Allen-Bradley D8P0A0AYNNNNN PowerFlex70 AC Drive Unit

Module Feature

D8P0A0AYNNNNN belongs to PowerFlex70 high-performance AC drive manufactured by Allen-Bradley (Rockwell Automation). Rated output current 8A,5HP normal duty /3HP heavy duty,380~480V three phase input. It supports V/Hz, sensorless vector and FORCE vector control,optional encoder feedback for high precision speed/torque regulation. Integrated brake IGBT,standard IP20 panel mount housing,blank front plate without HIM keypad. Reserved DPI expansion slot for optional communication adapters such as DeviceNet,ControlNet and EtherNet/IP. Widely used for small extruders,packaging machines,small conveyors and general factory automation equipment.

Working principle

Three-phase AC mains power is rectified into DC bus voltage. IGBT power stage outputs adjustable voltage and frequency PWM waveform to control induction motor speed and torque. FORCE vector algorithm provides high starting torque across wide operating range. Built-in braking IGBT consumes regenerative energy generated by motor deceleration; external brake resistor must be matched and wired separately. The drive continuously monitors DC bus voltage,output current and internal temperature for protection.
