Power and Controls (Customer) asked a question.
Replacing GS3-43P0 with a GS33-43P0 with speed controlled by input from C-More thru GS-EDRV.
Whats the easiest way to replace a GS3 vfd with a GS33 vfd when the speed is controlled by a C-More thru a GS-EDRV. Currently the drive is turned off and on with a DI. But there is VFD speed feedback and command from a C-More EA9. I looked through the manual and there doesnt seem to be an easy way to control the VFD thru a C-More.
I have used a GS20 and put it into GS2 mode to communicate with GS-EDVR. But this doesnt seem to be an option with the GS33.
I looked into the GS4 vfd but the footprint is too big for my application.
GS-EDRV isn't compatible with GS30 drives. You would either need to use serial, or add a
GS30A-CM-EIP(1 or 2) module to the drive for Ethernet. You'll want to use Modbus protocol in the C-more and specify, in the drive, who controls the freq source. (P00.20 or P00.30).
