I5MADU0000000S LENZE Filter Modules

Product  Description：

Lenze Filter Modules are specialized electronic components designed to ensure electromagnetic compatibility (EMC) within industrial drive systems. They work in conjunction with frequency inverters and servo drives to suppress radio frequency interference (RFI) and electromagnetic interference (EMI) generated by high-frequency switching power semiconductors. By filtering out unwanted electrical noise, these modules protect sensitive peripheral equipment and ensure compliance with strict global EMC directives.

Product Parameters

The technical baseline of a Lenze Filter Module is defined by its attenuation performance and electrical ratings:

• Rated Operating Voltage: Typically designed for single-phase 230V AC or three-phase 400V to 480V AC power grids, covering standard industrial mains voltages.

• Rated Current Capacity: Available in a wide spectrum of current ratings, ranging from 4 Amperes for compact micro-drives up to several hundred Amperes for heavy-duty multi-axis inverter systems.

• Mains Frequency: Universally compatible with 50Hz and 60Hz power distribution networks.

• Maximum Motor Cable Length: Specially rated to maintain effective noise suppression even when driving motors over long, shielded cable distances up to 50 or 100 meters.

• Dissipation Power: Optimized low-loss internal design, minimizing thermal dissipation to ensure efficiency within control enclosures.

• Climatic Environmental Class: Engineered to operate continuously within ambient temperature ranges from -25°C up to 55°C, with derating options for higher thermal demands.

Product Advantages

Integrating a genuine Lenze Filter Module provides distinct operational and regulatory benefits for automated machinery:

• Strict Regulatory Compliance: Enables drive systems to meet the highest emission standards, allowing machines to be certified for CE, UL, and other international markets easily.

• Footprint Optimization: Many Lenze filter modules feature a footprint or "book-style" design, allowing them to be mounted directly underneath or adjacent to the inverter, saving critical space on the enclosure mounting plate.

• Enhanced System Reliability: By suppressing high-frequency interference on the mains supply, the filter prevents erratic behavior, data corruption, and timing faults in nearby PLCs, sensors, and communication networks.

• Reduced Motor Stress: Helps in mitigating common-mode currents and voltage spikes, which indirectly contributes to reducing premature bearing wear and insulation breakdown in the connected AC motors.

• Perfect Ecosystem Matching: Tailored specifically to match the electrical characteristics, mounting dimensions, and thermal profiles of Lenze i500, 8400, and 9400 drive series, eliminating guesswork during component selection.

Product Applications

These filtration units are essential across automated industries where precision and noise control are paramount:

• Material Handling and Logistics: Suppressing electrical noise across expansive conveyor systems, automated storage retrieval units, and sorting machinery driven by multiple variable frequency drives.

• Packaging Technology: Ensuring precise, interference-free signal transmission for high-speed indexing, filling, and wrapping machines where sensors operate in close proximity to power electronics.

• Textile Production Machinery: Protecting sensitive electronic yarn tensioners and pattern control computers from the heavy electrical noise generated by large motor groups.

• Automotive Assembly Lines: Implementing clean power distribution zones for robotic welding, lifting stations, and multi-axis positioning systems.

• Printing and Paper Conversion: Preserving the integrity of high-speed registration marks and encoder feedback loops by eliminating cross-talk from the drive mains.

Important Precautions

To guarantee safe operation and maximum noise suppression effectiveness, the following implementation guidelines must be followed:

• Low-Impedance Grounding: The filter module must be mounted flat against a conductive, unpainted metal backplane. Achieving a broad-surface, low-impedance RF ground connection is critical; standard wire grounding alone is insufficient for high-frequency noise suppression.

• Shielded Cable Separation: Output cables leading from the filter to the inverter, and from the inverter to the motor, must be shielded. Never route filtered input lines parallel to unfiltered output lines in the same wire duct, as this causes the noise to bypass the filter via capacitive coupling.

• Discharge Current Hazard: Due to the internal capacitors connected between the phases and earth, these modules exhibit higher leakage currents. Ensure a permanent, robust protective earth (PE) connection is established before applying power to prevent electrical shock hazards.

• Insulation Testing Restriction: Disconnect the filter module completely from the circuit before performing high-voltage insulation tests or megger testing on the control panel, as the testing voltages can destroy the internal capacitor networks.

• Strict Current Limits: Never exceed the rated continuous current of the filter module. Overcurrent conditions can lead to core saturation in the internal chokes, causing a catastrophic drop in filter performance and extreme thermal overheating.
