5. Setup and Connections

This section details the physical connections required to operate your IBT 4 Motor Driver Controller.

Figure 5.1: Overall view of the IBT 4 Motor Driver Controller, showing the heatsink, input pins, and motor power terminals.

Figure 5.2: Detailed view of the control input pins (IN1, IN2, GND) and the motor power terminals (MOTOR-PWR +/-).

5.1. Power Connections

• Connect your DC motor's power supply to the large green screw terminals labeled MOTOR-PWR + and MOTOR-PWR -. Ensure correct polarity. The rated voltage for the motor power supply is 5V to 12V DC, with a maximum limit of 14.6V.
• The driver board itself draws power from these terminals.

5.2. Control Signal Connections

• Connect your control signals (e.g., from a microcontroller) to the yellow header pins labeled IN1, IN2, and GND.
• IN1 and IN2 are used for directional control and PWM input.
• GND is the common ground connection for the control signals.
• The input level voltage for control signals can be 0V-0.5V for low and 2.5V-13V for high, compatible with 3.3V, 5V, and 12V logic levels.

6. Operating Instructions

The IBT 4 Motor Driver Controller allows for precise control over DC motors using PWM signals.

6.1. Directional Control (CW/CCW)

Motor direction is controlled by the logic states of the IN1 and IN2 pins. Typically:

• To drive the motor in one direction (e.g., Clockwise): Set IN1 HIGH, IN2 LOW.
• To drive the motor in the opposite direction (e.g., Counter-Clockwise): Set IN1 LOW, IN2 HIGH.
• To stop the motor: Set both IN1 and IN2 LOW, or both HIGH (depending on specific motor and driver configuration, typically both LOW for brake/coast).

6.2. Speed Control (PWM)

Motor speed is controlled by applying a PWM signal to one of the input pins (e.g., IN1) while the other pin (IN2) is held at a fixed logic level (HIGH or LOW) to determine direction. The duty cycle of the PWM signal directly correlates to the motor's speed.

• Duty Cycle: The PWM duty cycle can range from 0% (motor off) to 98% (maximum speed).
• PWM Frequency: The optimal PWM frequency depends on the type of motor being controlled. Refer to the recommended frequencies in the Technical Specifications section (Section 4).

7. Important Notes and Warnings

• The input PWM duty cycle must not exceed 98%. Exceeding this value may lead to unstable operation or permanent damage to the driver.
• The selection of PWM frequency is critical and depends on the load type. When possible, use the recommended frequency values provided in the specifications or an approximate value.
• Ensure all power and control connections are secure and correctly polarized before applying power to prevent damage to the driver or connected components.

8. Troubleshooting

If you encounter issues with your IBT 4 Motor Driver Controller, consider the following:

• Motor Not Responding: Verify all power connections to the motor and the driver board. Check control signal connections (IN1, IN2, GND) for proper wiring and logic levels. Ensure the motor power supply is within the rated voltage range.
• Motor Runs Erratically: Check the PWM signal's duty cycle and frequency. Ensure they are within the specified limits and recommended values for your motor type. Inspect for loose connections or intermittent signals.
• Driver Overheating: Ensure the motor current does not exceed the maximum working current of 50A. Verify that the heatsink is properly installed and has adequate airflow. Reduce load or operating time if continuous overheating occurs.
• Incorrect Direction: Review the logic states applied to IN1 and IN2. Swap the motor's power leads if the direction is consistently inverted and control signals are correct.

9. Maintenance

The IBT 4 Motor Driver Controller is designed for reliable operation with minimal maintenance. To ensure longevity:

• Keep the board clean and free from dust and debris. Use a soft, dry brush or compressed air for cleaning.
• Avoid exposing the board to moisture or extreme temperatures.
• Periodically check all connections for tightness, especially in high-vibration environments.
