JANCD-SR21-1 YASKAWA Servo Controller

Product  Description：

Yaskawa Servo Controllers, particularly the world-renowned Sigma series, are high-precision electronic devices designed to regulate the position, velocity, and torque of servo motors. Acting as the intermediate power and logic interface, these controllers (often called Servo Packs) receive low-level command signals from a host controller and translate them into high-power electrical pulses. Known for their "Tuning-less" technology and industry-leading frequency response, Yaskawa controllers are foundational to high-speed automation and robotics.

Product Parameters

The technical performance of a Yaskawa Servo Controller is defined by its electrical capacity and control frequency:

• Input Voltage Options: Supports single-phase or three-phase 100V, 200V, and 400V AC power inputs, depending on the specific model and regional requirements.

• Speed Frequency Response: High-end models like the Sigma-7 feature a response frequency of 3.1 kHz, allowing for extremely fast following of command signals.

• Encoder Support: Compatible with high-resolution 24-bit absolute encoders, providing over 16 million pulses per revolution for nanometer-level precision.

• Communication Protocols: Integrated support for MECHATROLINK-III, MECHATROLINK-4, EtherCAT, and traditional analog/pulse train interfaces.

• Overload Capacity: Capable of handling instantaneous peak currents up to 300 percent of the rated current for rapid acceleration and deceleration.

• Control Modes: Includes built-in modes for position control, speed control, torque control, and internal multi-step speed regulation.

Product Advantages

Yaskawa is a market leader due to several proprietary technologies that simplify installation and maximize performance:

• Tuning-less Function: This industry-first technology allows the servo to operate immediately without manual gain adjustment, even when the load-to-rotor inertia ratio reaches 30:1.

• Vibration Suppression: Features advanced "Notch Filters" and "Anti-Resonance Control" that automatically detect and eliminate mechanical resonance and vibrations during high-speed movement.

• High Energy Efficiency: Utilizes high-efficiency power modules and regenerative energy processing to minimize heat loss and reduce electricity consumption.

• Safety Integration: Built-in functional safety features such as Safe Torque Off (STO) comply with global SIL3/PLe standards, reducing the need for external safety hardware.

• Extreme Compactness: The advanced internal cooling design and high-density component mounting allow Yaskawa to offer some of the smallest drive footprints in the industry, saving valuable control cabinet space.

Product Applications

These controllers are utilized in any application where precise, repeatable motion is required:

• Industrial Robotics: Driving the joints of 6-axis articulated robots and SCARA robots for welding, painting, and assembly.

• Semiconductor Lithography: Managing the ultra-precise positioning stages used in wafer inspection and chip manufacturing.

• Metalworking and CNC: Controlling the feed axes and spindles of high-speed milling machines, laser cutters, and EDM equipment.

• Battery Manufacturing: Providing the high-speed synchronization required for coating, slitting, and stacking processes in lithium-ion battery production.

• Medical Equipment: Driving the motion systems in CT scanners, surgical robots, and automated laboratory sampling systems.

Important Precautions

To ensure the safety of the operator and the longevity of the hardware, the following precautions are critical:

• Regenerative Resistor Wiring: For high-inertia loads or frequent deceleration, an external regenerative resistor may be required. Ensure it is wired correctly to the B1 and B2 terminals; otherwise, the drive may fail due to overvoltage.

• Heat Management: When installing multiple controllers side-by-side (zero-stacking), ensure the ambient temperature does not exceed the derated limit. Provide forced-air cooling if the cabinet air circulation is poor.

• Encoder Cable Handling: Never pull or tightly bend the encoder cables. The high-resolution signals are sensitive to physical stress and electrical interference, which can lead to feedback errors or "Encoder Communication" alarms.

• Grounding (PE): Always connect the Protective Earth terminal of the controller to the main ground bus. Improper grounding can lead to erratic behavior, electrical noise, or dangerous leakage currents on the machine frame.

• Power-On Sequence: When using a separate control power supply and main power supply, ensure the control power is stabilized before the main power is applied to prevent initialization errors.
