1.1. Introdución
The Youmile Stepping Motor Drive Board (Model: JK-YM-349) is a versatile pulse generation module designed to control stepping motor drivers. It simplifies the process of setting up and operating stepping motors by providing the necessary control signals. This module, when combined with a stepping driver, a stepping motor, and a DC power supply, forms a complete and easy-to-use control platform.
1.2. Características clave
- Pulse Generation: Generates pulse signals for stepping motor control.
- PWM Signal Output: Capable of generating PWM signals, selectable via jumpers.
- Adjustable Frequency: Offers three frequency ranges: High (5.4kHz ~ 160kHz), Medium (540Hz ~ 16.6kHz), and Low (80Hz ~ 2.4kHz).
- Simple Control Platform: Designed for easy integration with stepping drivers and motors.
- Tamaño compacto: Approximately 38.6 x 58 mm (1.5 x 2.3 inches).

2. Configuración e conexións
2.1. Identificación de compoñentes
Familiarize yourself with the various components and connection points on the control board. The image below illustrates the key functional areas of the board, including the frequency adjustment knob, motor reverse switch, motor start/stop switch, power input, signal selection jumpers, and speed range selection jumpers.

Descrición da imaxe: Vista de arriba abaixo view of the Youmile Stepping Motor Drive Board with labels pointing to its various components. These include the frequency adjustment knob, motor reverse switch, motor start or stop switch, power input terminals (8-24V), signal selection jumpers (1-2 pulse signal, 3-4 PWM signal), speed range selection jumpers (1-2: 5.4K-160KHz, 3-4: 540-16.6KHz, 5-6: 80-2.4KHz), and common mode connection points (Common Anode and Common Cathode).
2.2. Diagrama de cableado
The control board can be connected to a stepping motor driver using either a common anode or common cathode configuration. Ensure your driver supports the chosen connection method.
Common Anode Connection Method:
Connect EN+, PUL+, DIR+ to COM+.
Connect EN- to EN.
Connect PUL- to CLK.
Connect DIR- to DIR.
Common Cathode Connection Method:
Connect EN-, PUL-, DIR- together to COM-.
Connect EN+ to EN.
Connect PUL+ to CLK.
Connect DIR+ to DIR.

Image Description: A detailed wiring diagram showing the Youmile Stepping Motor Drive Board connected to a digital stepping driver (DM 836) and a stepper motor. The diagram illustrates the power supply connection (24V DC PSU) to the driver, and the signal connections (PUL+, PUL-, ENA+, ENA-, DIR+, DIR-) from the driver to the control board's EN, DIR, CLK terminals. The stepper motor is shown connected to the driver's A+, A-, B+, B- terminals.
2.3. Fonte de alimentación
The board requires a DC power input of 8-24V. Ensure correct polarity when connecting the power supply to the designated terminals on the board. Incorrect polarity can damage the module.
3. Funcionamento
3.1. Axuste de frecuencia
The rotational speed of the stepping motor is controlled by the frequency of the pulse signal. Use the large knob on the board to adjust the output frequency. Turning the knob clockwise increases the frequency, and counter-clockwise decreases it.
3.2. Signal Selection
The board can output either a pulse signal or a PWM signal. Use the jumpers labeled 'Signal selection' (J3 on the board, referring to the function diagram) to select the desired output type:
- 1-2 Jumper: Selects pulse signal output.
- 3-4 Jumper: Selects PWM signal output.
3.3. Motor Control
The board features two switches for basic motor control:
- Motor Start or Stop Switch: This switch controls whether the motor is running or stopped.
- Motor Reverse Switch: This switch changes the direction of the motor's rotation.
4. Mantemento
To ensure the longevity and optimal performance of your Youmile Stepping Motor Drive Board, follow these maintenance guidelines:
- Manter limpo: Regularly clean the board with a soft, dry brush or compressed air to remove dust and debris.
- Evitar a humidade: Protect the board from moisture and humidity, which can cause short circuits and corrosion.
- Control de temperatura: Operate the board within its specified temperature range. Avoid extreme heat or cold.
- Manipular con coidado: Avoid dropping or subjecting the board to physical shocks.
- Power Off Before Connecting: Always disconnect power before making or changing any connections to prevent damage to the board or other components.
