Features:
- A built-in oscillator generates motion commands for two-phase stepping motors.
- Analog voltage at the SPEED terminal varies the commanded stepping rate.
- Current-down and fault-detection circuits support controlled driver operation.
RD-323MS uses a unipolar constant-current chopper stage to regulate winding current throughout each microstep.
Its selectable division table provides up to eighty command pulses for one basic motor step.
Low-speed, high-speed, and acceleration controls shape the motion profile directly at the driver.
The RORZE RD-323MS 2-Phase Microstepping Motor Driver may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Winding and Current Requirements
- Motor construction: Compatible loads are two-phase HB or PM stepping motors.
- Lead arrangement: The unipolar output is intended for four- or six-lead winding connections.
- Phase setting: Driver current is adjustable from 0.3 to 3 A for each motor phase.
- Voltage boundary: Motor rated voltage must remain within the documented relationship to the DC supply.
Oscillator and Ramp Control
- Clock source: The internal oscillator reaches a maximum stepping frequency of 700 kpps.
- Division range: Selectable clock output spans one to eighty pulses for each basic step.
- Speed input: Voltage at the SPEED terminal continuously adjusts the oscillation rate.
- Ramp timing: Acceleration and deceleration are adjustable from 20 milliseconds to 3 seconds.
Driver Safeguards
- Thermal detection: An internal circuit reacts when the driver exceeds its allowable temperature.
- Current monitoring: Overcurrent protection limits damage from an abnormal output condition.
- Supply supervision: Low-voltage detection identifies an inadequate 18-to-40 VDC input.
- Stopped-motor reduction: Automatic current down lowers phase current after roughly 0.3 seconds of inactivity.
Mounting and Cooling
- Supply connection: The DC input must remain between 18 and 40 V including ripple.
- Case cooling: The enclosure should conduct heat to a suitable metal mounting surface.
- Temperature check: Operating airflow must keep the case at or below the stated 60°C limit.
- Forced ventilation: A fan is added when natural heat dissipation cannot maintain the required case temperature.
