Wiring Guide
Interface Definition
| Terminal Name | Function Description |
|---|---|
| DC+ | Positive pole of DC power supply (18-50V) |
| DC- | Negative pole of DC power supply (ground) |
| A+/A- | Motor phase A coil connections (polarity-sensitive, avoid miswiring) |
| B+/B- | Motor phase B coil connections (polarity-sensitive, avoid miswiring) |
| PUL+ | Positive terminal of pulse control signal (optically isolated) |
| PUL- | Negative terminal of pulse control signal (optically isolated) |
| DIR+ | Positive terminal of direction control signal (optically isolated) |
| DIR- | Negative terminal of direction control signal (optically isolated) |
| ENA+ | Positive terminal of enable signal (high level enabled; floating = enabled) |
| ENA- | Negative terminal of enable signal (low level disabled) |
| ALM | Alarm output (active when fault occurs: overvoltage/overcurrent/overheating) |
Wiring Methods
Power Wiring
- Use non-regulated DC power supply (recommended) or regulated switching power supply (set to max output current)
- Ensure correct polarity of DC+ and DC-; reverse connection will damage the driver
- For multiple drivers, connect power in parallel at the power supply end (avoid daisy-chain connection)
Motor Wiring
- Connect motor A-phase coil to A+/A-, B-phase coil to B+/B- (match motor wiring diagram)
- Do not connect motor wires to power terminals; avoid short-circuit between motor phases
- Do not hot-plug motor connectors when powered on (high induced voltage may damage the driver)
Control Signal Wiring
- Common Anode Connection: Connect PUL+/DIR+/ENA+ to controller's signal output; PUL-/DIR-/ENA- to controller's GND
- Common Cathode Connection: Connect PUL-/DIR-/ENA- to controller's signal output; PUL+/DIR+/ENA+ to controller's VCC (4.5-28V)
- Use shielded cables for control signals (single-end grounding at controller side, 10cm+ distance from motor wires to avoid interference)
Wiring Notes
- All wire ends must not be exposed outside terminals (prevent short-circuit)
- Do not solder wire ends before inserting into terminals (avoid overheating and poor contact)
- Tighten terminal screws firmly to prevent loose connections and abnormal heating
DIP Switch Settings
Switch Position Definition
| Switch Group | Function |
|---|---|
| SW1-SW3 | Dynamic current adjustment (peak current) |
| SW4 | Idle current mode / Auto-tuning function |
| SW5-SW8 | Microstep resolution adjustment |
Current Setting (SW1-SW3)
| Peak Current | RMS Current | SW1 | SW2 | SW3 |
|---|---|---|---|---|
| 1.0A | 0.71A | ON | ON | ON |
| 1.46A | 1.04A | OFF | ON | ON |
| 1.92A | 1.36A | ON | OFF | ON |
| 2.37A | 1.69A | OFF | OFF | ON |
| 2.84A | 2.03A | ON | ON | OFF |
| 3.32A | 2.36A | OFF | ON | OFF |
| 3.76A | 2.69A | ON | OFF | OFF |
| 4.20A | 3.00A | OFF | OFF | OFF |
Idle Current & Auto-Tuning (SW4)
| Function | SW4 State | Operation Description |
|---|---|---|
| Idle Current (50%) | OFF | Auto-reduce to 50% of dynamic current after 400ms of pulse stop (reduces heating) |
| Idle Current (100%) | ON | Idle current = dynamic current (for high holding torque requirements) |
| Auto-Tuning Function | Toggle | Flip SW4 ON↔OFF within 1 second (no pulse input during operation; optimizes motor parameters) |
Microstep Setting (SW5-SW8)
| Steps/Rev | SW5 | SW6 | SW7 | SW8 |
|---|---|---|---|---|
| 400 | OFF | ON | ON | ON |
| 800 | ON | OFF | ON | ON |
| 1600 | OFF | OFF | ON | ON |
| 3200 | ON | ON | OFF | ON |
| 6400 | OFF | ON | OFF | ON |
| 12800 | ON | OFF | OFF | ON |
| 25600 | OFF | OFF | OFF | ON |
| 1000 | ON | ON | ON | OFF |
| 2000 | OFF | ON | ON | OFF |
| 4000 | ON | OFF | ON | OFF |
| 5000 | OFF | OFF | ON | OFF |
| 8000 | ON | ON | OFF | OFF |
| 10000 | OFF | ON | OFF | OFF |
| 20000 | ON | OFF | OFF | OFF |
| 25000 | OFF | OFF | OFF | OFF |
Setting Notes
- Power off the driver before adjusting DIP switches (settings take effect after power-on)
- Match the set current to the motor's rated current (do not exceed motor maximum current)
- For low-noise and high-precision requirements, select 400 steps/rev or higher microstep resolution
