Yaskawa UAASKE-11WES11

The UAASKE-11WES11 is a servo drive system developed by YASKAWA Electric specifically for high-precision industrial automation applications. Featuring a compact design, it is ideal for direct integration into space-constrained machine units, enabling integrated drive-control-feedback functionality. The system delivers high-speed, low-inertia motion control and is widely deployed in scenarios requiring precise positioning, such as robotics, CNC machine tools, and packaging equipment.

Key Technical Specifications

• Rated Power: Approx. 11 kW (compatible with 11 kW-class servo motors)
• Rated Voltage: 400 V three-phase AC (200 V/230 V optional)
• Rated Speed: Up to approx. 6000 rpm (varies by matched motor)
• Peak Torque: Approx. 30 Nm (depends on motor specifications)
• Control Method: Digital servo control, supporting industrial fieldbuses including EtherCAT, PROFINET, and CANopen
• Dimensions/Weight: Compact profile and lightweight design for easy installation

Product Features

1. High-Precision Motion Control
    

   Equipped with YASKAWA’s proprietary high-resolution encoder and advanced vector control algorithm, the system achieves submicron-level positioning accuracy.

2. Easy Integration
    

   Its modular structure allows direct embedding into robot joints or machine tool headstocks. Companion programming software (e.g., MotoPlus) simplifies parameter configuration.

3. Robust and Durable
    

   The metal-cast housing and dust-proof, moisture-proof internal components ensure stable long-term operation even in harsh industrial environments.

4. Energy Efficiency
    

   The low-power-consumption design minimizes no-load power loss, helping reduce the overall energy consumption of the system.

5. User-Friendly Interface
    

   The integrated graphical HMI enables quick commissioning and fault diagnosis, making it accessible even for operators with limited experience.

Structure and Components

• Drive Unit: Includes power module, power semiconductors (IGBT/SiC), and heat dissipation system.
• Control Unit: Built-in DSP/FPGA processor for closed-loop control, communication protocol stack management, and safety monitoring.
• Encoder Interface: Supports incremental or absolute encoders, providing high-speed feedback signals.
• Power Interface: Three-phase input terminals with overcurrent, overvoltage, and undervoltage protection.
• Communication Ports: Multiple fieldbus interfaces including EtherCAT, PROFINET, CANopen, and RS-485.
• Heat Dissipation Device: Air-cooled or water-cooled options available to ensure thermal management under high-load operation.

Typical Application Fields

• Industrial robots (6-axis robots, collaborative robots, transfer arms)
• CNC machine tools (turning, milling, laser processing)
• High-speed packaging and printing equipment
• Automated assembly lines (precision assembly, dispensing)
• Semiconductor and optoelectronic manufacturing (lithography, inspection platforms)

Installation and Maintenance Guidelines

Pre-Installation Checks

1. Verify that the power phase sequence and rated voltage match system requirements.
2. Inspect the tightness of chassis fixing bolts and heat sinks to prevent loosening due to vibration.

Wiring Specifications

1. Use dedicated shielded terminals in accordance with the wiring diagram. Ensure separate routing of three-phase power, grounding, and signal lines to avoid electromagnetic interference.
2. Adopt shielded twisted-pair cables for fieldbuses (e.g., EtherCAT) and install terminal resistors at both ends of the bus.

Commissioning Procedures

1. Import parameters via YASKAWA MotionWorks or MotoPlus software. Conduct a no-load speed test first to confirm the absence of abnormal noise or overheating.
2. Gradually apply load while monitoring current, temperature, and torque curves to ensure operation within rated limits.

Routine Maintenance

1. Inspect the cleanliness of cooling fans or water-cooling systems every 6 months; replace fans or clean cooling pipelines when necessary.
2. Regularly check encoder connections and signal integrity to prevent signal loss caused by dust accumulation or mechanical shock.
3. Record operation logs and use the built-in fault diagnosis function to quickly locate abnormalities.

Fault Handling

1. Overcurrent/Overvoltage: The system will shut down automatically and trigger an alarm. Check power quality or sudden load changes.
2. Communication Interruption: Inspect fieldbus terminals, cable shielding, and network configuration.
3. Temperature Rise: Confirm that the heat dissipation device is functioning properly and check if the ambient temperature exceeds the rated upper limit (typically 45°C).
