Technical Specifications Overview

This document presents comprehensive technical data for various KUKA industrial robot models, categorized by series such as KR CYBERTECH, KR IONTEC, KR AGILUS, LBR iiwa, KR QUANTEC, KR FORTEC, and KR PA. Key parameters include payload capacities, reach dimensions, axis counts, positioning accuracy, robot weights, mounting options, joint movement ranges, and maximum joint speeds.

1. Payload and Reach Specifications

• Payload capacities range from 3 kg (KR IONTEC nano) to 1300 kg (KR 1000 titan PA), covering a broad spectrum of industrial needs.
• Maximum reach or Z-stroke varies from approximately 541 mm for the smallest models up to over 3900 mm for the largest robots, enabling diverse workspace coverage.
• Some models specify supplementary arm loads, indicating additional payload capacity beyond the rated payload.

2. Axes and Positioning Accuracy

• Most robots feature 6 axes, with select models offering 7 axes for enhanced flexibility.
• Positioning repeatability ranges from ±0.02 mm for high-precision models (notably the KR PA series) to ±0.15 mm for smaller or less precise units, supporting various precision requirements.

3. Robot Weight and Mounting Options

• Robot weights vary widely, from approximately 23.9 kg for compact models to over 4700 kg for heavy-duty robots, impacting installation and integration planning.
• Mounting configurations include wall, floor, ceiling, and angled positions, with some models restricted to floor mounting only.

4. Joint Movement Ranges and Speeds

• Joint rotation ranges typically span ±125° to ±185°, with some asymmetric ranges (e.g., +65°/–185°), defining the robot’s operational workspace.
• Maximum joint speeds vary by axis and model, ranging from about 50°/s for smaller joints to over 630°/s for high-speed axes, influencing cycle times and dynamic performance.

5. Special Features and Application Suitability

• Certain models support specialized applications such as arc welding and precision tasks requiring high accuracy.
• Travel-dependent parameters indicate performance variations based on reach or extension for some robots.
• Environmental adaptations include versions for cleanrooms, foundries, splash-proof designs, food-compatible lubricants, hygienic machines, and explosion-proof ratings.

7. Environmental and Compliance Considerations

• Robots are available in variants suitable for cleanrooms, foundry environments, and hazardous areas, with features like splash-proof covers and food-grade lubricants.
• Some models comply with IEC 60601-1 standards and are designed for hygienic or explosion-proof applications.
• Special configurations include ceiling-mounted and foundry-specific versions, with availability subject to contractual terms.

8. Conclusions and Recommendations

• Select robot models based on payload and reach requirements, ensuring compatibility with mounting and environmental constraints.
• For precision applications, prioritize models with repeatability of ±0.02 mm and high maximum joint speeds.
• Consider joint movement ranges and speeds to align with application dynamics and workspace needs.
• Specialized tasks such as arc welding require models with dedicated support and joint capabilities.
• Account for robot weight and footprint during installation and integration planning.

This structured technical data supports informed decision-making for selecting appropriate KUKA robotic solutions across diverse industrial applications.
