Product Overview

The Danfoss 132L6120 (IC2-30FA3N04-07A2E20F4+ACBC) is a high-efficiency frequency converter from the iC2-30 series, specifically designed for air-cooled motor control in industrial environments. This 3 kW unit provides precise speed and torque regulation for three-phase motors operating on 380-480 VAC supplies. By incorporating an integrated brake chopper, the drive is optimized for applications requiring rapid deceleration or dynamic braking, effectively preventing over-voltage trips during mechanical braking cycles. It stands as a reliable solution for minimizing system downtime in demanding automated processes such as machine tools and conveyor systems.

Technical Specifications

Frequently Asked Questions

Does the integrated brake chopper include a braking resistor?

No, the internal brake chopper provides the switching circuitry and logic required to manage braking. A suitably sized external braking resistor must be connected to the dedicated terminals to absorb the regenerated energy.

Can this drive be used in a C4-rated environment without further shielding?

The unit meets C4 category requirements for emissions. However, the final installation must still adhere to proper grounding and shielded cabling practices to ensure the entire drive system complies with EMC regulations in industrial locations.

Is this unit suitable for mounting outside of a control panel?

No, the IP20 enclosure is not protected against dust, moisture, or accidental contact. It must be housed within an enclosure that meets the environmental requirements of the installation site.

Engineering Guidelines and Installation Best Practices

• Braking Resistor Selection: When sizing the external braking resistor for the +ACBC configuration, ensure the resistance value is within the manufacturer's specified minimum range for the 3 kW frame size. Verify that the resistor wattage is sufficient for the intended braking duty cycle to prevent thermal overloading.
• Thermal Management: The 3 kW rating assumes effective airflow. Maintain a clear vertical clearance of at least 150 mm around the drive to allow for proper heat dissipation. If the cabinet environment exceeds 50 deg C, current de-rating will be required to maintain operational reliability.
• Grounding for EMC: To maintain C4 compliance, connect the motor cable shield to the chassis using a 360-degree clamp at both the motor and the drive end. Ensure the cabinet backplate has a high-conductivity, low-impedance ground connection to the main earth bus.
