Product Description
The Allen-Bradley/Rockwell Automation 20G1AND156JA0NNNNN PowerFlex 755 variable speed drive is a 156 Amp unit designed for 460VAC motors, operating on input voltages between 342VAC and 528VAC. It features an internal transistor, a pre-installed filter and jumper for common mode cap connection, and certifications including Australian Communications, Media Authority, American Bureau of Shipping, EAC, CE, and Functional Safety. The drive supports autotune parameters like IR voltage drop (Parameter 73), Ixo voltage drop (Parameter 74), Flux current reference (Parameter 75), total inertia (Parameter 76), and inertia test limit (Parameter 77). It also performs inertia tests to determine load acceleration time, triggering an autotune inertia fault if the inertia test limit is exceeded.
Is Your Device Showing These Signs?
The Allen Bradley 20G1AND156JA0NNNNN PowerFlex 755 AC drive commonly experiences issues such as IGBT failures, capacitor degradation leading to DC bus undervoltage faults, and encoder feedback problems causing erratic motor control. Communication faults on the EtherNet/IP network are also frequent, stemming from firmware corruption or hardware damage to the communication module. Overcurrent trips and ground faults are addressed through inspection and replacement of power components, while resolving parameter corruption requires a firmware reload and careful configuration. Repair procedures include thorough testing of gate drivers, DC bus components, and network interfaces to ensure optimal performance and reliability.
