Re: Question on remote VFD panel usage

On the FM100 drives there is a header inside which is logic level
RS232/RS485. The drivers are added externally. The drive can be
programed with PC based software and can also be controlled throught
this interface. I have the documentation for the control protocol.
I'm not sure about the MA7200 as I have not used one. Westinghouse is
pretty helpfull. I'm sure you can get the information you need from
them if you call them.
