LEFS Electric Actuator, High Performance Slider, Ball Screw Drive

LEFS*F is a high performance version of the standard slider, equipped with a direct mounted, inline motor.  Typical load capacities have increased 9-50%.  Cycle time is dramatically reduced by a combination of higher maximum speed and acceleration/deceleration.  Note that maximum speed gains are primarily in the 50-400mm stroke range, ranging from 5-36% faster depending on motor size and ballscrew pitch.  A new high performance step motor controller, the JXC*H, pairs with the LEFS*F actuator.  Actuator dimensions and mounting are identical to the standard LEFS, allowing an upgrade for existing equipment.  I/O and actuator cables are also identical to the standard LEFS.
