Resolution:
+/- Speed Around a Reference is a way to adjust the motor speed above or below a given Speed 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.
