High Speed, High Precision Linear Motor Stages with Built-in Controllers - X-LDQ-AE

The X-LDQ-AE Series devices are linear motor stages with high precision and speed capabilities.

The X-LDQ-AE's innovative design allows speeds up to 1.5 m/s and minimum incremental move of 50 nm. The built-in controller and linear encoder allows pre-tuned closed-loop servo positioning with adjustable tuning parameters. An optional indexed knob provides convenient manual control for versatile operation even without a computer.

Features include:
• Integrated linear encoder provides high accuracy closed loop servo positioning
• Up to 2 g acceleration; 75 - 1000 mm travel options
• Up to 2.5 µm accuracy over 1000 mm travel
• Zero backlash

ST Robotics Develops the Workspace Sentry for Collaborative Robotics

The ST Robotics Workspace Sentry robot and area safety system are based on a small module that sends an infrared beam across the workspace. If the user puts his hand (or any other object) in the workspace, the robot stops using programmable emergency deceleration. Each module has three beams at different angles and the distance a beam reaches is adjustable. Two or more modules can be daisy chained to watch a wider area. "A robot that is tuned to stop on impact may not be safe. Robots where the trip torque can be set at low thresholds are too slow for any practical industrial application. The best system is where the work area has proximity detectors so the robot stops before impact and that is the approach ST Robotics has taken," states President and CEO of ST Robotics David Sands.
