Processor 32-bit DSP plus FPGA logic. Memory 16 MB Flash and 2 MB SRAM. Supply 24 V DC from drive or exciter rack. Power consumption 5 to 8 W. Analog input accuracy plus minus 0.05 percent. Digital inputs 8 configurable, digital outputs 8 configurable, analog inputs 4, analog outputs 2. Communication RS-422, Modbus RTU, CANopen, optional Ethernet. Control modes DTC motor control, AVR with PID, manual excitation with PI, PSS, reactive power or power factor control. Isolation 1500 V AC I/O to power. Operating temperature -25 to plus 70 C. Dimensions about 288 mm by 112 mm by 54 mm. Protection IP20. Certifications CE, UL, cUL, CSA, ATEX context dependent.

Real-time DTC torque control and IGBT firing in ACS800 or 880. Generator AVR, field current limiter, stator current limiter, loss-of-excitation protection, rotor temperature monitoring, thyristor conduction check. Three-level supervision alarm, redundant switch, instantaneous trip.

ACS800 and ACS880 0.5 to 5 MW motor drives. UNITROL 5000 or 6000 generator excitation in thermal hydro and gas turbine plants.

Multi-layer PCB, DSP and FPGA, SDRAM and Flash, fiber sync header, plug-in backplane connector, LED row, aluminum heat tab.

In drive mode samples motor current voltage, runs DTC flux and torque estimator, emits IGBT gate pattern over fiber. In excitation mode measures generator terminal voltage and field current, computes AVR error, drives thyristor bridge firing angle, applies PSS damping.

Seat in ACS800 DCU slot or UNITROL rack, align backplane, 24 V DC isolated supply, redundant pair needs identical firmware.

XVC724BE102 is BE high-end variant, not interchangeable with AE101 entry version without re-licensing. Hot-swap only in redundant ACS880 configuration.
