Product Description
The Allen-Bradley 20G24NC367JA0NNNNN PowerFlex 755TS motor control drive is a digital drive accepting either AC or DC input. It supports 540V DC input with pre-charge, and either 400V 3-phase AC (full rated output: 367A continuous current, 200kW normal duty, 160kW heavy duty) or 400V single-phase AC (derated output: 170A, 90kW). This Size 6 drive weighs approximately 105 lbs and measures 665 x 308 x 208.4 mm, requiring 346.4 mm of rear clearance. It mounts vertically, needing a flat surface and operates optimally between -4 and 122F (derated operation up to 140F), requiring 504 CFM airflow. Storage temperature ranges from -40 to 158F. While lacking a built-in HMI, it features a digital display and keypad for monitoring and adjustments. Installation should be performed by trained professionals to avoid errors and ensure optimal performance.
Is Your Device Showing These Signs?
The Allen-Bradley 20G24NC367JA0NNNNN PowerFlex 755 AC drive commonly experiences issues related to IGBT failures, often indicated by fault codes and stemming from overcurrent events or thermal stress. Capacitor bank degradation, leading to DC bus undervoltage faults and reduced drive performance, is another frequent problem. Communication errors on the EtherNet/IP network, traced to firmware incompatibilities or network configuration problems, require troubleshooting. Encoder feedback issues, causing erratic motor control and speed regulation problems, demand encoder replacement or wiring inspection. Parameter corruption within the drive's memory necessitates a firmware re-flash and parameter reconfiguration.
