The Allen-Bradley 20BD-DB1-1 is a brake resistor kit designed for use with the PowerFlex 700 AC drive. It is an internal component that provides a braking function to the motor, which is particularly useful in applications where the motor needs to be stopped quickly or in situations where the motor may not be able to stop on its own due to load or other factors.
Technical Specifications
The brake resistor kit has a resistance of 115 ohms at 5% duty cycle, and it operates at a voltage range of 400/480V. This kit is designed for use with the PowerFlex 700 AC drive, which is a high-performance adjustable frequency AC drive that is suitable for a wide range of industrial applications.
Alarm/Error Codes
The PowerFlex 700 AC drive, which the brake resistor kit is designed for, has a comprehensive system for reporting faults and errors. The drive can detect various faults and errors, such as motor overload, overvoltage, and undervoltage, and it can also detect issues with the drive itself, such as overheating or communication errors. The drive provides detailed information about the faults and errors through its LCD display and through communication protocols like Modbus and DeviceNet.
