20AD027A3AYNACN0

The 20AD027A3AYNACN0 is a Rebuilt PowerFlex 70 AC Drive manufactured by Allen-Bradley. The Allen-Bradley 20AD027A3AYNACN0 AC Drive belongs to Series A PowerFlex 70 AC Drives. The Allen-Bradley 20AD027A3AYNACN0 AC Drive feature 27 Amps of current rating, 480 Volts AC voltage, 20 Horsepower of output, the ControlNet (coax) network type, a full numeric LCD interface module, and a standard control method. The Allen-Bradley 20AD027A3AYNACN0 AC Drive is enclosed in a NEMA Type 1 enclosure. The Allen-Bradley 20AD027A3AYNACN0 AC Drive is characterized with 3 rated current values, a continuous current rating, a 1-minute current rating, and finally a 3-second current rating. Practically, the 1-minute current rating is close to 110% of the constant current rating. The open-loop function resets the current limit back to the current short-term rating when in normal operating conditions. The current limit is lowered up to the continuous level when the open-loop function detects an overload.

The Allen-Bradley 20AD027A3AYNACN0 AC Drive is equipped with several filters which are meant to help in tuning the AC Drive, for instance, there is a low-pass filter that is used to transmit low frequencies and to attenuate high frequencies. The Allen-Bradley 20AD027A3AYNACN0 AC Drive also adjusts the torque current limit level depending on the values of the heatsink temperature. The Allen-Bradley 20AD027A3AYNACN0 AC Drive is subjected to some faults as a result of status within or outside the drive which generally affects the running of applications and the AC Drive itself. The conditions that cause drive faults are taken to be more critical, and when they happen the Allen-Bradley 20AD027A3AYNACN0 AC Drive’s operation should be discontinued.
