Wiring Diagram | Zk1200-dh

If you have a specific variant (e.g., ZK1200-DH with fingerprint reader or PoE), refer to the exact silkscreen on your board, as pinouts may differ slightly by manufacturing batch. Always verify with a multimeter before applying power.

Below is a breakdown of its wiring diagram, terminal functions, and common connection pitfalls. If you have a specific variant (e

| Symptom | Most Likely Cause | Solution | | :--- | :--- | :--- | | Motor does not move, no holding torque | Power not reaching driver, or ENA signal active (disabled) | Check VCC/GND voltage. Float ENA+ and ENA- to re-enable. | | Motor vibrates but does not rotate | One phase wired incorrectly | Swap A+ and A- (or swap B+ and B-). | | Motor loses steps randomly | Electrical noise on PUL/DIR lines | Use shielded twisted-pair. Separate signal wires from power wires. Add 10k pull-up resistors on signals. | | Driver overheats | Current DIP switch set too high | Reduce run current to match motor spec (e.g., 4.2A RMS). | | Motor runs only in one direction | DIR signal not connected or controller not toggling DIR pin | Check DIR+ and DIR- wiring. Measure voltage at DIR pin when controller changes direction. | | Erratic movement at high speed | Power supply voltage too low | Increase PSU voltage (within driver limit, e.g., 80VDC). | | Symptom | Most Likely Cause | Solution

Propping the rear wheel off the ground is a critical precaution. If there is a wiring error or a faulty component, the motor may spin at full speed immediately upon connection.
