20DD022A0EYNANNBN

Manufactured by Allen-Bradley, the 20DD022A0EYNANNBN drive is a PowerFlex 700S variable frequency AC drive. The unit features the IP 20 NEMA type 1 enclosure with a conformal coating, providing the drive and the internal components with protection from adverse atmospheric effects. The 20DD022A0EYNANNBN drive also comes with the IGBT brake and it has an adjustable Bus undervoltage trip. The part has an operating voltage rating of 400 Volts AC. It is a 3-phase AC drive with an input current of 11.5 Amps at an output voltage of 400 Volts AC. The drive delivers an increased performance thanks to its easy-to-use features. The PowerFlex 700S drives feature a digital current regulator that outperforms the older style analog regulators in terms of speed, repeatability, and drift. The unit also features a negative feed-forward for reducing or eliminating the overshoot during the speed changes. This feature allows the 20DD022A0EYNANNBN drive to prevent backup when the drive is braking.

The Allen-Bradley 20DD022A0EYNANNBN drive uses an advanced edge-to-edge algorithm and pulse position averaging for an extremely accurate speed measurement with an excellent performance at a very low speed. With the servo lock, the Allen-Bradley  20DD022A0EYNANNBN drive compensates for the lost position during the step loads to the velocity regulator. This ensures optimal performance. The 20DD022A0EYNANNBN drive is also built with the inertia adaptation that stabilizes the inertia disconnect as a result of flexible couplings. The unit also comes with an advanced process loop that executes six times faster compared to other loops. This ensures that the drive can deliver an improved dynamic response even in the tension control applications.
