Fast response positioning sub-system is
economical
Positioning sub-systems provide a combination of economy, speed and controllability to accelerate production cycles in modern automation, packaging, material handling, and automated assembly.
Copley Controls offers a cost-competitive sub-system for fast response position control applications The sub-system consists of a direct drive ServoTube actuator, driven by Copley's high power density Micro Xenus controller

A new short form catalogue represents a large range of linear motion components and accessories available on a 'one-stop-shop' basis.
Innovative feedback ensures precise positioning
Integrating an innovative feedback mechanism for precise positional measurement, linear servomotor drives deliver exceptional reliability and robustness along with significant cost savings.
Actuator and controller create an out-of-the-box drop-in replacement for ballscrew and pneumatic positioners, bringing benefits of superior controllability, agility and faster machine cycle times.
The matched positioning pair develops velocity to 3.8m/s and peak drive force to 87 lbf.
Significantly, the actuator requires no costly external encoder for position feedback.

Quick and quiet actuators challenge ballscrews
High-powered linear actuator produces 1860N peak force, more than double the force of the existing models and behaves more like a quiet ballscrew actuator, but ten times as fast.
Industrial actuator is a single part device
Rugged, easily installed, and a linear motor, a self-contained simplified linear motion concept uses a moving rod rather than forcer.
ServoTube's patented magnetic circuit enables an integral solid state sensor to provide 12 micron repeatability.
ServoTube actuators are driven directly by the interaction between their permanent-magnet and electrically-energized magnetic fields.
There are no intervening motors, gearing, couplings nor ballscrews to degrade reliability and add inertia.
ServoTube's permanent magnets are sealed into the stainless steel Thrust Rod; its electrical drive coils are encapsulated in the non-moving Forcer.
The actuator's load positioning Thrust Rod travels on long life lubrication free bearings that are built into the Forcer.
The unit has the same form-factor as pneumatic and electric actuators, conforms to international mechanical standards, and is compatible with a wide range of industrial accessories.
Owing to ServoTube's inherent dynamic superiority, plus Micro Xenus' state-of-the-art control, the duo offers a potent and cost-competitive drop in upgrade for conventional actuator mechanisms.
For applications involving side forces, ServoTube actuators are available with bearings that resist lateral loading.
An electromagnetic holding brake is also available to support the load in vertical installations.
Additionally, the actuators meet International IP 67 washdown specifications and are foodsafe.
Micro Xenus controllers provide the extraordinary functionality of Copley's earlier big brother Xenus controllers.
They develop 10A peak output and operate on 120-240V AC.
Micro Xenus controllers drive ServoTube actuators in a wide range of system environments.
Examples include multi-axis CAN/open and DeviceNet control; ASCII and discrete I/O operation, +/-10V position/velocity/torque commands, PWM velocity/torque control, master encoder for gearing and camming, and digital input sequencing for indexer operation.
* Applications - ServoTube/MicroXenus positioning sub-systems provide the combination of economy, speed and controllability needed to accelerate production cycles in modern automation.
Applications include packaging automation, material handling, and automated assembly, among others.
