Product Description
The Allen-Bradley 20BC085A0ANNACC0 PowerFlex 700 AC drive is a high-performance, ready-to-use variable frequency drive for controlling 3-phase AC induction motors in various speed-sensitive applications. It features a CE standard EMC filter with a built-in DC bus choke to minimize harmonic distortion and transformer heating, operates at 400VAC with a nominal current of 85A, and delivers 45kW of power. The drive includes overload and over-temperature protection, utilizes PWM technology for reduced motor heating and noise, offers adjustable 3-phase output voltage, and provides enhanced sensorless vector control with 0.1% speed regulation over a 120:1 range. Integrated with a ControlNet adapter for seamless factory integration and data transfer, it comes in a NEMA-rated enclosure for panel mounting, operates between 0-50C, weighs 24.29 kg, and measures approximately 220 x 758.8 x 201.7 mm.
Is Your Device Showing These Signs?
The Allen Bradley 20BC085A0ANNACC0 AC drive commonly experiences issues related to IGBT failures, often indicated by overcurrent faults or drive trips. Resolving these faults requires replacing the faulty IGBT module and thoroughly inspecting gate driver circuitry for damage. Capacitor degradation within the DC bus section is another frequent problem, leading to voltage sags and performance instability; capacitor replacement restores proper DC link voltage. Communication errors on the EtherNet/IP network also occur, stemming from cabling issues, incorrect IP address configurations, or firmware incompatibility; verify network settings, cable integrity, and update firmware to ensure seamless communication.
