SGDB-1AADG YASKAWA Filter Modules

Product  Description：

Yaskawa Filter Modules are specialized power quality components designed to work in conjunction with AC drives, servo amplifiers, and machine controllers. These modules serve as the primary defense against electromagnetic interference (EMI) and radio frequency interference (RFI) generated by high-speed switching power electronics. By suppressing electrical noise and harmonic distortion, these filters protect sensitive control electronics and ensure that the entire automation system complies with global electromagnetic compatibility (EMC) standards.

Product Parameters

The technical characteristics of Yaskawa Filter Modules are defined by their electrical suppression capabilities and power ratings:

• Rated Current: Available in a wide spectrum ranging from low-power 3A units for small servo drives to high-capacity 400A+ versions for large industrial inverters.

• Operating Voltage: Supports standard industrial power grids, including single-phase 200V-240V AC and three-phase 200V, 400V, and 480V AC configurations.

• Frequency Range: Optimized for standard 50/60 Hz power lines, with attenuation capabilities extending into the megahertz (MHz) range for high-frequency noise.

• Leakage Current: Engineered with specific capacitance values to keep leakage current within safety limits, typically ranging from 1.5mA to 100mA depending on the model.

• Insertion Loss: Provides significant signal attenuation, often exceeding 40dB to 60dB in the critical frequency bands where interference is most prevalent.

• Operating Temperature: Rated for industrial environments, typically maintaining full performance between -25°C and 50°C without derating.

Product Advantages

Integrating Yaskawa Filter Modules into a system provides essential benefits for both the machinery and the surrounding electrical environment:

• Regulatory Compliance: Helps machinery meet CE, UL, and localized EMC directives by reducing conducted emissions to levels below mandated limits.

• Protection of Sensitive Electronics: Prevents high-frequency noise from traveling back into the power line, which protects PLCs, sensors, and communication modules from erratic behavior or hardware failure.

• Extended Equipment Life: By smoothing the electrical "noise" and reducing the stress on the insulation of motors and cables, these filters contribute to a longer service life for the entire system.

• Improved Communication Stability: Minimizes the risk of data packet loss in high-speed industrial networks like MECHATROLINK or Ethernet by maintaining a clean electrical ground.

• Compact and Integrated Design: Many Yaskawa filters are designed "footprint" style, allowing them to be mounted directly behind the drive to save valuable space inside the control cabinet.

Product Applications

Filter modules are utilized across all industries where precision control and electrical stability are required:

• Precision Robotics: Used in robotic cells to prevent servo switching noise from interfering with delicate vision systems or force sensors.

• Semiconductor Processing: Essential in cleanroom environments where ultra-stable power is required for wafer fabrication and chemical mechanical polishing (CMP) tools.

• CNC Machining Centers: Suppressing noise in high-speed spindles and multi-axis milling machines to ensure smooth surface finishes and accurate dimensions.

• Medical Imaging Equipment: Providing clean power to the drives used in MRI or CT scanners, where electrical noise could degrade image quality.

• Automated Material Handling: Ensuring that long cable runs in warehouse sorting systems do not act as antennas that broadcast interference to nearby electronics.

Important Precautions

To ensure maximum effectiveness and safety, the following guidelines must be followed during installation:

• Correct Grounding: The filter module must be mounted on a conductive, unpainted metal plate that is securely connected to the system's main earth ground. Use short, thick wires or braided straps for grounding to minimize impedance.

• Input/Output Separation: Never run the input wires (line side) and output wires (load side) of the filter in the same conduit or bundle. This "cross-talk" allows noise to bypass the filter entirely.

• Proximity to Noise Source: Install the filter as close to the drive or noise-generating component as possible. Long leads between the filter and the drive can diminish the filter's effectiveness.

• Heat and Airflow: Filter modules can become warm during operation due to internal losses. Ensure there is sufficient clearance around the module for natural convection and avoid placing it near other high-heat components.

• Wiring Polarity and Phases: For three-phase filters, ensure that the phase sequence is maintained and that all connections are torqued to the manufacturer's specification to prevent localized heating or arcing.
