  • I/O Terminal Block: Isolated digital inputs/outputs (drive enable, fault, interlock)

  • LEDs:

    • PWR (green): On = +5V OK

    • ACT (green): Blinking = resolver signal activity

  • Power: +5V, ±12V, GND

  • Data: 14-bit position/speed data to UDC via fiber

  • Control: I/O status, fault reset, fiber communication

Core Functions

1. 14-bit Resolver Signal Conditioning: Generates 2kHz excitation; amplifies/filters sine/cosine signals; converts to high-resolution digital position/speed data.

2. Closed-Loop Speed/Position Feedback: Provides 14-bit precision for high-accuracy motor control (critical for metal rolling, paper machines).

3. Isolated Driver I/O: Interfaces drive control signals with external systems; isolates high-voltage power from low-voltage logic.

4. Fault Detection & Reporting: Monitors resolver signal loss, phase error, or overload; triggers FLT LED and drive shutdown.

5. Fiber Optic Communication: Transmits 14-bit data to UDC via fiber (10Mbps, Manchester encoding) for noise immunity in DPS.

Applications

• AutoMax SA 3000/SA 3100 Drives: High-power AC/DC drives for metal rolling, paper machines, extruders, cranes, conveyors (DPS systems).

• Harsh Environment Motion Control: High vibration, dust, or moisture conditions (resolvers more robust than encoders).

• Legacy System Maintenance: Replacement for failed 0-60031-4 modules to restore 14-bit closed-loop control without full upgrade.

• Precision Speed Regulation: Lines requiring tight speed/position accuracy (web processing, coil winding).

Usage & Maintenance

Installation

• Power OFF only: Insert into designated SA 3000/SA 3100 rack slot; secure with front-panel screws. No hot-swap.

• Wire resolver to 9-pin D-sub; connect I/O to terminal block per Reliance pinout.

Configuration

• Set drive parameters for 14-bit resolver feedback (excitation frequency, pole pairs) via keypad/software.

• Calibrate resolver offset for accurate position tracking.

Routine Maintenance

• Every 3–6 months: Power off; clean dust from connectors/PCB; check resolver cable for damage.

• Verify LEDs: PWR ON, ACT blinking during normal operation.

Troubleshooting

• No speed feedback: Check resolver wiring, excitation voltage, and D-sub connections.

• FLT LED ON: Inspect resolver cable for shorts; verify signal amplitude; check for EMI.

• Intermittent errors: Clean D-sub contacts; use shielded resolver cable; relocate away from high-voltage cables.

Storage & Shipping

• Store in anti-static bag at -20–70°C, dry/dust-free.

• Ship with cushioning; avoid bending PCB or damaging D-sub/terminal block.
