Greetings,

Are there any manufacturers that produce small DC VFD's with Ethernet I/P? Such as the drive in the link below, but with Ethernet I/P.

Tia,

Try These they may have what you want

to be clear DC drive (Direct Current) and VFD (Variable Frequency Drive) are not the same

Bardac is the only one I know of with Ethernet, but I don't think it's Ethernet/IP protocol, it's their own Ethernet connectivity system. You could ask them though.


On a couple of projects I've been involved with, we changed to using Stepper motors because there are several choices on stepper drives that support E/IP.

Control Techniques to DC Drives with Ethernet/IP as an option, but they are designed for slightly bigger motors. Is there any specific reason for using Ethernet/IP as opposed to getting a small controller from someone like Maxon and controlling it using an analog signal?

Looks like Nidec's control techniques is your answer.
Ethernet IP module

For smaller sized motors Beckhoff has some io slice type DC drives that you could attach to an ethernet i/p header

Honestly, by the time you add a new drive and Ethernet module for an existing DC motor this small, you might as well change it to AC, unless it's a special motor or something...

If I was stuck using a DC motor and drive, and had to interface it with Ethernet, I'd just add a Click with an analog output to the existing drive.

Otherwise, I'd use a small AC drive with E-I/P and a new AC motor...
