PowerFlex70 via CNET

curlyandshemp · May 19, 2012

for the life of me I cannot remember which parameters to configure in a PF70 to control the drive speed and start/stop via CNET. I have 3 drives all on CNET and all configured and scheduled properly. The reference manual is not very straight forward on how the drive should be controlled via DPI Port 5 the Comm20C module.
I had to leave the drives configured using Digital In 2 as RUN and speed reference via Preset 7 in order to control the drives.

Can anyone help me out please?

You need to set PAR 90 to DPI Port 5 on PF70
You need to enable Logic Mask PAR 276 DPI Port 5 bit 5 on PF70
Set PAR 361 to 366 to “Not Used” on PF70
Go to your RsLogix5000 Program, then go to controller program scoped tags and check the VFD “Add on Profile”.
Logic Command Word bit 0 = stop, bit 1 = start
