Does anyone have any knowledge on the DGFC 6KCV300DGF card that was installed on some AV300 GE drive systems? This is a digital general function card. Thanks.
"The optional Digital General Function Card (DGF) is mounted on the AV300i drives
for special functions such as winder/unwinder control, positioning, etc. It connects
with the drive regulation card via the connector for an optional card. The connection
with the drive also provides the power supply for the DGF.
The communication between the two cards uses a 2Kbytes dual-port ram (DPRAM).
The 6KCV301DGF card is based on an Intel 80C386EX-25 with a numerical processor
80C387SX-25.
The standard user communication on the card is RS-485 serial link.
It is possible to mount an option module with CAN controller for DeviceNet
communication.
It is also possible to read and write DGF parameters using all the drive communications
[serial link, local keypad and an additional optional communication card (e.g. GENIUS,
INTERBUS-S or PROFIBUS-DP)]. All these communications use the drive
microprocessor and DPRAM. ......" End Quote
Thank you for your reply. You are correct in everything you said. But, We had a DGFC card fail, which is no big issue. We replaced the card. You can access the DGFC using a DOS based program called HIBS. We can also do a save parameters on the new card by using the "W" command and then naming a file to save it to. But, we have 13 drives total connected through the LAN card mounted on the DGFC. When trying to upload parameters from any of the other 12 drives usuing the same command we get 3 to 4 lines and it stops there and goes no further in the upload. We need to know how or what parameter needs to be change to accomplish this. In this setup we have 1 drive with the identical parameters for the DGFC, which needs to be loaded for proper winder control.
