20AD022A3AYNADNN

The Allen-Bradley/Rockwell Automation 20AD022A3AYNADNN is an AC drive with a user-adjustable frequency. The drive has a size D frame and a current rating of 22 Amps. The 20AD022A3AYNADNN sends and receives communications through a DeviceNet communication slot which supports a DeviceNet network. The communication speed on this type of network is dictated by the distance between communicating devices. For example, a 500-meter network length will have a communication speed of 125 Kilobytes per second while a 100-meter network length will have a communication speed of 500 Kilobytes per second. Additionally, a DeviceNet network supports a maximum of 64 nodes.

The 20AD022A3AYNADNN has an internal brake IGBT but no internal brake resistor. The drive accommodates standard control and it belongs to the standard emission class. When installing the 20AD022A3AYNADNN, grounding must be provided. A single safety ground point must be used with the point being directly connected to the building’s steel structural components. The 480 Volts AC power supply and the other devices interfaced with the 20AD022A3AYNADNN should be grounded individually but directly on the safety ground point. The Allen-Bradley 20AD022A3AYNADNN provides a shield terminal where the shield for the motor cable is connected. The other end of the motor shield cable is connected to the motor frame. Although grounding for all the cables is recommended, the signal and control wiring using a shielded cable, the grounding should only be done on the source end only and not on the drive. Note that high ground leakage currents may occur if an RFI filter is used.
