P430 / DM430 Stepper Driver - Core Specifications
I. Key Features
- 32-bit ARM digital control for low vibration, low noise, low heat generation and smooth operation
- Adjustable peak current from 0.14–3.0A, automatic idle half-current function for significant power consumption reduction
- Microstepping range of 200–51200ppr (1–256 microsteps) with built-in microstepping algorithm for high microstepping performance at low command frequency
- Optocoupler isolated differential/single-ended signal input with strong anti-interference capability, maximum pulse frequency of 160KHz
- Automatic motor parameter calibration on power-on for high adaptability; overvoltage/undervoltage/overcurrent protection for high reliability
- Control modes: Pulse+Direction / Dual Pulse, supporting common cathode/common anode/differential wiring
II. Motor Compatibility
- Applicable to: NEMA 8/11/14/16/17 (20/28/35/42mm) two-phase hybrid stepper motors (4/6/8 wires all compatible)
- Matching principle: Motor rated current ≤3.0A, operating voltage 12–32VDC (24VDC recommended)
- Typical models: 42mm stepper motors (e.g., 17HS series), 35/28/20mm small stepper motors

IV. Standard Wiring Diagram (Text Version)
1. Motor Wiring (Universal for 4/6/8 Wires, 4-wire as standard)
- Driver terminals: A+, A-, B+, B-
- 4-wire motor: A+ (Red), A- (Green), B+ (Yellow), B- (Blue) (match with motor label)
- 6/8-wire motor: Series/parallel the same-phase windings (short-circuit same-phase terminals) first, then connect to A+/A-, B+/B-
2. Control Signal Wiring (Pulse+Direction, Common Cathode - Most Commonly Used)
- PUL+ → PLC/Controller Pulse Output + (5–24V)
- PUL- → Common GND
- DIR+ → Direction Signal +
- DIR- → Common GND
- ENA+ (Optional) → Enable Signal + (enabled by default when floating)
- ENA- → Common GND
- Differential mode: Connect PUL+/PUL-, DIR+/DIR- to positive/negative terminals of differential signal
3. Power Supply Wiring
- VCC → DC Power Supply Positive (12–32VDC)
- GND → DC Power Supply Negative (common ground with control signal GND)
V. Current/Microstepping DIP Switch Settings (Universal Version)
- Current DIP switches (8/16-bit): Adjust in 0.1A steps up to 3.0A according to driver label
- Microstepping DIP switches: Commonly used 16/32/64/128/256 microsteps, corresponding to 200/400/800/1600/3200/51200ppr
- Note: Set current to 80–100% of the motor's rated current; higher microstepping means higher positioning accuracy and lower maximum speed
