Product Description
The Allen-Bradley 20G1AND186AA0NNNNN PowerFlex 755 AC drive regulates the speed of 3-Phase AC motors in factory and process automation applications like pumps, fans, and conveyors by adjusting the output frequency. Operating on 480VAC, it delivers a variable output voltage (0-480VAC) and frequency (0-325/590 Hz depending on carrier frequency), providing 186A/150HP in normal duty and 156A/125HP in heavy duty with 97.5% efficiency. Utilizing Sine coded PWM with adjustable carrier frequency and offering various stop modes and programmable acceleration/deceleration, it accepts motion commands via digital/analog inputs and features EtherNet/IP communication for advanced control, configuration, and Automatic Device Configuration (ADC). Its safe speed monitor enables safe operation during maintenance, DeviceLogix manages drive output, and proactive current limit is adjustable. It includes a factory-installed brake transistor and comes in an IP20/IP00, NEMA/UL Open enclosure, size 7 frame.
Is Your Device Showing These Signs?
The Allen Bradley 20G1AND186AA0NNNNN 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 errors on EtherNet/IP or other network interfaces are frequent, stemming from configuration mismatches or hardware faults within the communication module. Overcurrent trips and ground faults are also observed, often resulting from insulation breakdown in the motor or cabling, or due to misconfigured drive parameters. Firmware corruption necessitates a reflash, and cooling fan failures cause overheating and subsequent drive shutdown.
Technical specifications
The Allen-Bradley 20G1AND186AA0NNNNN PowerFlex 755 AC drive controls the speed of 3-Phase AC motors in industrial applications. It operates on 480VAC, outputting variable voltage and frequency to drive motors at up to 150HP (normal duty) with high efficiency. It uses Sine coded PWM, offers adjustable acceleration/deceleration and stop modes, and accepts motion commands via digital/analog inputs. It also features EtherNet/IP communication for advanced control and configuration, a safe speed monitor, DeviceLogix, adjustable current limit, a brake transistor, and comes in an open enclosure.
Our Repair Process for the
20G1AND186AA0NNNNN
Our repair process for the Allen Bradley 20G1AND186AA0NNNNN PowerFlex 755 AC drive begins with a comprehensive diagnostic evaluation to pinpoint the failure. This includes a thorough inspection of IGBTs, capacitors, encoder feedback systems, and communication modules to identify hardware faults. We then address DC bus undervoltage faults, communication errors, overcurrent trips, and ground faults through component replacement, parameter adjustments, and insulation testing. Firmware corruption is resolved via reflashing, and cooling fan failures are rectified with replacements to prevent overheating. Each repair concludes with rigorous testing under load to ensure the drive meets or exceeds original performance specifications, followed by a detailed report outlining the work performed and recommendations for preventative maintenance.
