| 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) |
| Switch Group | Function |
|---|---|
| SW1-SW3 | Dynamic current adjustment (peak current) |
| SW4 | Idle current mode / Auto-tuning function |
| SW5-SW8 | Microstep resolution adjustment |

| 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) |
