I'm quoting on a job for a conveyor line.
We have 17 sections of 20' conveyor, approx 1/2HP motor/drive on each.
Customer wants to be able to vary the speed of the line (one speed for the whole line).
Because of the distances, we are contemplating putting a JB and drive at each motor (350' from main panel to last conveyor).
Q: Has anyone used one drive sourcing multiple motors?
Q: Is there such thing as a 1/2HP AC drive with a built-in starter/overload?
Q: Is there a drive as above, with a built-in VFD?
I've not investigated a cheap stepper or servo, but my gut tells me it still will not be cost-effective.
Electrician wanted to get drives with a card reader or similar way to clone one drive to the other 16 - for initial setup but mainly to vary the speed. I told him to pass on that; we'll use analog.
Q: Anyone have any qualms about sending a 4-20mA signal, 350', with 17 taps?
