20AB4P2A2AYNNNNN

The 20AB4P2A2AYNNNNN is a 240 Volts AC adjustable frequency drive from Allen-Bradley. The drive has some of its internal components negatively affected by electrostatic charges. The 20AB4P2A2AYNNNNN, as with other drives in the PowerFlex 70 series, comes with THE DC bus common mode capacitors referenced to the ground by default. The common mode capacitors should remain connected when the drive is powered from either a solidly grounded AC source or DC source from a passive rectifier which has an AC source and a solid ground. Leaving the common mode capacitors connected under these power sources ensures that the 20AB4P2A2AYNNNNN meets the requirements specified by the Underwriters Laboratories, it minimizes the electrical noise, and it enables the drive to have a stable operation.

Additionally, these connections assist in EMC compliance and minimize voltage stress on motor bearings and other components. However, with 20AB4P2A2AYNNNNN and other PowerFlex 70 drives, the common mode capacitors should be disconnected if the drive’s power supply is not solidly grounded, it is impedance grounded, it is B-phase grounded with a high resistive ground, when its DC voltage is fed from an active converter, and when a regenerative unit is used such as a common DC bus supply. The Allen-Bradley 20AB4P2A2AYNNNNN uses standard control for its I/O. The drive does not have an onboard dedicated communications slot. The 20AB4P2A2AYNNNNN does not require a feedback encoder. For the emissions class, the adjustable frequency drive belongs to the unfiltered class. The drive is shipped with an English manual to make the installation and troubleshooting procedures easy. The 20AB4P2A2AYNNNNN has an amperage of 4.2 Amps and it has a type A frame.
