If PowerFlex 4 VFD’s are being used, the following parameters need to be set
on each VFD.
1. P36 (start source) = 5 (comm port). If using backup control P36=2 (2
wire).
2. P38 (speed reference) =5 (comm port).If using backup control P38=0
(drive pot).
3. If using backup control, A51 (digital In 1) =6 (comm port). Otherwise
A51=0.
4. PowerFlex 4/40 - A103 (comm data rate) = 5 (38.4k), PowerFlex 400 -
C103 (comm data rate) = 5 (38.4k)
5. PowerFlex 4/40 - A104 (comm node address) = 1-4, PowerFlex 400 -
C104 (comm node address) = 1-4
6. The PLC is programed to control PowerFlex 4 VFD’s at node address
1-4. If pump #1 is a PowerFlex 4 drive, it must be set to node “1”. If
pump #2 is a PowerFlex 4 drive, it must be set to node “2”, and so on
