Automation1 Control Systems Demonstrate Significantly Improved PID Loop Bandwidth and Motion Control Performance

Building on over 50 years of motion control expertise, the Automation1 motion control platform contains some of the highest performing drive hardware available on the market today. To demonstrate how Automation1 outperforms Aerotech’s previous generation of drive hardware products, the Automation1-XR3 was compared to the A3200 Npaq. For this comparative test, an unloaded NEMA rotary…

Automation1 Linear Servo Drive Products Provide Industry-Leading In-Position Stability

Aerotech’s Automation1 linear amplifier products provide industry-leading in-position stability performance. The Automation1 XR3 multi-axis drive rack can be configured with up to six individual XSL3 amplifiers. The Automation1 XL2e enhanced, compact linear servo drive is a single-axis version that uses similar technology. Both the XR3 with XSL3 amplifiers and the XL2e drive use low-noise linear…

Automation1 Motion Control Platform Improves Laser Scan System Tracking Performance

Precision laser scanning systems are characterized by their ability to perform challenging contoured motion while maintaining the desired path position. One might refer to this as the “minimal tracking error” or “minimal following error.”  Many factors are involved in delivering high-throughput, highly-accurate laser scanning systems. For simplicity, there are two main technical components that must…

Advanced Motion Control Optimizes Mechanical Micro-Drilling

In micro-drilling process equipment, the most popular ways to create microvias (blind or buried vias with a diameter ≤150 µm) are mechanical drilling and laser drilling. Mechanical drilling is mainly used in larger apertures such as PCBs or IC substrates. Laser drilling is mainly used in finer apertures such as silicon wafers, ceramic substrates and…

Part-Speed Position Synchronized Output

Part-Speed Position Synchronized Output (PSO) is an effective tracking mode for Aerotech’s PSO advanced controller feature. Part-Speed PSO commands high-speed, low-latency output pulses based on the commanded vector velocity. Extending PSO Capabilities Aerotech’s PSO controller feature has long been used by industrial and research users alike to command their process tool – a laser, sensor,…

High-Bandwidth Force Control

Traditionally, linear stages are used with encoders to position to precise points in a motion profile. These encoders are used for both positioning and, in the case of brushless servomotors, for motor commutation as well. However, in certain applications like material press-bonding, position is not as important as force. When binding two materials together, if…

Aerotech’s EasyTune Advanced Autotuning Tool

When a user finds that the accuracy of a motion control application is low, such as unacceptable following error due to friction, low frequency disturbance, etc., they will normally first increase the servo loop gains to reduce the following error. Unfortunately, this “quick fix” can result in excess gains that make the system unstable. In…

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.…
