Coordinated Control

Aerotech’s control technologies can coordinate and synchronize up to 32 axes of motion of any motion technology to sub-microsecond servo-loop synchronization and sub-millisecond path trajectories. This tight synchronization between all motion axes results in higher precision processing and faster process throughput. Examples of Aerotech controller features that enable coordination and synchronization are:

Using the A3200 ROTATION Command for Five Axis Systems

The ROTATION command in the Automation 3200 (A3200) implements a rotation matrix operation. The function can be used to transform coordinates on mechanical actuators that include rotary motion. Multiple ROTATION commands can be configured to work with systems that have more than one rotary axis. A five‐axis system consisting of two rotary axes and three…

Motion Control with Precision Noncontact Displacement Sensors

Introduction Noncontact displacement sensors are used in measurement applications where surfaces or processes do not allow contact and demand high precision. Capacitive, confocal, eddy-current and laser triangulation sensors have proven themselves in applications that incorporate motion systems. Noncontact sensors are available in many different versions. However, sensor range decreases significantly as the required precision increases.…

Customized Relationships and Coordinated Motion with AXISSTATUSFAST

Many applications require custom coordinated relationships between a system parameter or ancillary motion equipment and the motion of the primary machine mechanics. Likewise it is common to need custom kinematic transformations between a virtual programming coordinate frame and that of the real mechanics. Aerotech’s AXISSTATUSFAST command is an ideal tool to program these relationships and…

Automation1 Servo Drives Improve In-Position Stability

When it comes to characterizing precision mechatronic systems, a meaningful system performance test is the measurement of in-position stability or in-position jitter. In this test, the axis is commanded to hold a target position and the small motion of the mechanical positioning axis is measured. Many applications require nanometer-level positioning and little-to-no motion when commanded…

Maximizing Optical Alignment Precision by Choosing the Correct Positioning Architecture

Advancements in silicon photonics and micro-optic technologies are driving automated alignment tolerances down to nanometer levels. Misalignment between optical components in today’s photonic devices directly impacts the quality of light transmission, and only a few micrometers of misalignment can result in final device power losses of 50% or more (Figure 1). Photonic device manufacturers are…
