ZK-SMC02 CNC Stepper Motor Driver

1. Description

The ZK-SMC02 is an operation control module specifically designed for single-axis stepper motors. It features built-in multiple fixed operation modes, allowing users to quickly select the appropriate motion trajectory. The module can save setting parameters after power off. It supports setting distance, speed, delay, and cycle times. It can function independently as a module or be integrated with other systems, making it suitable for general industrial control applications.

2. Features

• Integrated Controller & Driver: Combines step motor controller and driver functions, enabling real-time control of the stepper motor's working state.
• Forward & Reverse Control: Rotation direction can be changed via buttons or a potentiometer. Direction can also be automatically switched based on the selected working mode for multi-scene applications.
• Multiple Control Modes: Supports built-in parameter work mode and control via external buttons or other drivers.
• 9 Work States: Includes 9 default workflow programs covering most applications, such as Forward/Reverse, Delay, Loop, Self-locking, No-lock, and Rotating speed.
• HD LCD Display: Clearly displays speed, delay, and cycle times, facilitating easy browsing and parameter setting. Enables high-precision motor control. Parameters are stored in memory and retained after power off.

• Rotate the potentiometer to adjust the forward or reverse rotation speed. Note: Operation mode may differ based on selected modes.
• Press and hold the potentiometer for more than 3 seconds to enter parameter set mode.

4.2. Parameter Interface

• After entering parameter set mode, rotate the potentiometer to select parameters F-01 to F-13.
• The selected parameter will blink.
• Press the potentiometer to select the parameter value.
• Modify Value Method 1: Directly rotate the potentiometer to change the value.
• Modify Value Method 2: Press the potentiometer again to make the selected bit blink. Rotate the potentiometer to change the value for that bit from 0 to 9. Repeat for other bits to improve setup efficiency.
• Press the RUN/STOP button to return to the parameter list (Note: parameters and parameter values are distinct).
• Set other parameters and values as needed.
• Save and exit parameter set mode by pressing and holding the potentiometer for more than 3 seconds.

4.3. Auxiliary Function

• The module can operate independently by default. Connect the power supply and stepper motor; no other accessories are required.
• Users can connect external control buttons to change the operation mode. External control buttons can be connected to the COM/STOP/CCW/CW/OUT terminals on the PCB.
• Users can also connect other types of stepper motor drivers and use the ZK-SMC02 solely as a stepper motor controller.
