SJDE-08ANA-OY YASKAWA Filter Modules

Product  Description：

Yaskawa Filter Modules are specialized electromagnetic compatibility (EMC) components designed to suppress electrical noise and harmonic distortion within automated systems. In high-speed motion control environments, the rapid switching of power semiconductors in servo drives and inverters creates high-frequency electromagnetic interference (EMI). Yaskawa filter modules are engineered to mitigate this interference, protecting sensitive control signals and ensuring the entire system complies with international EMC standards. These modules act as a protective barrier, preventing noise from leaking back into the power grid and shielding the machine's internal logic from external electrical disturbances.

Product Parameters

The technical profile of a Yaskawa Filter Module is defined by its attenuation capacity and power handling limits:

• Rated Voltage: Designed for standard industrial power systems, typically ranging from 200V to 480V AC, with specific models for single-phase and three-phase configurations.

• Rated Current: Available in a wide spectrum of current ratings, from 5A for small-scale servo systems to over 1000A for large-scale industrial inverter banks.

• Frequency Range: Optimized to suppress noise across a broad frequency spectrum, typically effective from 150kHz to 30MHz.

• Leakage Current: Engineered with high-quality capacitors to keep leakage current within safety limits, often specified at less than 3.5mA or 30mA depending on the industrial environment.

• Insertion Loss: High attenuation characteristics (measured in decibels) that significantly reduce both common-mode and differential-mode noise.

• Climatic Category: Rated for operation in demanding industrial climates, often specified under the 25/085/21 category (operating from -25°C to +85°C).

Product Advantages

Integrating Yaskawa Filter Modules into a control cabinet provides several critical performance benefits:

• Regulatory Compliance: Simplifies the process of meeting CE, UL, and high-level EMC directives, ensuring the machinery can be legally operated in global markets.

• System Reliability: By "cleaning" the electrical supply, these modules prevent erratic behavior in PLCs, sensors, and communication networks that are often caused by stray high-frequency noise.

• Motor Longevity: Certain types of output filters (like dV/dt filters) reduce the voltage stress on motor windings and bearings, extending the service life of the connected AC motors or servos.

• Improved Signal Integrity: Ensures that analog signals (such as 4-20mA or 0-10V) and high-speed encoder pulses remain crisp and accurate without the distortion caused by power switching.

• Space-Efficient Mounting: Many Yaskawa filters feature a "footprint" design, allowing them to be mounted directly behind the drive or inverter to save valuable space on the control panel backplate.

Product Applications

These modules are essential components in any environment where precision and power coexist:

• Precision CNC Machining: Protecting the high-resolution feedback loops of CNC spindles and axes from the noise generated by high-power cutting operations.

• Medical Equipment: Ensuring that power electronics in diagnostic machines do not interfere with sensitive imaging or monitoring sensors.

• Cleanroom Environments: Used in semiconductor and pharmaceutical manufacturing where electrical noise can disrupt highly sensitive robotic handling systems.

• Heavy Infrastructure: Installed in large-scale pumping stations and HVAC systems to prevent harmonic distortion from affecting the local power utility grid.

• Elevator and Escalator Systems: Maintaining smooth and quiet operation by filtering the switching noise from the main traction drives.

Important Precautions

To ensure the maximum effectiveness of the filter module and to maintain safety, the following guidelines must be followed:

• Proper Grounding: The filter module must have a solid, low-impedance connection to the metal mounting plate and the system ground. Paint or coatings on the mounting plate should be removed to ensure metal-to-metal contact.

• Wiring Separation: Input cables (clean side) and output cables (noisy side) must be kept separate. If they are routed together in the same wire duct, the noise will simply bypass the filter through inductive coupling.

• Cable Length: The distance between the filter and the drive should be as short as possible. Longer cables act as antennas, radiating noise before it can be suppressed by the filter.

• Thermal Considerations: Filter modules can generate heat during continuous operation. Ensure there is adequate clearance around the unit for natural convection or forced-air cooling.

• Voltage Verification: Never use a filter rated for 200V on a 400V system. The internal capacitors are rated for specific voltages, and exceeding these can lead to component rupture and fire hazards.
