What is "Speed Around Reference" and how can it be used on the ATV61 or ATV71 drive?
Speed Around Reference
All models and serial numbers
Speed Around Reference is a way the drive can adjust the motor speed above or below a given speed reference. Speed Around Reference allows the drive to vary the motor speed above or below the reference. One application for Speed Around Reference is to run a secondary conveyor belt above or below the speed of a primary conveyor belt with a single speed reference going to both drives. It may be a case where two conveyor belts are feeding a single conveyor. The single conveyor may need to run at a slightly higher speed to keep product moving. See the ATV61 or ATV71 programming manual for details.
