The RD-323MS is a two-phase microstepping motor driver used in high-end automation fields such as semiconductor manufacturing, LCD panel processing, and precision medical analysis. Within an extremely small volume, this product integrates microstepping division technology and control logic. Its core highlight is the built-in pulse oscillator, which completely removes the reliance on high-frequency pulses from an external PLC or motion control card, requiring only basic switch and analog signals to achieve independent axis motion management.
Built-in Independent Pulse Source
Advanced Microstepping Technology
High Power Density Compact Footprint
The RD-323MS implements high-order microstepping division technology, which splits the motor's inherent basic step angle into smaller incremental microsteps. This approach counters the structural resonance, structural vibration, and acoustic noise typical of standard stepper motors operating at low angular velocities, yielding fluid motion trajectories and enhancing micrometer-level mechanical positioning resolutions. Operating on an industry-standard 24 VDC stabilized direct-current supply, the drive module outputs constant-current bipolar driving capabilities up to 3.0A per phase within a compact footprint, making it fully compatible with various small-to-medium 2-phase stepper motors. Furthermore, the housing integrates onboard DIP switches and fine-tuning potentiometers, which work alongside internal overcurrent and overtemperature safety interlocking logic and thermal dissipation backplanes to guarantee structural stability during continuous 24/7 industrial campaigns.

Deployed in the Z-axis vertical control of automated pick-and-place or dispensing machines to precisely govern dispensing height and pressure.
Medical & Analytical Instruments
Used for sample tray rotation in fully automated blood analyzers, where vibration-free rotation ensures liquid samples do not form bubbles or splash.
Food & Beverage Filling Machinery
Applied in bottle-clamping rotation or small conveyor belt speed regulation on filling lines, removing the hardware cost of high-speed pulse modules.
Printing & Paper Converting
Utilized in automated web guiding systems for label printing presses, adjusting paper edge positions quickly and incrementally through microstep motion.
Commercial Automation Devices
Applied in the banknote or merchandise transport belts within vending machines and automated teller machines (ATMs), managing startup and stoppage via simple electrical levels.
Key precautions for RORZE RD-323MS, ensure the correct polarity of the 24VDC stabilized power supply, as reverse connection will instantly burn out the power chips. Mount the drive on a conductive metal surface with adequate heat dissipation, and add forced fan cooling during continuous high-current output (near 3A) to prevent overheating. Prior to wiring, strictly verify the current and microstep settings via the onboard DIP switches based on the motor's rated current and system specifications, and always perform wiring changes with the power completely turned off.

Technical notes
Technical notes
The RORZE RD-323MS is a 2-Phase Microstepping Motor Driver for semiconductor and precision automation industries. Its core feature is the built-in pulse oscillator, which enables independent speed regulation and motion control via 0-5V analog voltage or switch signals without an external PLC. Its advanced microstepping technology eliminates low-speed motor vibration and resonance. Operating on a 24VDC supply, it supports up to 3.0A per phase, delivering a compact, smooth, and cost-effective motion control solution.
The RD-323MS is a high-precision, high-performance 2-phase microstepping motor driver produced by RORZE Corporation (Japan), featuring a built-in pulse oscillator.
How do you properly use products like the RD-323MS?
To use it, mount it on a well-ventilated metal plate, configure the drive current and microstep resolution via DIP switches, connect the 24VDC power supply and a 2-phase stepper motor, and finally control its speed and direction using external switch signals and analog voltage.
What is the function of the built-in oscillator in the RD-323MS?
The built-in oscillator eliminates the need for an upper controller (like a PLC or motion card) to send high-frequency pulses. It generates its own pulses to drive and regulate motor speed based purely on simple switch signals or analog voltage.
Which industrial sectors primarily use the RD-323MS?
It is widely used in semiconductor manufacturing equipment (such as vacuum manipulators), LCD panel production lines, precision medical analytical instruments, and automated packaging machinery where high smoothness, compact size, and cleanliness are critical.
How do you adjust the motor speed controlled by the RD-323MS?
Since it features a built-in oscillator, you can vary the motor speed by applying a 0 to 5V DC analog voltage to its external SPEED terminal, or by turning the onboard potentiometer.
