4. Product Introduction
The IC800SSD104RS1 is a GE Fanuc S2K Series standalone servo amplifier designed for precise motion control of S-Series and MTR Series brushless servo motors. It accepts 115/230 VAC input and delivers 4.3 A continuous output with resolver feedback for commutation and closed-loop control.
The drive supports multiple command formats including pulse and direction, quadrature encoder, and analog velocity/torque commands. It features sinusoidal commutation for smooth low-speed performance, a two-character diagnostic LED, and an RS-232 port for configuration and monitoring. Power and motor connections are located on the bottom of the unit to help isolate electrical noise. The amplifier must be mounted vertically to allow proper airflow through the heatsink.

5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No power / dead unit | Missing AC input or internal fuse | ✅ High | Measure 115/230 VAC at input terminals | Verify supply voltage and fusing |
| Drive faults immediately | Feedback cable, motor wiring, or overcurrent | ✅ High | Check resolver cable continuity and motor connections | Inspect feedback and power wiring; clear fault |
| Motor does not turn | Enable signal missing or wrong mode | ✅ High | Verify enable input and selected control mode | Confirm enable logic and command source |
| Erratic motion or vibration | Incorrect tuning or resolver mismatch | ⚠️ Medium | Check resolver wiring and tuning parameters | Re-tune or verify motor/drive matching |
| Overtemperature fault | Inadequate cooling or high ambient | ✅ High | Confirm vertical mounting and cabinet airflow | Improve ventilation; reduce load if necessary |
| Cannot communicate via RS-232 | Baud rate, cable, or port issue | ⚠️ Medium | Verify 9600 baud and correct null-modem cable | Use proper serial cable and settings |
If input power, feedback, and enable signals are correct and the drive still faults, replace the IC800SSD104RS1. Always follow lockout/tagout and ESD procedures when working on the unit.
6. Frequently Asked Questions (FAQ)
Q: What is the continuous current rating of the IC800SSD104RS1? A: 4.3 A.
Q: What input voltage does it accept? A: 115 VAC or 230 VAC.
Q: What type of feedback does it use? A: Resolver feedback. It is intended for use with GE Fanuc S-Series / MTR Series motors that have resolvers.
Q: Is this a complete motion controller or just an amplifier? A: It is a standalone servo amplifier/drive. It can operate with external command signals (pulse/direction, analog, etc.) and includes basic I/O and diagnostics.
Q: Is the IC800SSD104RS1 still in production? A: No. The S2K Series has been discontinued by the manufacturer. Remaining units are new surplus or refurbished. Condition is clearly stated as New Original / New Surplus.
Q: Why is a new-surplus IC800SSD104RS1 often priced lower than current servo drives? A: It is an end-of-life product. New-surplus stock comes from project overstock, is tested, and is sold at a reduced price while still carrying warranty.
Q: How must the drive be mounted? A: Vertically, to ensure proper convection cooling through the heatsink. Horizontal mounting can lead to overheating.
