20AD8P0A0AYNNRNN

The 20AD8P0A0AYNNRNN is an adjustable frequency drive designed and manufactured by Allen-Bradley/Rockwell Automation. Note that a feedback encoder is not applicable to this drive. The 20AD8P0A0AYNNRNN accepts standard control for its I/O. The drive has RIO (remote I/O) network configured port. Devices utilizing a Remote I/O network are synchronized to the scan rate of the Central Processing Unit (CPU) and each device’s configurations are interfaced with the PLC’s CPU. This interconnection of devices on the network considers remote devices as extensions. However, the RIO network has a few disadvantages. It is proprietary, it is a closed system, it does not support all of the devices, and it has a limit to the number of devices that can be connected. The 20AD8P0A0AYNNRNN has a brake IGBT but does not feature an internal brake resistor.

The braking circuitry is necessary when the 20AD8P0A0AYNNRNN is used in applications that have a high rate of stopping and or changing directions. This includes hoists, centrifuges, and conveyors. The drive is part of the PowerFlex 70 drives supporting adjustable frequency. Drives in this family are affected by high temperatures and extremely high humidity levels. Therefore, to keep the 20AD8P0A0AYNNRNN and all the drives in the PowerFlex family operating as required, the temperature and humidity should be controlled. For example, the drive should not be operated in industrial environments with a non-condensing relative humidity level of less than 5% or one that exceeds 95%. For the temperature, requirements like mounting clearances and proper ventilation should be observed. The 20AD8P0A0AYNNRNN is shipped with a human-machine interface module.
