Hello,
I am looking to upgrade some controls and logic on one of our pieces of equipment in our manufacturing plant. I need to be able to force an Allen Bradley VFD into a low frequency run condition with a single output from a SLC 500 rack.
The VFD we are using is an AB PowerFlex 523, 3 Phase 480 Volts, 3 HP. Currently the control for frequency is from a pot switch on the operator panel and the wires from that pot run directly to the VFD to control the motor speed.
The jumpers are set as follows:
Analog IN = 0-10V
Analog OUT = 0-10V
Digital IN = SRC
DigInTermBlk05Sel = Digital Input
So to reiterate, the outcome I need is to be able to bypass the control from the pot with an output from my SLC 500 rack (120V) to force the VFD to run at a predetermined frequency.
Thank you for your help in advance.
