YAMAHA Orbit Type SCARA YK-TW Series

Product catalog summary

Introduction
Yamaha has introduced the YK-TW series, expanding their SCARA robot lineup with the YK350TW and YK500TW models. These robots are designed for high-speed operations and superior positioning accuracy, featuring a ceiling-mount configuration that allows 360° arm rotation.

Specifications
The YK350TW and YK500TW models have specific features:

YK350TW: Arm length of 250 mm, repeatability of ±0.01 mm, maximum speed of 5.6 m/sec, and a payload capacity of 5 kg.
YK500TW: Arm length of 250 mm, repeatability of ±0.015 mm, maximum speed of 6.8 m/sec, and a payload capacity of 5 kg (RCX340) or 4 kg (RCX240).

Both models use harmonic drive and ball screw mechanisms for speed reduction and are equipped with AC servo motors.

Advantages
The YK-TW series offers several benefits over traditional SCARA and parallel-link robots:

Cycle time reduced by approximately 36% compared to previous models.
Compact design with a height of 392 mm and a weight of 27 kg, minimizing equipment footprint.
High precision with repeated positioning accuracy of ±0.01 mm.
Environment-resistant design for harsh conditions.

Applications
The YK-TW series is suitable for various applications, handling payloads up to 5 kg and accommodating heavy arm-end tools, ideal for high-speed, high-precision assembly systems.

Installation and Configuration
The robots are easy to install with a hollow construction for the Y-motor and reduction gear, allowing internal housing of components. Parameter adjustments may be needed for the R-axis moment of inertia when the payload exceeds 4 kg.

Controller Specifications
The RCX240 and RCX340 controllers support up to 4 axes with expansion options. They feature AC full digital servo drive methods and support control methods like PTP motion and linear interpolation.

Conclusion
The YK-TW series SCARA robots by Yamaha enhance productivity, precision, and flexibility, making them valuable for automated systems requiring high-speed and accurate operations.

Control System Specifications
The control system supports up to 100 programs with a maximum of 9999 lines per program and can handle up to 30000 points. It includes teaching methods such as MDI, direct teaching, and offline teaching.

System Backup
Internal memory backup is supported by a lithium battery with a 4-year service life and 512 KB of internal flash memory.

Safety and I/O
The system includes emergency stop inputs, service mode inputs, and motor power ready outputs, supporting external communications via RS-232C, RS-422, Ethernet, and USB.

General Specifications
Operating temperature ranges from 0 to 40 °C, with storage temperatures from -10 to 65 °C. The system meets noise immunity standards IEC61000-4-4 Level 3 and has a protective structure rating of IP10/IP20.

Options and Expansion
The system offers optional boards with up to 4 slots for parallel I/O and serial I/O expansions, supporting communication protocols like CC-Link, DeviceNet, PROFIBUS, and EtherNet/IP.

Controller Options
The document details ordering methods for controllers, specifying options for controllable axes, safety standards, and additional features like gripper control and tracking.

Notes
Guidance is provided on selecting options, such as not mixing NPN and PNP specifications and choosing only one master or slave board for YC-Link/E.

Advantages of YK-TW Series SCARA robot over conventional SCARA and parallel-link robots. User: We want a smaller equipment footprint. YK-TW can move anywhere through the full $ 1000 mm*2 work envelope. Featuring a ceiling-mount configuration with a wide arm rotation angle, the YK-TW can access any point within the full $ 1000 mm downward range. This eliminates all motion-related restrictions with regard to pallet and conveyor placement operations, while dramatically reducing the equipment footprint. range User: We need to reduce cycle time. Standard cycle time of 0.29 secs.*2 Y-axis (arm 2) passes...
