Engineering Advantages
- High-resolution microstepping — reduces resonance and audible noise versus full/half-step operation, enabling smoother motion profiles at low speeds.
- RORZE ecosystem compatibility — designed to interface natively with RORZE controllers and motion cards, minimising integration risk in existing machine architectures.
- Compact form factor — space-efficient design suited for dense control cabinet layouts common in semiconductor fab tooling.
- Robust protection circuitry — built-in overcurrent and thermal shutdown safeguards extend MTBF and protect downstream motor windings.
- Stable current control — constant-current chopper drive maintains torque consistency across the full speed range.
System Architecture & Signal Flow
The RD-323MS operates within a standard open-loop stepper drive architecture:
- Motion Controller / PLC — generates STEP pulse train and DIR signal (TTL/optocoupled).
- RD-323MS Driver — receives STEP/DIR, applies microstepping current waveforms to motor phases A and B.
- Stepper Motor — converts electrical phase excitation into precise angular displacement.
- Mechanical Load — lead screw, belt drive, or direct-coupled stage.
For closed-loop configurations, pair with a RORZE encoder feedback card or an external motion controller supporting encoder correction.

Technical FAQ
Q: Is the RD-323MS compatible with third-party stepper motors?
A: Yes, provided the motor’s phase current and voltage ratings fall within the driver’s output specifications. Consult the datasheet or contact us for motor matching guidance.
Q: Can I use this driver as a direct replacement for another brand’s driver?
A: In many cases yes, if the STEP/DIR interface and power supply voltage are compatible. We recommend bench-testing before full machine integration.
Q: Do you provide the original RORZE datasheet?
A: Yes. Request the technical document via email and we will supply it with your order confirmation.
Q: What warranty applies?
A: New units carry the standard Konmask 90-day DOA warranty. Surplus/refurbished units are sold as-is with inspection report. Extended warranty available on request.
Q: Can you supply multiple units for a production line retrofit?
A: Yes. Contact us for volume availability and lead time. We support both spot-buy and blanket-order arrangements.
