3. Setup and Installation
3.1 Wiring Diagram
Proper wiring is essential for the correct operation of the ZK-SMC04. Refer to the diagrams below for power, motor, and control signal connections.
Figure 3.1: Basic product wiring diagram. Connect the DC power supply to the "Power supply +" and "Power supply -" terminals. Connect the stepper motor phases to A+, A-, B+, B- terminals.
Figure 3.2: Expansion interface and serial port output. The 8-pin expansion interface provides connections for external triggers (start/stop, switch direction), limit switches, and output signals. The serial port allows for TTL communication.
Figure 3.3: Example connection for signal, limit switches, and output. This diagram illustrates how to connect NPN normally open proximity switches for limit detection and push buttons for start/stop and direction change functions.
3.2 Driver Settings (DIP Switches)
The ZK-SMC04 features DIP switches on the board for configuring output current and microstep resolution. Ensure the power is off before adjusting these switches.
Figure 3.4: Driver settings via DIP switches. This image details how to set the output peak current, microstep resolution, chopping mode (Smooth mode SpreadCycle or Silent Mode StealthChop), and holding current (1/2 Run or iRun).
Current Setting:

4.1 Basic Operation
- Start/Stop: Press the RUN/STOP button to start or stop the motor.
- Direction Control:
- Press CW button for forward rotation.
- Press CCW button for reverse rotation.
- Speed/Angle Adjustment: Rotate the encoder setting knob to adjust parameters such as speed or angle.
4.2 Menu Navigation and Parameter Settings
The ZK-SMC04 allows for detailed configuration through its menu system. Follow these steps to navigate and adjust parameters:
Figure 4.2: Menu navigation and parameter adjustment. This diagram shows how to stop running and exit, enter menu settings, tune parameters, and exit parameter settings using the rotary encoder and buttons.
- Stop Running and Exit: On the running interface, adjust the speed using the rotary encoder. Press the CW button for forward rotation, CCW button for reverse. Long press the RUN/STOP button to stop running and exit.
- Enter Menu Settings: From the running interface, long press the encoder to enter the menu settings interface.

| Incorrect position | Signal interference | Remove interference. |
| The motor wire has a broken circuit | Check and connect correctly. | |
| Subdivision error | Set up correct segmentation. | |
| Motor stalling vibration | The current is too small | Increase the current. |
