I Have two motors, both connected with two different Vfds. First Motor is connected to VFD-E series delta vfd and other to MS-300 delta vfd. I need to sink first motor with the second. I remained successful in getting a variable volt using AFM of the first vfd, and connected AFM and ACM(ground) to AVI and ACM of other VFD. But speed of 2nd motor is not varying with the first one. even after inserting parameters.
Help needed!

What did you find on the OEM technial manual about that "VFD multiple units sync ...."

They are bunch of documents & videos on the WEB that can be useful !

Try to have a good read first on that documents..

And tell us more on the system workd on :



-What communication protocol is used for this application..

-Are you using Modbus comm?? or other support...

We do not know if You may have an correct/incorrect configuration...

So more you add gathering datas, the best we can support..
