

The alternative is to program the drive to respond to the analog inputs and wire those to a DAQ card.

Thanks chrylarson

 

So I suppose the VISA library enable Labview communication with 3rd party devices?

Yes. VISA is an api for communicating to GPIB, USB, Ethernet, serial, pci, etc.

There are a couple of serial examples that come with LabVIEW. They are the best buy should provide a starting point.

Hello 

I know that this subjet is a little bit old but I wanted to know what was te request or the command you sent to The Emerson Digitax ST connected to the servo motor in order to control it. I used the 9-pin connector and the RS485 to USB adapter. I established the connection but still enable to have informations that I need from the machine. Actually I wanted to have the output current and the servo motor's rotation speed.

I need your help please.
