Product Description:
The 8BVI0028HWD0.000-3 controller is from the series of 8BVI Servo Controllers. It is a compact and efficient servo controller. The switching frequency is set at 5 kHz and can be adjusted up to 20 kHz. Designed to handle stringent motion control requirements. It provides consistent performance and safety protection.
The 8BVI0028HWD0.000-3 is manufactured by B & R Automation. It has a constant power output of 2.8 kW. The device can handle a steady current of 3.8 Aeff and a peak of 9.5 Aeff. It has a nominal DC bus voltage of 800 VDC and can run safely up to 900 VDC. The integrated DC bus capacitance measures 165 µF. The rated voltage for a 24 VDC power supply is 25 VDC with a tolerance of ±1.6%. The maximum power consumption is 12 W. The motor has a brake output voltage of 24 VDC. The brake current reaches 2.1 A continuously with an internal resistance of 0.3 ohms. The switching frequency is 5 kHz and can be adjusted up to 20 kHz. The maximum brake overcurrent is 10 A and the switching frequency is 0.5 Hz. It also detects cable damage on the braking line. The input is electrically separated and overvoltage protected to ±38 volts. The unit can work in ambient temperatures ranging from +5°C to +40°C, and up to +55°C with derating. It can be installed at elevations of up to 4000 meters. Derating begins at 500 meters altitude and imposes a current reduction of 0.38 Aeff per 1000 meters.
The 8BVI0028HWD0.000-3 Servo is compatible with termination cables ranging in diameter from 12 to 22 mm. The connection range is 0.25 - 4 mm² flexible. It weights is approximately 2.6 kg. It can be stored at temperatures of -25°C to +55°C and transported at temperatures as high as +70°C. The Servo is UL and CSA listed.
Frequently Asked Questions about 8BVI0028HWD0.000-3:
Q: How does the adjustable switching frequency benefit the 8BVI0028HWD0.000-3?
A: The selectable switching frequencies of 5/10/20 kHz allow optimization for noise reduction or performance. It enables tailored control based on application requirements.
Q: Why is input isolation important in the 8BVI0028HWD0.000-3 servo controller?
A: Input isolation helps prevent electrical interference and protects internal circuits. This ensures stable and reliable operation in noisy environments.
Q: How does the 8BVI0028HWD0.000-3 ensure safety at high altitude installations?
A: It includes automatic current derating above 500 m altitude. This protects the system from thermal overload and voltage stress in thinner air.
Q: Why does 8BVI0028HWD0.000-3 use slow-blow fuse protection?
A: Slow-blow fuses tolerate brief current surges without tripping. This prevents unnecessary shutdowns during peak loads or startup.
Q: What does the IP20 protection rating of 8BVI0028HWD0.000-3 mean?
A: IP20 protects against solid objects larger than 12 mm but not moisture. It is suitable for control cabinets in clean industrial environments.
