SGDC-50AJA YASKAWA Filter Modules

Product  Description：

Yaskawa Filter Modules are essential auxiliary components designed to work in tandem with servo drives and variable frequency drives (VFDs). Their primary function is to suppress electromagnetic interference (EMI) and radio frequency interference (RFI) generated by high-speed switching power electronics. By filtering out electrical noise on both the input (line) and output (load) sides, these modules ensure that the automation system complies with global EMC (Electromagnetic Compatibility) standards while protecting sensitive peripheral electronics from corruption.

Product Parameters

The technical specifications of Yaskawa Filter Modules are centered on electrical capacity and noise attenuation characteristics:

• Rated Voltage: Supports a wide range of industrial power supplies, including single-phase 200V AC and three-phase 200V/400V AC systems.

• Rated Current: Available in various capacities ranging from small 5A units for micro-servos to high-capacity units exceeding 1000A for large-scale industrial drives.

• Operating Frequency: Optimized for standard 50Hz and 60Hz power grids, with a high-frequency attenuation range typically spanning from 150kHz to 30MHz.

• Leakage Current: Designed with specific limits to prevent nuisance tripping of Earth Leakage Circuit Breakers (ELCBs), often categorized into standard and low-leakage models.

• Insertion Loss: High attenuation performance, often reaching 40dB to 60dB in the critical frequency bands to ensure quiet electrical environments.

• Environmental Rating: Built to operate in industrial temperatures ranging from -10°C to 50°C, often with IP20 or IP00 protection ratings.

Product Advantages

Integrating Yaskawa Filter Modules into a motion control system provides several critical operational benefits:

• EMC Compliance: Enables machinery to meet strict CE, UL, and localized electromagnetic radiation standards, which is mandatory for exporting equipment to international markets.

• Signal Integrity Protection: By suppressing "noise" on the power lines, these filters prevent data errors in communication cables, sensor feedback loops, and PLC logic circuits.

• Extended Equipment Life: Reduces the high-frequency voltage stress on motor windings and bearings, which helps prevent premature insulation breakdown and electrical pitting.

• Improved System Stability: Minimizes the risk of unexpected system resets or "ghost" alarms caused by electrical spikes and harmonic distortion.

• Optimized Drive Performance: Ensures that the servo drive receives "clean" power, which can lead to more stable torque delivery and smoother motor rotation at low speeds.

Product Applications

These modules are used across all sectors where high-performance motion control is implemented:

• Precision CNC Machining: Ensuring that the high-frequency switching of the spindle drive does not interfere with the delicate touch probes or laser measurement systems.

• Semiconductor Fabrication: Maintaining an electrically clean environment for vacuum pumps and wafer-handling robotics where even minor interference can ruin a production batch.

• Medical Equipment: Filtering power supplies for automated laboratory analyzers and imaging tables to prevent interference with sensitive diagnostic electronics.

• Automated Assembly Lines: Protecting networked sensors and vision systems from the electrical noise generated by multiple synchronized servo axes.

• Lifts and Escalators: Reducing the electrical noise feedback into the building's main power grid, preventing interference with other office or residential electronics.

Important Precautions

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

• Short Lead Lengths: Keep the wiring between the filter and the drive as short as possible. Long wires act as antennas, re-radiating the noise that the filter is trying to suppress.

• Correct Grounding: The filter module must be mounted on a conductive, unpainted metal backplane. Ensure the ground terminal is connected to a central earth point using a thick, flat braided strap for high-frequency conductivity.

• Input and Output Separation: Never bundle the input wires (clean side) and output wires (noisy side) together. This "cross-talk" allows noise to bypass the filter entirely.

• Thermal Considerations: Filters can become warm during operation due to internal losses. Ensure there is adequate clearance around the module for airflow and avoid mounting it directly below heat-sensitive components.

• Selection Matching: Always match the filter's rated current to the drive's input current, not the motor's rated current. Oversizing a filter is generally safe, but undersizing will lead to overheating and potential fire hazards.
