The PowerFlex 700 model 20BD011A3AYNADN0 is an adjustable-frequency AC drive manufactured by Allen Bradley, designed to provide versatile motor control. It is configured to operate at a nominal motor voltage of 460 V, with support for a range between 380 V and 480 V. This unit is powered by a three-phase input supply of 480 V AC at a frequency of 60 Hz, making it suitable for various industrial applications that require energy-efficient motor operations.
This drive features a nominal DC bus voltage of 648 V, with defined low and high trip settings at 305 V DC and 810 V DC, respectively. To protect the system, input undervoltage and overvoltage thresholds are established at 280 V AC and 570 V AC. The continuous output current is rated at 11 A, with the capacity to handle short-duration peaks of 12.1 A for one minute and up to 16.5 A for three seconds, offering robustness during variable load conditions.
The carrier frequency for this drive can be adjusted between 2 kHz to 10 kHz but is rated for 4 kHz under normal operating conditions. Additionally, IGBT technology is incorporated for dynamic braking, enhancing the drive's ability to control motor deceleration effectively.
For connectivity and integration within control networks, the 20BD011A3AYNADN0 is DeviceNet enabled, facilitating smooth communication with other devices in an automation environment. Regarding I/O capabilities, this drive supports 6 digital inputs, 3 digital outputs, and 2 analog inputs, allowing for comprehensive monitoring and command functionalities in process control.
