We're considering a rotary table capable of two operation modes: 1) rotating at speeds up to 3 rpm and 2) positioning with precision of 60 arcseconds. That is 21600 positions per turn and 1080 positions per second at max speed. Also, during rotation, the current position must be recorded upon signal from an ultrasonic scanner (which is a blackbox at the moment) to be fetched by a computer later.
This kind of control is new to our company. I think it could be accomplished with a PLC that has high speed inputs and an optical incremental rotary encoder attached to the VFD motor shaft. Am I right or is there a better approach? Particular products? Any suggestions at all?
Thank you!
