Product Introduction
AMCI SMD23E2-130A-M12 is a NEMA 23 integrated stepper motor with a built-in drive and network interface. It connects directly to EtherNet/IP, Modbus TCP, or Profinet networks, reducing external wiring and discrete drive hardware.This unit supports 3.4 A/phase motor current, 24–48 V DC supply, and programmable resolution from 200 to 32,767 steps per revolution. The dual-port Ethernet interface supports DLR/IP and Profinet MRP topologies. Two programmable 5–24 V DC inputs handle home, limit, jog stop, E-stop, capture, or index functions.
Installation & Configuration Guide
Preparation — 10 min
- Verify model, serial number, and nameplate data.
- Confirm supply voltage is 24–48 V DC.
- Check Ethernet cable type and network topology.
- Back up existing PLC motion parameters.
- Confirm steps/rev, direction, and current limits before enabling motion.
Removal — 5–10 min
- Disconnect main power and verify 0 V at terminals.
- Label M12 connectors and Ethernet cables.
- Remove mounting hardware without forcing the shaft.
- Inspect connectors for bent pins or moisture.
Installation — 10 min
- Mount to a rigid NEMA 23 interface.
- Maintain at least 20% power supply current margin.
- Connect Ethernet to the primary port first.
- Route cables away from VFD outputs and high-noise lines.
- Ground the motor frame per panel standards.
Power-On & Test — 10 min
- Apply 24–48 V DC and verify LED status.
- Confirm IP address, node ID, and protocol selection.
- Run a low-speed jog test before full-speed motion.
- Verify home/limit input response.
- Monitor temperature after 15 minutes of operation.
Troubleshooting Quick Reference
| Symptom | Most Likely Cause | First Check |
|---|---|---|
| No power | Missing or incorrect DC supply | Measure 24–48 V DC at input |
| Motor stalls | Undersized current or overload | Verify 3.4 A/phase setting |
| Network fault | Wrong IP or protocol | Check EtherNet/IP/Modbus/Profinet config |
| Lost position | Excess acceleration or load | Reduce speed and verify steps/rev |
| Input not detected | Wrong voltage level | Confirm 5–24 V DC and 10 mA drive |
| Overheating | Poor mounting or high current | Check ambient temp and duty cycle |

FAQ
Is SMD23E2-130A-M12 the same as SMD23E2-130E-M12?
No. The “E” version typically includes an encoder. The “A” version usually does not. Verify with the nameplate before substitution.Can it run on 24 V DC only?
Yes. The specified supply range is 24–48 V DC. Lower voltage reduces available speed and torque margin.Does it support Profinet and EtherNet/IP at the same time?
The platform supports EtherNet/IP, Modbus TCP, and Profinet, but only one active protocol should be configured per application. Confirm in the device configuration tool.What happens if steps/rev are set incorrectly?
The motor will move the wrong distance per command. Always match steps/rev to the microstep setting and mechanical ratio.I received a unit with a different suffix. Can I still use it?
Not without verification. Suffix changes can affect encoder feedback, torque rating, connector type, or firmware. Send a nameplate photo before installation.What is the lead time?
In-stock units can ship within 1–7 business days. Special orders depend on current availability.Do you test before shipping?
Yes. Each unit undergoes incoming inspection, power-on self-test, communication handshake, I/O verification, and functional motion check under test conditions.
