Hi guys,
I'm using ML1400 & NC01 to control Powerflex 4M. But I cannot control to start the VFD neither control the speed ! I may ask for instruction or somebody plz point out where did I miss a step :
RSLogix conf: Channel 0: RTU Master / 9600 / Non shaking (485 networking) / data bit 8 / 1 stop bit
Drive: I set up parameters for Power Flex 4M like manual says:
P106=5 / P108=5 / C302 = 3 (9600) / C306 = 0
about C303, I set 100 / then I set 1 / nothing happen
My question is : how come I know ML1400 recognize the drive ? Can we check ? (in this case is that ML1400 is default node 0, drive PW4M node 1 so the C303 should be set = 1)
I wrote the code like the one instruction online (the one with 4 steps), observed the MG9 and see no thing (no Enable, no Done, no Error on instruction symbol)
My first MG is : MG9:0 with modbus command = 6 (write single) / data table address N14:2 (=0) / size element 1 / address 8193 / slave node = 100 or 1 proportional to C303 I set.
---> nothing happen, drive does not start !!???
What did I do wrong ??
Thanks
