20AD040A3NYNACC0

The Allen-Bradley/Rockwell Automation 20AD040A3NYNACC0 is an adjustable speed drive with no feedback encoder. The drive is used with 3-phase induction motors since they are the most economical. However, the 20AD040A3NYNACC0 can be used with single-phase or synchronous motors. The drive is part of the Allen-Bradley/Rockwell Automation PowerFlex 70 drives with user-selectable speeds. Drives in this family are designed to provide functionality to industrial applications on a global scale. The 20AD040A3NYNACC0, as with other PowerFlex 70 drives, can be adjusted in terms of Sensorless Vector control, Volts per Hertz control, or Vector control, which enables the drive to accommodate a wide range of industrial applications.

The Allen-Bradley 20AD040A3NYNACC0 has a NEMA Type 1 enclosure rating which allows the drive to be mounted inside or outside of a control cabinet. Note that the conduit plate on the 20AD040A3NYNACC0 is removable to enhance the mounting process of the drive. The drive does not have an internal brake resistor but it has an IGBT brake. The IGBT functions by opening the current flow path once a voltage is applied to it. Additionally, the IGBT brake does not open until the rated amount of voltage is reached. The 20AD040A3NYNACC0 is interfaced with power and signal control devices through a terminal block. For communication purposes, the drive accommodates a ControlNet port that helps connect the 20AD040A3NYNACC0 with other devices on the industrial floor. The port accommodates a coaxial cable. The drive features EMC filtering capabilities. For monitoring and troubleshooting, the 20AD040A3NYNACC0 is shipped with a full numeric LCD which also makes it easy to program the drive’s parameters.
