Key Features

• Dual control modes: Isochronous (zero droop) for constant-speed standalone operation; droop control for grid parallel and load sharing.

• High accuracy: Speed regulation ±0.25% with adaptive PID tuning.

• Flexible setpoint: Remote control via 4–20 mA / 1–5 VDC analog signals.

• Integrated protection: Independent overspeed logic, critical speed avoidance, soft start, valve position limiting, 15 fault shutdown + 15 alarm inputs, first-out fault memory.

• Communications: RS-232/RS-485 with Modbus RTU/ASCII; password-protected parameters.

• Highly integrated: Works with Woodward actuators, I/O modules, and generator controllers for full-system control.
