20BD034A0AYNACD0

The Allen Bradley 20BD034A0AYNACD0 is categorized as an adjustable-frequency AC drive within the PowerFlex 700 series. It is engineered to work with an input voltage of 480 V AC in a three-phase setup. This specific model can handle a continuous output current rating of 34 A, making it ideal for application with a rated motor power of 25 horsepower.

For installation, the drive provides a sizing guideline that recommends using it with a motor rated at up to 2:1, optimizing efficiency and performance in variable speed applications. It is capable of managing internal power losses estimated at around 102 Watts. The control accuracy of this model is specified at ±0.01%, ensuring precise operation with a response lag of 6.4 milliseconds.

Regarding electrical protection, the 20BD034A0AYNACD0 is designed to work with upstream protection devices rated at 125 A circuit breakers or 50 A motor circuit protectors. In terms of overload conditions, this drive can withstand short-time currents of up to 40.5 A for a duration of one minute. The DC bus levels are nominally rated at 648 volts, with under-voltage and over-voltage limits set at 305 V and 810 V respectively, ensuring stable performance under varying operational conditions.

Users can adjust the carrier frequency settings between 2 kHz and 10 kHz, providing flexibility to accommodate different motor types and operational demands. The drive's encoder feedback mechanism operates on a quadrature principle with a ±27° range for enhanced positional feedback. On the communication front, built-in ControlNet coax communication ensures effective integration into networked environments.

The braking mechanism is equipped with a brake IGBT only, optimizing the braking process without extra components. Overall, the drive comes equipped with extensive input/output capabilities, featuring 6 digital inputs, 3 digital outputs, 2 analog inputs, and 2 analog outputs for comprehensive control and monitoring options.
