Product Description
The 20G1AND302AN0NNNNN is a compact PowerFlex 755 adjustable frequency AC drive designed for AC motor speed control, energy efficiency, and motor protection. It accepts 480VAC 3-phase input (47-63 Hz) and provides a 0-480VAC 3-phase output, with normal duty ratings of 302A/250HP and heavy-duty ratings of 248A/200HP. Output frequency ranges from 0-325 Hz (2 kHz carrier) to 0-590 Hz (4 kHz carrier), with configurable carrier frequencies of 2 kHz, 8 kHz, and 12 kHz. It supports premiere integration with Studio 5000 Logix Designer for direct parameter access via Ethernet I/P (10/100 Mbps, linear topology, DLR option). Other communication protocols include CIP Motion, ControlNet, DeviceNet, RS485 DFI, PROFIBUS DP, Modbus/TCP, HVAC protocols, Bluetooth, CANopen, and LonWorks. Features include a 0.98 displacement power factor, pre-charge AC terminal option, predictive diagnostics, safe torque-off and safe speed monitor relays, up to 5 expansion slots, CE-certified EMC line filtering, pulse width modulation for accurate digital control, adjustable output motor voltage (0 to rated value), standard closed/open-loop control, multiple feedback interface options, and a floor-mounted IP20/00 enclosure (50C operating limit without de-rating). It weighs 96 kg and measures 430.0 x 881.5 x 207.9 mm.
Is Your Device Showing These Signs?
The Allen Bradley 20G1AND302AN0NNNNN PowerFlex 755 AC drive commonly experiences issues such as IGBT failures, DC bus capacitor degradation leading to over-voltage faults, and cooling fan malfunctions causing thermal overload trips. Communication errors on the EtherNet/IP network are frequent, stemming from incorrect IP address configurations or faulty network cables. Parameter corruption within the drive's memory necessitates firmware upgrades or parameter resets to factory defaults. Current sensor drift affects motor control accuracy, requiring recalibration or replacement of the current transducers.
