20AD040A3AYNAEC0

The 20AD040A3AYNAEC0 is a variable frequency drive from Allen-Bradley/Rockwell Automation. The drive has no pre-installed feedback encoder. The 20AD040A3AYNAEC0 falls under the PowerFlex 70 family of drives. Drives in this family provide compact power, operator, and control modules. Additionally, the 20AD040A3AYNAEC0, like with other drives in the same family, is reliable and simple to use, and it saves on panel space and it is relatively easy to configure. With an IP20 ingress protection rating, the 20AD040A3AYNAEC0 is not protected against liquids. The drive is designed to accept an alternating current (480 Volts AC) supplied by a 3-phase power source.

The Allen-Bradley 20AD040A3AYNAEC0 uses an LCD to indicate a fault. In case of a fault, the “faulted” message appears on the status line. Additionally, the display indicates the fault number, the fault name, and the amount of elapsed time since the occurrence of the fault. The LCD also shows an alarm by displaying the alarm name and by graphically showing an alarm bell. The 20AD040A3AYNAEC0 supports the use of the ESC key on its alphanumeric keypad to regain control of the drive when a fault or an alarm is displayed. After manually diagnosing and correcting the fault, the fault can be cleared by pressing the stop button, cycling the drive power, setting parameter 240 to “1” or by pressing the “clear faults” button on the human-machine interface module. The Rockwell Automation 20AD040A3AYNAEC0 has its current rated at 40 Amps. The drive has an EtherNet-IP communication port to connect it to the wider industrial network. The 20AD040A3AYNAEC0 is affected by extremely high ambient temperatures (above 50 degrees Celsius).
