20DC056A0EYNANASE

The 20DC056A0EYNANASE, manufactured by Rockwell Automation and part of the Allen-Bradley PowerFlex 700S line, is a versatile adjustable frequency AC drive. This unit is specifically configured to operate at a voltage level of 400V AC and is built to accommodate three-phase power systems. It can effectively manage a maximum input current of 56 amps. The drive features an IP20-rated enclosure, conforming to NEMA Type 1 standards. This allows it to function reliably in environments that do not have extreme levels of dust or moisture.

A quick start guide is provided, facilitating prompt installation and user orientation. The interface of this AC drive is presented with a blank cover, simplifying the design while maintaining its functionality. A notable feature of this drive is its IGBT brake system, which aids in managing motor dynamics during operation.

Safety mechanisms like an adjustable bus undervoltage trip add to its reliability, allowing users to set parameters that suit their needs. The drive's performance is closely monitored, with a thermistor in the heat sink that is checked by an onboard microprocessor to prevent overheating conditions.

This model also incorporates a logic control ride-thru feature, permitting it to maintain operational stability for a duration of 0.25 seconds when the drive is not actively running. Additionally, it has a power ride-thru capability that lasts 15 milliseconds at full load, ensuring the system can handle brief power interruptions without failure.
