- Automated assembly lines
System Compatibility
The SMCM4-AI is compatible with the following system configurations:
- PLC brands: Siemens S7 series, Mitsubishi FX/Q series, Omron CP/CJ series, Delta DVP series, Schneider Modicon
- CNC controllers: Fanuc 0i/21i, Siemens 828D/840D, Mitsubishi M70/M80, GSK, KND
- Motor types: SERVOLAND DC servo motors (matched series); verify winding voltage and encoder resolution
- Feedback devices: Incremental encoders (2500 PPR typical); absolute encoder support — verify model variant
Selection Guide
Use the following criteria to confirm the SMCM4-AI is the right drive for your application:
- Step 1 — Confirm drive type: Verify your system uses a DC servo drive (not AC servo). Check motor nameplate for DC voltage rating.
- Step 2 — Match power rating: Confirm the drive’s continuous and peak current rating matches your motor’s requirements.
- Step 3 — Verify command interface: SMCM4-AI uses analog input (AI). If your controller outputs pulse/direction, consider the SMCM4-PI variant.
- Step 4 — Check encoder type: Confirm encoder resolution and signal type (differential TTL) match the drive’s feedback input.
- Step 5 — Review protection requirements: Ensure the drive’s built-in protections (OC, OV, OT) meet your installation environment standards.
- Step 6 — Replacement scenario: If replacing a failed unit, photograph the original wiring and parameter settings before removal.

Replacement & Compatibility FAQ
Q: Can the SMCM4-AI replace my existing servo drive from a different brand?
A: Possibly, but cross-brand replacement requires careful verification of voltage, current, encoder interface, and command signal type. Contact us with your original drive model for a compatibility assessment.
Q: What is the difference between SMCM4-AI and SMCM4-PI?
A: The AI variant accepts analog ±10V command signals; the PI variant accepts pulse & direction signals. Choose based on your controller’s output type.
Q: Do you supply the matching SERVOLAND servo motor?
A: Yes. Contact us with your required motor specifications (torque, speed, shaft size) and we will recommend the matched motor model.
Q: Is a warranty provided for replacement units?
A: Yes — 12 months from shipment date. DOA (Dead on Arrival) units are replaced within 30 days, no questions asked.
Q: Can I get a datasheet or wiring diagram?
A: Yes. Email support@konmask.com with your model number and we will provide available documentation.
