SGDH-20AE-N2-RY49 YASKAWA Servo Controller

Product  Description：

Yaskawa Servo Controllers, widely recognized under the Sigma-7 and Sigma-10 series, are high-performance industrial amplifiers designed to precisely regulate the speed, torque, and position of rotary, linear, and direct-drive servomotors. Operating as the execution core of a motion system, these controllers close the loop between feedback devices (encoders) and the main command unit. They utilize advanced tuning algorithms to ensure smooth, high-speed, and ultra-precise mechanical movement in demanding manufacturing environments.

Product Parameters

The technical baseline of a Yaskawa Servo Controller focuses on electrical compatibility, response frequency, and encoder interface capabilities:

• Input Voltage Range: Available in single-phase or three-phase 200V to 240V AC, and three-phase 380V to 480V AC to match global industrial power standards.

• Supported Motor Outputs: Controls a broad wattage spectrum, typically from small 50W capacity motors up to high-capacity 15kW industrial motors.

• Speed Frequency Response: Features high-speed loop processing with bandwidths often reaching 3.1 kHz, minimizing path deviation during rapid acceleration.

• Encoder Feedback Support: Tailored for high-resolution feedback, natively supporting 24-bit absolute encoders that provide over 16 million pulses per revolution.

• Control Command Interfaces: Supports built-in digital networking via MECHATROLINK-III, MECHATROLINK-4, EtherCAT, or traditional analog voltage and pulse train commands.

• Built-in Safety Features: Includes integrated Safe Torque Off (STO) functions compliant with international functional safety standards like SIL3 and PLe.

Product Advantages

Yaskawa Servo Controllers are distinguished by their ease of setup, vibration suppression, and exceptional reliability:

• Advanced Auto-Tuning: Features "tuning-less" technology that allows the system to operate stably without manual adjustment, automatically compensating for changing load inertias up to a 30:1 ratio.

• Advanced Vibration Suppression: Implements notch filters and vibration suppression algorithms that eliminate both high-frequency mechanical resonance and low-frequency sloshing or tip vibration.

• Extreme Positioning Accuracy: When paired with high-resolution encoders, the controller can execute micro-positioning down to the sub-micron level, which is critical for semiconductor and optical alignment.

• High Energy Efficiency: Utilizes advanced power semiconductor topologies that reduce heat losses within the controller casing, allowing for compact panel installations.

• Thermal and Status Monitoring: Real-time tracking of internal component temperatures, current ripple, and total encoder cycles provides valuable data for predictive maintenance strategies.

Product Applications

These controllers are deployed in automation systems that demand rigorous dynamics and zero-error tracking:

• Semiconductor Fabrication: Driving the precision XY tables used in wafer lithography, inspection, and wire bonding processes.

• Robotic Arm Joints: Supplying the dynamic current and quick response needed for multi-axis articulated industrial robots and collaborative robots (cobots).

• Electronic Component Assembly: Powering high-speed "pick and place" surface mount technology (SMT) machines that handle micro-scale resistors and chips.

• Metal Working and CNC: Controlling the feed axes on precision laser cutters, water jets, and high-speed milling machines to ensure smooth surface finishes.

• Printing and Converting: Managing synchronized tension web control in printing presses and slitting machinery to prevent material stretching or tearing.

Important Precautions

To ensure safe installation and prevent damage to the controller circuitry, users must follow these essential guidelines:

• High Voltage Residuals: Internal capacitors retain dangerous high-voltage levels after the main power is turned off. Wait at least 5 minutes and verify that the charge indicator LED is completely unlit before touching terminal connections.

• Regenerative Energy Management: During rapid deceleration, the servomotor returns energy to the controller. If the internal regenerative resistor capacity is exceeded, an overvoltage alarm will trigger. In such cases, a correctly rated external regenerative resistor must be installed.

• Correct Grounding: Always connect the ground terminal of the servo controller to a dedicated protective earth ground. Poor grounding can lead to intermittent encoder communication faults and dangerous leakage currents on the machine frame.

• Encoder Cable Routing: Never route the sensitive encoder feedback cable in parallel with the high-voltage motor power cables. Maintain a physical separation or use grounded metal conduits to prevent inductive noise from corrupting position data.

• Cooling and Mounting Orientation: Install the controller vertically on a flat, non-combustible surface. Maintain the specified clear space above, below, and adjacent to the unit to ensure proper natural convection or fan-driven airflow can dissipate internal heat.
