Product catalog summary

Overview
Walter Uhl is a leading supplier of high-precision drive solutions, specializing in precision mechanics since 1943. The company provides a variety of linear and rotary stages, motion controllers, stands, and customized systems for research, science, and industry.

Linear Stages
LT Series: These stages are compact and highly accurate, with travel ranges from 50 to 300 mm. They include protective bellows and offer various configurations with different motors and measuring systems.
PT Series: More accurate and with higher load capacity than the LT series, these stages are suitable for vertical axis use, with travel ranges from 25 to 300 mm.

XY Stages
KT Series: Designed for measuring microscopy, these stages support transmitted light capture and thickness measurement of flat components, with travel ranges from 50 x 50 mm to 420 x 300 mm.

Key Features

High precision and accuracy with straightness and flatness specifications.
Various motor options including stepper and DC motors.
Customizable configurations with options for encoders and motors.
Materials include stress-relieved aluminum alloy, often anodized for durability.

Applications
These systems are used in specialized setups for measuring semiconductor structures and shaving heads.

Specifications and Configurations
The document details various models of XY stages, rotary stages, and lift stages, each with specific travel ranges, materials, guiding systems, and drive mechanisms. The stages are made from stress-relieved aluminum alloy, black anodized, and feature backlash-free preloaded guides and ballscrews.

Accuracy and Measuring Systems
Accuracy classes are specified, with straightness and flatness tolerances ranging from 1 µm to 6 µm. Measuring systems include linear encoders with a 20 µm pitch and rotary encoders, ensuring high positioning accuracy.

Motors and Drives
The stages are equipped with various motors, including stepper motors, DC motors, and ironless linear motors. Some stages are manually operated with coarse and fine drives.

Options and Customization
Options for custom motors, encoder signals, and different encoder pitches are available. Custom configurations and sample setups for specific applications are also mentioned.

Applications and Accessories
The stages are designed for high-precision applications in surface metrology and positioning systems. Accessories include stands and adapter plates made from granite, grey cast, or aluminum.

Specifications
Various models of stages and adapter plates are listed with their dimensions and compatibility. Motion controllers are described with their capabilities, including the number of axes they can control, motor speed, step resolution, and power supply requirements.

Procedures
The document outlines the use of motion controllers for precise positioning, with options for joystick or PC control via RS232 or USB interfaces. It also details the setup of adapter plates and brackets for mounting various stages and equipment.

Standards and Recommendations
Controllers operate in vector mode for smooth motor operation and include features like limit switches and position data processing. Recommendations for power supply and interface options are provided.

Key Data from Tables and Diagrams
Technical data for motion controllers include motor speed, step resolution, motor current, and voltage. Wiring diagrams for stepper and DC motors are provided.

Critical Information
The F9S-3-M controller supports up to 3 axes with a maximum motor speed of 40 rev/s and a step resolution of 50,000 steps/rev. The F9L-3-M servo controller supports high precision operations with a maximum motor current of 10 A for one axis and a voltage of 48 V. Adapter plates and brackets are essential for mounting and compatibility with various stages.
