Allen-Bradley 25C-D010N104, 25C-D013N104 and 25C-D017N104 are PowerFlex 527 variable-frequency AC drives for controlling three-phase induction motors in Logix-controlled machines. Installed in an electrical panel between the 380…480 V three-phase branch circuit and the motor, each drive varies motor voltage and frequency so the Logix controller can command axis speed, torque or basic position as part of the machine program.

Power entering 25C-D010N104, 25C-D013N104 and 25C-D017N104 is rectified onto the internal DC bus and switched by an IGBT inverter to the U/T1, V/T2 and W/T3 motor outputs. Motion commands, configuration, standard control data, CIP Safety data and diagnostics pass through the two embedded EtherNet/IP ports; four digital inputs, two isolated analog inputs, one analog output, two relay outputs and two opto outputs provide the hardwired signal path for local devices.

Configuration for 25C-D010N104, 25C-D013N104 and 25C-D017N104 is stored in the Logix controller and edited with Studio 5000 Logix Designer motion instructions, so the controller coordinates the speed or position command and can transfer the saved configuration to replacement hardware. An optional encoder card closes the velocity or position feedback loop when the machine requires feedback beyond the standard sensorless motor-control modes; model selection changes the available power stage and frame, not this controller-owned workflow.
