Product Description:
The 8BVI0055HWDS.000-3 is a high-performing inverter module. It is built by B & R Automation for industrial drive control. The module is appropriate for both compact and high-demand installations. This model is from the 8BVI Servo Controllers series.
The 8BVI0055HWDS.000-3 has a rated continuous power of 5.5 kW. It produces 7.6 Aeff continuous and 18.9 Aeff peak current. It includes a 330 µF DC bus capacitor to ensure reliable voltage handling. It uses 12 W of base power and requires 25 VDC ±1.6% input. A 500-mA electronic resettable fuse ensures fuse protection. The brake output delivers 24 VDC with 2.1 A current and 0.3 Ω resistance. It also provides 3 Ws of extinction energy and a maximum switching frequency of 0.5 Hz. Cable break, undervoltage, short circuit, and overload protection are all included as safety measures. The voltage rise rate meets the 10 kV/µs criterion. The cable length support is 25 m for 5/10 kHz and 10 m for 20 kHz. Enable inputs accept 24 VDC (up to 30 VDC) and draw 30 mA. Delay times are 20.5 ms for off and 100 µs for on transitions. Switching thresholds are LOW (less than 5 V) and HIGH (greater than 15 V). Electrical isolation is provided for all inputs. The maximum ground modulation allowed is ±38 V. The inverter operates at temperatures ranging from 5 to 40°C and can reach 55°C with derating. The relative humidity ranges from 5% to 85% during operation.
The B & R ‘s 8BVI0055HWDS.000-3 inverter is small and lightweight. The inverter switching frequency is fixed at 5 kHz and extends up to 20 kHz. The unit weights 2.6 kg. It has IP20 protection under EN 60529 and pollution level 2. The module meets IEC 60364's overvoltage category III requirements. It combines high performance and advanced security features.
Frequently Asked Questions about 8BVI0055HWDS.000-3:
Q: What is the benefit of using ±38 V ground modulation in 8BVI0055HWDS.000-3?
A: It helps maintain signal stability in environments with fluctuating ground potential. This prevents misfiring or false triggers during high-speed operations.
Q: How does fuse protection enhance the safety of 8BVI0055HWDS.000-3?
A: The 500 mA slow-blow electronic fuse protects circuits from overloads. It automatically resets, ensuring minimal downtime during transient faults.
Q: Why does 8BVI0055HWDS.000-3 support multiple switching frequencies up to 20 kHz?
A: This allows users to match switching frequency with motor dynamics and reduce audible noise. It also optimizes thermal and performance efficiency in diverse applications.
Q: How does cable break monitoring improve system reliability in this module?
A: It detects disconnections or damage in the brake line and triggers a safety response. This prevents uncontrolled motor behavior or brake failure.
Q: What is the role of the 330 µF DC bus capacitor in 8BVI0055HWDS.000-3?
A: It stabilizes voltage during sudden load changes or ripple fluctuations. This enhances drive accuracy and protects components from voltage dips.
