ABB ACH580 Variable Frequency Drive Dual feedback input for PID control

Good day. This ABB video on the ACH580, shares the setting up of a pid loop which has two feedback sensors. The control of the loop may be a math function of the two feedback signals. This may be realized on stairwell pressurization applications. Please call Borie Davis Inc. at 770-242-0650 and ask for Brad Templeton or David O'Dell, our two VFD specialists. Either of them would be happy to help you with any questions concerning this video.
