Connection Steps:

1. Connect the stepper motor's A+, A-, B+, B- phases to the corresponding terminals on the ZK-SMC02 module.
2. Connect the DC 5-30V power supply to the V+ (positive electrode) and V- (negative pole) terminals on the module. Ensure correct polarity.
3. If using external control signals (e.g., via TTL serial port), refer to the detailed internal wiring diagram (Image 4.4) for GND, EN, DIR, and PUL connections.
4. Adjust the current regulation potentiometer (0-4A) if necessary, located on the top side of the module (Image 4.3), to match your stepper motor's current requirements.
5. Set the desired subdivision using the DIP switches or jumpers, also located on the top side (Image 4.3).

5. Operating Instructions

5.1 Basic Operation

The ZK-SMC02 features an encoder knob and several buttons for intuitive control:

• Encoder Knob: Rotate to adjust speed in operation mode. Press and hold to enter the menu settings.
• CW Button: Initiates forward rotation.
• CCW Button: Initiates reverse rotation.
• RUN/STOP Button: Starts or stops the motor operation. Press and hold to exit the current operation.

5.2 Menu Settings and Parameter Adjustment

To access and adjust parameters, follow these steps:

1. Enter Menu: In the operation interface, press and hold the encoder knob to enter the menu setting interface.
2. Navigate Parameters: Rotate the encoder to adjust and change the parameter codes (e.g., F-01 to F-13).
3. Adjust Parameter Value: Briefly press the encoder to enter the corresponding menu parameter setting state. The parameter value will flash. Then, rotate the encoder to adjust the value.
4. Save and Exit: After adjusting a parameter, briefly press the RUN/STOP key to exit the parameter setting and return to the main menu number adjustment interface. To save all parameters and exit the menu, press and hold the encoder.

The module supports 9 work states and various parameters for fine-tuning motor behavior, including:

• Forward/Reverse Pulses
• Speed (RPM)
• Delay Times (Forward/Reverse)
• Cycle Times
• Subdivision Settings

6. Important Notes and Safety

Please observe the following important notes and safety guidelines:

• This module is intended for general industrial control applications.
• DO NOT USE this product in critical applications such as medical equipment, life-saving systems, fire protection systems, or any other life-critical fields.
• DO NOT USE in dangerous environments such as coal mines or oil depots where explosive atmospheres may be present.
• Electronic module products require a basic understanding of electronics for safe and effective use. Read this product description and manual carefully before operation.
• Ensure the power supply voltage is within the specified range (DC 5-30V) and observe correct polarity during connection.
• Avoid operating the module in environments outside the specified temperature range (-5°C to 60°C) or in condensing conditions.

7. Troubleshooting

If you encounter issues with your ZK-SMC02 module, consider the following:

• Motor Not Responding:
  • Check power supply connections and ensure voltage is within 5-30V DC.
  • Verify motor wiring (A+, A-, B+, B-) is correct and secure.
  • Ensure the motor is compatible (e.g., NEMA 17/23 stepper motor).
  • Check the current regulation potentiometer setting; it might be too low for the motor.
• Incorrect Motor Movement/Speed:
  • Review the set parameters (speed, pulses, delay, cycle times) in the menu.
  • Verify the subdivision setting matches your motor and desired precision.
  • Ensure the encoder knob is functioning correctly for speed adjustment.
• Display Issues:
  • Confirm stable power supply.
  • If the display is blank, check all power connections.
• Module Overheating:
  • Ensure the current regulation potentiometer is set appropriately for your motor and not excessively high.
  • Provide adequate ventilation around the module.

If problems persist after checking these points, please contact customer support for further assistance.
