Key Features

1. Closed-Loop Feedback: Core speed/torque feedback for GV3000 vector control

2. Signal Conditioning: Amplifies, filters, and isolates feedback signals

3. Fault Detection: Monitors feedback health and reports to main control

4. Precision Calibration: Four potentiometers for fine-tuning feedback accuracy

5. 3U Rack Compatibility: Interchangeable in GV3000 3U enclosures.

Application

• Drive Systems: Reliance GV3000 (5–200 HP, 230/460/575 VAC) AC drives

• Control Modes: Closed-loop vector (flux-vector), V/Hz with feedback

• Industries: Conveyors, extruders, machine tools, material handling, pumps/fans requiring precise speed control

• Function: Motor feedback processing for accurate speed regulation.

Compatibility

• Compatible Drives: GV3000 (5–200 HP, 230/460/575 VAC)

• Rack: Standard 3U GV3000 drive rack

• Peripherals: 0-55329-7 main control board, 0-55325-x gate driver boards.

Critical Notes

• Distinction: 0-55350-x = feedback boards (motor signal processing); 0-55329-x = main control; 0-55325-x = gate drivers.

• Replacement: No direct substitute; refurbished units with full signal testing are standard.

• Availability: Limited stock; lead times 2–4 weeks; warranty options available.

• Revision Note: "15E" denotes a specific hardware revision; ensure revision compatibility for replacement.
