Hello men
Hardware:
1769-L32E (Processor)
1769-IF4XOF2 (Low resolution Analog Input (4 point)/Output (2 point)card)
VFD: PowerFlex 40 - Single-Phase 240 Input Voltage, 3-Phase 240 Output Voltgae)
1HP 3-Phase 240V Motor
Software:
Logix5000
I am stumped. I have never controlled anything via analog output. I am still green so please be patient with me. I am wanting to learn how to control the frequency to my 1 HP motor via hard wired conntection from my analog output point to my VFD control terminal block. I know I can use ethernet but I want to use a hard wire connection.
What I have done thus far...
I have connected (shielded cable)the red wire to my (ANLG Com) on the Analog Module to the (ANLG Com) to my VFD. I have connected the black wire to the (I out 0+) terminal on the Analog Module to the (4-20mA input) terminal on the VFD.
The switch inside the VFD has been set to 0-20mA
I can turn the VFD on and off via control relay so that part is done.
All my VFD codes are programmed properly in the VFD in order to receive and execute analog inputs.
What do I need to do from a programming standpoint is to control frequency. I need some help with understanding the output data file and how to use it for what I want it to do.
Thanks guys for your help!
