ZK-SMC02 Stepper Motor Driver Controller User Manual

1. Introduction

The ZK-SMC02 Stepper Motor Driver Controller is an integrated board designed for precise control of single-axis stepper motors. This module features a variety of built-in fixed operating modes, allowing users to quickly select the appropriate motion trajectory for their application. It supports saving and setting parameters such as distance, speed, delay, and number of cycles, even after power-off. The ZK-SMC02 can operate independently or be integrated with other systems, making it suitable for general industrial control applications.

2. Setup

Before operating the ZK-SMC02, ensure proper connections for power and the stepper motor.

2.1 Power Supply Connection

Connect a DC power source within the range of 5V to 30V to the power input terminals. Observe polarity: connect the positive terminal of the power supply to the 'VIN' or '+' terminal and the negative terminal to the 'GND' or '-' terminal on the controller board.

2.2 Stepper Motor Connection

The ZK-SMC02 supports common cathode stepper motors. Connect the motor's phase windings to the corresponding terminals (A+, A-, B+, B-) on the controller. Refer to your stepper motor's datasheet for correct winding identification.

2.3 External Control Connections (Optional)

The module can be controlled via external buttons or UART serial communication. Consult the detailed wiring diagram for specific pinouts if utilizing these advanced control methods.

3. Operating Instructions

The ZK-SMC02 offers intuitive control through its LCD display and physical buttons/rotary encoder.

3.1 LCD Display Overview

The LCD screen clearly displays operational parameters such as speed, delay times, and cycle counts. This allows for high-precision motor control and real-time monitoring of the current settings.

3.2 Control Buttons and Rotary Encoder

• CW / CCW Buttons: These buttons are typically used to initiate clockwise (CW) or counter-clockwise (CCW) rotation, or to navigate menu options.
• RUN/STOP Button: Toggles the motor's operation between running and stopped states.
• Rotary Encoder: Used for adjusting numerical parameters such as speed, distance, delay, and cycle times. Pressing the encoder often confirms a selection or enters a setting mode.

3.3 Operating Modes and Parameter Setting

The module has multiple fixed operating modes. Users can select the desired mode to achieve specific motion profiles. Parameters like speed (0.1-999 circles/minute), forward/reverse pulses (1-9999), cycle times (1-9999), and delay times (0.0-999.9 seconds) can be set and stored. The controller parameters support a memory function, meaning settings are retained even after power is removed.

3.4 System Functions

The system supports various control methods:

• Automatic Mode: Executes pre-programmed motion sequences.
• Manual Mode: Allows direct control of motor movement.
• Setting Mode: For configuring operational parameters.
• Serial Port Control: Enables remote control via TTL serial interface.

4. Maintenance

To ensure the longevity and optimal performance of your ZK-SMC02 controller, follow these general maintenance guidelines:

• Operating Environment: Operate the module within the specified temperature range of -5°C to 60°C. Avoid environments with high humidity or condensation.
• Cleanliness: Keep the module clean and free from dust, dirt, and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners or solvents.
• Connections: Periodically check all electrical connections to ensure they are secure and free from corrosion.
• Storage: When not in use for extended periods, store the module in a dry, cool place away from direct sunlight and extreme temperatures.

5. Troubleshooting

If you encounter issues with your ZK-SMC02 controller, consider the following common troubleshooting steps:

• No Power/Display:
  • Verify that the power supply is connected correctly and provides the specified voltage (DC 5-30V).
  • Check for loose connections or damaged wires.
• Motor Not Moving:
  • Ensure the stepper motor is correctly wired to the A+, A-, B+, B- terminals.
  • Check if the motor is compatible with the common cathode signal type.
  • Verify that the 'RUN/STOP' button is in the 'RUN' state.
  • Review the set parameters (speed, pulses, delay) on the LCD to ensure they are appropriate for your motor and application.
• Erratic Motor Movement:
  • Check for electrical noise or interference in the environment.
  • Ensure the power supply is stable and provides sufficient current (up to 4A drive power).
  • Verify the subdivision selection is appropriate for your motor and desired smoothness.
• Parameters Not Saving:
  • Ensure that parameters are correctly confirmed after adjustment (e.g., by pressing the rotary encoder). The module has a memory function, so settings should persist.

If problems persist after following these steps, please refer to the support section for further assistance.
