Gentlemen, I have 3 motors with gearboxes on all three of them.
All 3 motors have diffrent RPM at 60 Hz at the output shaft, and all need to sync up with one speed pot.
Al three motors would be driven by a seperate VFD(Ab PF 4)
An existing SLC 5/05 can be used to write logic and a 8 chanell 4-20 mA output card for the speed signal from PLC to VFD.
Any Idea how to get this going??? I bet I have to know the Rpm of each motor at 60 HZ. Please help me out with writing logic for this set up.![Er... what? o_O o_O](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
