text: <s>[INST] Looking for an AC Vector Drive Recommendation Hi, I am wondering if Rockwell has an AC vector drive that would meet the following requirements: (1) Power 220 VAC 3 phase (2) Capable of closed loop speed control using feedback in the form of a frequency (from and encoder or ring-kit w/ open-collector speed sensor). (3) Ability to display measured speed (from speed sensor) and to allow set point entry in scaled engineering units of my choice rather than Hz or even motor RPM. (This would be for a web handling machine, so I would like to be enter speed set points in ft/min and have actual speed also displayed in ft/min). This will require the drive to allow me to enter a scale factor to relate feedback from the speed sensor to ft/min taking into account my gear reductions, roll diameters, etc. (4) Allow set point entry using a built-in interface on the drive itself (keypad w/ LED display) rather than requiring the use of an HMI (5) Ability to follow a master speed reference that would be supplied to the drive as a frequency. Any advice will be greatly appreciated. Thanks in advance, Paul [/INST] Please explore TechNote 581453 \\n </s>
