Hello, So I was asked to turn up the speed on a VFD to allow a carriage to move a little bit faster and avoid getting stuck. Im not sure the exact VFD model but in the PLC logic it seems like there is a tag with the description "SPEED REFERENCE"
I came across an older post on the forum that mentioned the speed reference is 4 characters long for some VFDs and that is similar to what I'm seeing in the program here. the speed reference is set to 5000 and then after reaching a certain point it is slowed down to 2500 or 1250.
Is this the correct tag to change to speed up or down the speed of the VFD?
In the attached image it seems like there is a slow speed, medium and fast speed based on where the carriage is on the track.
appreciate the input.
