The ED Series represents a new concept for motion control units, combining cam and motor control technology into a small footprint. This revolutionary concept delivers accuracy and flexible performance in a tightly integrated package. The ED series allows you to program a cam indexer with flexible, stable motion patterns with the same ease of controlling a motor. The package is perfect for benchtop production lines without using excessive drive equipment.
Wide Product Lineup
Available as a stand-alone indexer, or with a choice of factory-mounted stepping motor,
induction motor, or gearmotor.
