4. Safety Information
Always observe the following safety precautions to prevent injury or damage to the product:
- Ensure the power supply voltage matches the controller's specifications (220V AC).
- Disconnect power before making any wiring connections or performing maintenance.
- All wiring should be performed by a qualified electrician or knowledgeable individual.
- Ensure proper grounding to prevent electrical shock.
- Do not operate the controller in wet or damp conditions.
- Avoid exceeding the maximum rated power (400W) of the controller.
- Keep the device away from flammable materials and excessive heat sources.
- Do not attempt to modify or disassemble the controller. Refer all servicing to qualified personnel.
5. Setup and Installation
Follow these steps for proper installation of the speed controller. Refer to the wiring diagrams and terminal block labels for accurate connections.
5.1 Wiring Diagram Overview
Figure 2: Internal wiring diagram showing connections for speed control and motor.
Figure 2 illustrates the internal connections of the speed control unit to the speed control motor. Note the color-coded wires: Yellow, Blue, White, Green, and Red, corresponding to specific functions within the motor and controller.
5.2 Terminal Block Connections
Figure 3: Terminal block with numbered connections and functions.
Refer to Figure 3 for the terminal block connections. Ensure all connections are secure and correctly matched to prevent malfunction or damage.
- Terminal 1 (Yellow): Ground wire (FG). Connect to earth ground.
- Terminal 2 (AC-L): AC input Live wire (220V-240V 50/60Hz).
- Terminal 3 (AC-N): AC input Neutral wire (220V-240V 50/60Hz).
- Terminal 4 (Red): Mainline. Connects to the main power input of the motor.
- Terminal 5 (CW): Clockwise rotation control.
- Terminal 6 (CCW): Counter-clockwise rotation control.
- Terminal 7 (COM): Common terminal for direction change.
- Terminal 8 (S1): Tachometer input S1 (Blue).
- Terminal 9 (S2): Tachometer input S2 (Blue).
For direction change, connect a switch between Terminal 7 (COM) and either Terminal 5 (CW) or Terminal 6 (CCW). For example, connecting COM to CW will set the motor to clockwise rotation.

Figure 4 provides a visual reference for how the wires should be connected to the terminal block. Ensure all wires are properly stripped and inserted into their respective terminals, then tightened securely.
6. Operating Instructions
Once the controller is correctly installed and wired, follow these steps to operate your AC gear motor:
- Power On: Connect the main power supply to the controller. The LED display should illuminate, showing the current motor speed (R/MIN).
- Speed Adjustment: Rotate the large knob on the front panel to adjust the motor speed. Turning the knob clockwise will increase the speed, and counter-clockwise will decrease it. The LED display will show the adjusted speed in real-time.
- Direction Control: Use the forward/backward switch (if installed, connected to terminals 5, 6, and 7) to change the motor's rotation direction. Ensure the motor has come to a complete stop before changing direction to prevent damage.
- Stop Function: Press the red "STOP" button located below the speed control knob to immediately stop the motor.
- Power Off: Disconnect the main power supply when the controller is not in use for extended periods.
The controller provides stepless speed adjustment, allowing for fine-tuning of motor performance. Monitor the LED display for accurate speed readings.
7. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your speed controller:
- Cleaning: Periodically clean the exterior of the controller with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no dust or debris accumulates in ventilation openings.
- Inspection: Regularly inspect all wiring connections to ensure they are secure and free from corrosion or damage. Check for any signs of overheating or unusual odors.
- Environment: Ensure the controller is operated in a clean, dry environment, free from excessive dust, moisture, and extreme temperatures.
- Ventilation: Do not obstruct the ventilation openings of the controller to allow for proper heat dissipation.
8. Troubleshooting
If you encounter issues with your speed controller, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller does not power on / LED display is off. | No power supply; incorrect wiring; blown fuse. | Check power connection and source. Verify AC input wiring (Terminals 2 & 3). Inspect for internal fuse (if accessible and replaceable). |
| Motor does not run. | Motor not connected; incorrect motor wiring; motor fault; speed knob set to minimum. | Ensure motor is correctly wired to Terminal 4 (Mainline) and other motor control wires. Increase speed using the knob. Test motor independently if possible. |
| Motor speed is unstable or fluctuates. | Loose connections; motor overload; faulty motor or controller. | Check all wiring connections for tightness. Reduce motor load. If problem persists, consult support. |
| Motor does not change direction. | Incorrect direction control wiring; faulty switch. | Verify connections to Terminals 5 (CW), 6 (CCW), and 7 (COM). Ensure the direction switch is functioning correctly. |
| Overheating of controller or motor. | Motor overload; insufficient ventilation; short circuit. | Reduce motor load. Ensure adequate airflow around the controller. Immediately disconnect power and inspect for short circuits if overheating is severe. |
