Product Introduction
Siemens A5E36717788 is an IGD3/R2 board for Sinamics drive systems. Siemens support identifies it as an IGD3/R2 board rated for 480 V / 650 V DC and 840 A.
This is a drive-side board, so exact system compatibility matters. Match the drive family, voltage class, and board revision before ordering, because the wrong board can create a clean-looking but dead cabinet.industry.
Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to This Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Drive will not enable | Board fault or missing DC supply | ✅ High | Measure DC bus voltage and check fault code | Verify supply before replacing the board |
| Immediate fault at power-up | Revision mismatch or failed board | ✅ High | Compare part number and board labeling | Confirm exact Siemens match first |
| Motor does not respond | Control path problem or gate-drive issue | ✅ High | Check command signal, interlocks, and diagnostics | Inspect upstream control and interface wiring |
| Intermittent operation | Loose connector or thermal issue | ✅ High | Reseat connectors and inspect for heat marks | Check contact integrity and cooling |
| Overcurrent trip | Downstream motor or power stage fault | ✅ Medium | Test the motor and cabling separately | Do not replace the board until the load is cleared |
| No communication with host | Protocol or interface mismatch | ✅ Medium | Verify drive network settings and cabling | Check the network side before condemning hardware |
If you are stuck, contact technical support with photos, fault codes, and the drive nameplate details.

Frequently Asked Questions (FAQ)
Q: What is Siemens A5E36717788?
A: It is an IGD3/R2 board used in Siemens Sinamics drive systems.industry.
Q: Is this a controller or a power board?
A: It is a drive board, not a general PLC CPU.
Q: What voltage and current ratings apply?
A: Public Siemens support data lists 480 V / 650 V DC and 840 A.industry.
Q: Can I replace it by matching only the part number?
A: Not safely. You still need to verify the exact drive family, voltage class, and board revision.industry.
Q: Is it new original or refurbished?
A: The market shows new condition listings, but you should only state the condition you can document.
Q: Why does this board matter so much?
A: It sits in the drive path, so a mismatch can prevent the inverter from starting or make the cabinet fault immediately.industry.
Q: What should I check before ordering?
A: Confirm the drive model, DC rating, board label, and any existing fault history before you buy.
