CACR-SR30BE12M-U YASKAWA Filter Modules

Product  Description：

Yaskawa Filter Modules are specialized electromagnetic compatibility (EMC) components designed to work in conjunction with AC drives, servos, and machine controllers. These modules are engineered to suppress high-frequency electromagnetic interference (EMI) and radio frequency interference (RFI) generated by the high-speed switching of power semiconductors. By filtering both the input power lines and output motor cables, these modules ensure that the automation system complies with global EMC standards and operates without disrupting sensitive electronic equipment nearby.

Product Parameters

The technical specifications of Yaskawa Filter Modules are focused on electrical attenuation and power handling capacity:

• Rated Voltage: Available for various power grids, typically ranging from 200V to 480V AC, in both single-phase and three-phase configurations.

• Rated Current: Scalable capacities designed to match drive ratings, commonly ranging from 5A for small servos to over 1000A for large-scale industrial inverters.

• Operating Frequency: Designed for standard power frequencies of 50Hz and 60Hz, while effectively filtering noise in the megahertz (MHz) range.

• Leakage Current: Engineered with specific capacitance values to keep leakage current within safe limits for Ground Fault Circuit Interrupters (GFCI).

• Insertion Loss: High attenuation performance, often providing 40dB to 60dB of noise reduction across a wide frequency spectrum.

• Environmental Rating: Typically rated for IP00 or IP20, requiring installation within a protected electrical cabinet.

Product Advantages

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

• Regulatory Compliance: Helps machinery meet CE, UL, and localized EMC directives by keeping conducted and radiated emissions below legal limits.

• Enhanced Signal Integrity: Prevents electrical noise from "leaking" into low-voltage control lines, which reduces the risk of PLC logic errors and sensor flickering.

• Equipment Longevity: By smoothing out voltage spikes and reducing high-frequency stress on motor insulation, filters can contribute to a longer service life for connected motors.

• Improved Communication Stability: Reduces interference that can cause "dropped packets" or CRC errors in high-speed communication networks like MECHATROLINK or Ethernet.

• Compact Footprint: Many Yaskawa filters are designed as "footprint" filters, meaning they can be mounted directly behind the drive to save valuable space on the cabinet backpanel.

Product Applications

These modules are essential in environments where electrical "cleanliness" is a priority:

• Medical and Laboratory Equipment: Ensuring that industrial-grade automation used in pharmaceutical production does not interfere with sensitive diagnostic imaging tools.

• Precision Manufacturing: Used in semiconductor and optical lens production where even minor electrical noise can disrupt high-precision positioning.

• Commercial HVAC: Reducing interference in office buildings or hospitals where the same power grid supports both large fans and sensitive IT infrastructure.

• High-Speed Printing and Textiles: Protecting the synchronized communication between dozens of servo axes from the noise generated by high-power motors.

• Elevator and Escalator Systems: Preventing drive noise from affecting building-wide communication and security systems.

Important Precautions

To ensure the filter module functions effectively, the following installation and safety rules must be followed:

• Grounding Integrity: The filter must have a solid, low-impedance connection to the electrical ground. Ensure the mounting plate is unpainted to provide a good "metal-to-metal" contact for the filter housing.

• Wiring Separation: Never bundle the "clean" wires (input side of the filter) with the "noisy" wires (output side). If they are run in the same duct, the filter’s effectiveness is bypassed due to inductive coupling.

• Cable Length: Keep the distance between the filter and the drive as short as possible. Long cables between these two components act as antennas and re-radiate noise.

• Heat Dissipation: Filters can become warm during operation. Ensure there is adequate clearance around the module for airflow and avoid mounting it near heat-sensitive components.

• Proper Sizing: Never use a filter with a current rating lower than the maximum input current of the drive. Under-sizing the filter can lead to overheating and potential fire hazards.
