Accu-Set Syncs Mutiple Motors Economically-Image

The Accu-Set Digital Closed-Loop Interface from Dart Controls is a variable speed motor control accessory for use with conventional AC, DC or Brushless DC drives regardless of brand or HP rating. It provides the user a fully configurable LED display of set speed, as well as pulse pickup feedback to close the motor loop for precise speed regulation. Sensors such as the Dart Hall-effect PU-E Series pickup send pulses back to the Accu-Set from the controlled shaft for comparison to the desired set speed.

Most AC and DC drives come from the factory configured to run in a single, open loop mode. Many drive applications require some sort of speed change in proportion to a reference. Mixing and blending applications may require two or more motors to run in proportion to a master reference. The Accu-Set adds this capability to any drive that has a potentiometer or voltage follower input for set speed.

Target speeds are displayed directly in RPM, FPM, GPM; process time, ratio, or any other engineering unit of measure. Front-panel access allows factory or field programming of the the Accu-Set to the exact configuration needed for each application; maximimum and minimum set-points, decimal points or colons, operating mode (Master, Time or Ratio), and math functions to accomodate motor gear ratios.

The Accu-Set is simple to operate...Just set the desired rate, ratio, or time in the large 1/2 inch LED display one digit at a time, or fast sweep. The Accu-Set helps motor loops overcome line voltage variation, load changes and other factors that make open loop systems less repeatable.
