5. Operating Instructions
The speed controller allows for precise adjustment of the motor's rotational speed.
5.1 Speed Adjustment
- The speed controller features a knob for adjusting motor speed.
- One mode of adjustment is scaled from 10% to 90%, where each mark represents a 10% increment of the maximum speed.
- An alternative infinite adjustment mode is available with 'HIGH', 'RUN', and 'LOW' settings for fine-tuning.
- The indicator light on the speed controller shows whether the unit is energized.

5.2 Reversible Function
The motor supports reversible operation, allowing for changes in rotational direction as needed for various applications.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your motor.
- The gearbox is pre-greased from the factory. However, it is recommended to refill the gearbox with appropriate lubricant after approximately 100 hours of use.
- Periodically inspect all connections and fasteners to ensure they remain secure.
- Keep the motor and controller free from dust and debris.
7. Troubleshooting
Refer to the following guidelines if you encounter issues during operation.
- Motor Not Operating: Ensure all wires are correctly connected and power is supplied to the speed controller.
- Motor Overheating or Reduced Performance:
- If the motor is lightly loaded and not running for extended periods, the controller can be adjusted to 50% of full speed.
- When the motor is under load and operating continuously for a long duration, the controller speed should not be set below 70% of full speed. Reducing the speed too much under load can decrease torque, potentially leading to overload. This increases current, worsens heat dissipation, and can cause severe motor heating, shortening its service life.
- Incorrect Output Shaft Speed: The output shaft speed is determined by the motor speed divided by the reduction ratio. Verify the correct reduction ratio for your application.
