- Suppress Conducted Emissions: Filters high-frequency interference signals generated by the rectifier circuit of the servo drive's power module, preventing these signals from propagating to the public power grid and interfering with other electrical equipment (e.g., sensors, PLCs, communication devices).
- Reduce Radiated Interference: Reduces electromagnetic radiation from the drive system's input power line, helping the entire equipment meet industrial EMC emission standards and avoid certification failures.
- Improve Immunity: Enhances the drive system's resistance to external interference from the power grid (e.g., voltage spikes, surges), reducing system malfunctions caused by grid fluctuations.
- System Compatibility: Designed specifically for SINAMICS S120 power modules, ensuring seamless integration without affecting the drive's dynamic performance.
- High-Precision Manufacturing Equipment: Such as CNC machining centers, precision grinding machines, and semiconductor manufacturing equipment—where electromagnetic interference can affect machining accuracy or sensor feedback.
- EMC-Sensitive Environments: Factories with dense electronic equipment (e.g., electronics assembly lines, pharmaceutical production lines) or environments requiring strict EMC compliance (e.g., aerospace component manufacturing).
- Public Grid Connection: Systems connected to the municipal power grid that need to comply with local EMC regulations to avoid penalties or disruptions to adjacent facilities.
- Matching High-Power Drives: Specifically paired with 25kW-class SINAMICS S120 power modules to address interference issues of high-power drive systems.
- Mandatory Matching: Exclusively designed for SINAMICS S120 non-regenerative power modules with 34A rated input current (e.g., 6SL3330-7TG41-3AA3). Not compatible with regenerative power modules or modules of other power ratings.
- Auxiliary Components: Should be installed close to the power module (distance ≤ 50cm) to ensure filtering effectiveness. No additional components (e.g., contactors) are allowed between the filter and the power module.
- Power Supply Requirements: Must be used with a three-phase AC power supply that meets 380-480V specifications; overvoltage may cause permanent damage to the filter.
- Electrical Safety: Installed by qualified electrical engineers in accordance with Siemens' EMC installation guidelines. Ensure reliable grounding (the filter's PE terminal must be connected to the cabinet's protective ground with a cross-sectional area ≥ 16mm²).
- Mounting Distance: Install directly adjacent to the matched power module to minimize the length of unfiltered power lines, which otherwise reduces filtering efficiency.
- Wiring Specifications: Use shielded cables for input and output wiring, and ensure the shield is grounded at both ends to enhance interference suppression.
- Maintenance Notes: The filter has no replaceable parts; if it fails (e.g., internal fuse blown, abnormal heating), it must be replaced entirely (do not disassemble for repair).
- Environmental Requirements: Avoid installation in environments with high temperature (>40°C), high humidity (>90% RH, non-condensing), dust, or corrosive gases—these can accelerate component aging.
- Classified as a standard EMC component for Siemens SINAMICS S120. Purchase through official authorized distributors to ensure compatibility and compliance with EMC standards.
