Aerotech Advanced Controls Will Increase Your Machine Performance: Throughput, Accuracy and In-Position Stability
Aerotech’s Harmonic Cancellation algorithm dramatically
reduces positioning errors on systems with periodic trajectory
commands or disturbances. This feature, part of the Dynamic Controls Toolbox , provides an easy-to-use command set and
graphical user interface to enable the algorithm and to extract
the highest possible performance from your investment in a
precision motion control system.
Harmonic Cancellation Benefits:
> Reduce position error on periodic trajectories
> Reject periodic disturbances
> Adapts to magnitude and frequency of error source
> Built in setup wizards
Harmonic Cancellation Applications:
> Machining
> Spindle Control
> Cogging Reduction
> EDM/ECM
> MEMS Sensor Testing
> RΘ Wafer Inspection
|
Iterative Learning Control Benefits:
> Repeating move sequences can be learned and optimized 
> Reduce following error
> Increase dynamic accuracy
> Increase product rates
Iterative Learning Control Applications:
> Stencil Cutting
> Stent Cutting
> Sensor Testing
> Micro-machining |

Enhanced Throughput Module (ETM) Benefits:
> Multi-axis feedforward capability
> Faster settling time
> Increase rate stability
> Increase machine throughput with environmental disturbances creating base motion
> Increase machine throughput when high accelerations cause unwanted tool tip motion
ETM Applications:
> Pick and Place Machines
> Semiconductor Inspection
> Genome Sequencing
|
Directional Gain Scheduling Benefits:
> Decrease settle times
> Increase in-position stability
> Automatically adjusts gain based on error motion during settling
> Increase machine throughput with environmental disturbances creating base motion
Directional Gain Scheduling Applications:
> Any high accuracy machine where stiction/friction increases settling time
|
Gantry Control Benefits:
> Both spars are programmed and commanded as a single axis
> Easy Homing
> Marker offset for high accuracy
> Orthogonality corrections
Gantry Control Modes:
> Current Synchronization
> Position Synchronization
Gantry Control Configurations:
> 2 motors, 2 encoders
> 2 motors, 1 encoder
> 1 motor, 1 encoder |
 Friction Compensation Benefits:
> Reduce settle time
> Reduce errror at direction reversals
> High speed, high accelerations and minimal position error achieved with feedforward additive force or torque
Friction Compensation Applications:
> Any high accuracy machine where motion is constantly reversing direction |
Position Synchronized Output (PSO) Benefits:
- Increased throughput
- Higher accuracy
- 1, 2 or 3 axis PSO
- Configurable command pulse train
Use to Trigger:
- Laser firing
- Camera capture
- Data acquisition
- Nondestructive test triggering
Aerotech Advantages
- Aerotech's PSO feature coordinates your motion subsystem with laser firing to produce the highest quality parts and minimize cycle time
- Fully configurable to interface with lasers equipped with externally synchronized control, including CO2, YAG, and excimer fiber lasers
- PSO functionality includes several easily programmed operation modes
- When using a fixed frequency laser, this is complicated by the need for constant velocity, severely limiting processing speeds when faced with complicated geometries, Aerotech's PSO solves this problem.
Manufacturing Applications
- Stents
- Hermetic Welding
- Turbine Blade Holes
- Flat-Panel Manufacturing
- Fuel Injector Drilling
- Gray-Scale Marking
- Material Ablation

Laser Marking Nmark SSaM (Synchronous Scanner and Motion)
> Expand scanner field of view without sacrificing effective pixel resolution
> Mark long vectors with one continuous pass
> Draw large-scale graphics without stitching multiple exposures
> Mark on a tube or other irregularly shaped object without manually repositioning
> Industry standard XY2-100 interface supports scanners from multiple vendors
> Single programming environment for both scanner and servo axes minimizes application complexity
> Eliminate angular errors
Scanner programmed with standard RS-274 G code
Wide-Format Bitmaps
By combining a single linear servo axis with a scanner, the Nmark SSaM BroadMark function makes it possible to mark
graphics over the entire travel of the linear stage in one continuous operation. This approach removes overlay errors
that occur when the image is created through a series of adjacent bitmaps.
