STEPPERONLINE ST-C01 Single Axis Stepping Motor Controller
1. Product Introduction
The ST-C01 is a special operation control module designed for single-shaft stepping motors. It features a variety of built-in fixed operation modes, allowing users to quickly select the appropriate motion trajectory. Key parameters such as distance, speed, delay, and number of cycles can be saved and retained even after power loss. The module can operate independently or integrate with other systems. It is suitable for general industrial control applications but is not recommended for medical, fire, or other specialized industries, or for life-critical areas.

The manual also includes tables for driver current settings (SW1-SW8) and pulse/revolution settings for various drivers.
6. Interface Function Introduction and Operation Method
The controller has two main interfaces: the RUN INTERFACE and the MENU SETTING INTERFACE.
- RUN INTERFACE: Displays running information such as speed (RPM), delay time, and number of cycles. Users can adjust speed using the encoder knob. The CW and CCW buttons control forward and reverse rotation, respectively. The RUN/STOP button can be used to stop the operation or exit the current interface. A long press of the encoder knob enters the menu settings.
- MENU SETTING INTERFACE: Allows modification of parameters. The encoder knob is used to change parameter codes (F-01 to F-13). A long press of the knob saves the parameter and exits to the running interface. Short pressing the knob navigates through parameter settings (F-XX), and short pressing the RUN/STOP button exits the parameter setting and returns to the main menu.
Operating Instructions Summary:
- Run stop exit: Turn knob to adjust speed. CW for forward, CCW for reverse. RUN/STOP stops and exits. Long press encoder to enter menu settings.
- Menu Navigation: In the menu setting interface, turn the knob to change parameter codes (F-01 to F-13). Long press the knob to save and exit.
- Parameter Tuning: In the menu setting interface, short press the knob to enter F-XX parameter settings. Short press again to shift parameters. Rotate the knob to adjust the parameter value. Short press RUN/STOP to exit parameter setting and return to the main menu.

SMC01 Stepper Motor Controller Communication Protocol
This section details the communication protocol for the SMC01 controller, which uses TTL serial transmission and the MODBUS-RTU protocol. It supports function codes 0x03, 0x06, and 0x10.
2.1 Introduction to Communication Protocol
Information transmission is asynchronous in Modbus-RTU mode with the following characteristics:
- Starting bit: 1 bit
- Data bits: 8 bit
- Parity bit: not have
- Stop bit: 1 bit
Data Frame Structure:
| Data frame interval | Address code | Function code | Data area | CRC check |
|---|---|---|---|---|
| 3.5 bytes or more | 1 byte | 1 byte | N byte | 2 byte |
Data transmission requires a bus rest time of at least 3.5 bytes (e.g., 5ms at 9600 baud rate). The entire message frame is treated as a continuous data stream.
1.1 Address Code
The address code is the first byte (8 bits) of each communication frame, ranging from 1 to 255. It identifies the slave device that should receive the information. Each slave must have a unique address code.
1.2 Function Code
The function code is the second byte and defines the action the slave should take. It ranges from 1 to 127. The slave returns the same function code to indicate a response.
Supported Function Codes:
| Function code | Definition | Operation (binary) |
|---|---|---|
| 0x03 | Read register data | Read data from one or more registers |
| 0x06 | Preset Single Register | Write a set of binary data into a single register |
| 0x10 | Write multiple registers | Write multiple sets of binary data into multiple registers |
1.3 Register
Protocol registers store system parameters and run information. Each register address can hold double-byte data.
System parameters, written will be stored:
| Name | Illustrate | Byte count | Reading and writing | Register address |
|---|---|---|---|---|
| F-01 | Action process mode selection | 2 | R/W | 0000H |
| F-02 | Number of forward pulses | 4 | R/W | 0001H |
| F-03 | Forward rotation speed | 2 | R/W | 0003H |
| F-04 | Reverse pulse count | 4 | R/W | 0004H |
| F-05 | Reverse speed | 2 | R/W | 0006H |
| F-06 | Number of working cycles | 2 | R/W | 0007H |
| F-07 | Forward to position delay | 2 | R/W | 0008H |
| F-08 | Reverse in place delay | 2 | R/W | 0009H |
| F-09 | Number of pulses per revolution | 2 | R/W | 000AH |
| F-10 | Main interface display content | 2 | R/W | 000BH |
| F-11 | Action when pressing the pause key | 2 | R/W | 000CH |
| F-12 | Acceleration and deceleration levels | 2 | R/W | 000DH |
| F-13 | Module address 1-255 | 2 | R/W | 000EH |
| COM | Control command 0 using serial port instead of 1 using serial port control | 2 | R/W | 000EH |
Read information and run information:
| Description | Byte count | Reading | Register address |
|---|---|---|---|
| Current motor operating status: 00- stop 01- acceleration status 02- deceleration status 03- constant | 2 | R | 0010H |
| Current motor rotation direction: 00- forward rotation 01- reverse | 2 | R | 0011H |
Serial Port Control Run Command: (Set COM (000F) address to 1 serial port control mode before serial port control)
| Serial Port Control Command | Byte count | Reading/Writing | Register |
|---|---|---|---|
| Serial port control operation mode: 00- forward rotation 01- reverse rotation 02- slow stop 03- immediate stop 0xFF - default state | 2 | R/W | 0100H |
| Serial port control for running, 00- no permanent rotation 01- enable permanent rotation default 0 | 2 | R/W | 0101H |
| The distance of the serial port control operation is 16 bits higher than the pulse count (which works under permanent rotation), with a default of 10000 bits | 2 | R/W | 0102H |
| The distance of the serial port control operation is 16 bits lower than the pulse count (which works under permanent rotation), with a default of 10000 bits | 2 | R/W | 0103H |
