6. Operating Instructions
6.1. Parameter Settings (DIP Switches)
The HSS86 driver features DIP switches (SW1-SW8) for configuring microstep resolution and motor direction. Refer to Figure 5 for the location of these switches.
6.1.1. Microstep Resolution Setting (SW1-SW4)
Switches SW1 to SW4 are used to set the microstep resolution (pulses per revolution). Consult the driver's label or specific documentation for the exact configuration table. Incorrect settings can lead to inaccurate movement.
6.1.2. Motor Direction Selection (SW5)
Switch SW5 typically controls the motor's rotation direction (Clockwise/Counter-Clockwise). Refer to the driver's label for the specific ON/OFF configuration for desired direction.
6.1.3. Other Settings (SW6-SW8)
Switches SW6 to SW8 may control other parameters such as idle current reduction or self-test functions. Refer to the driver's specific documentation for their functions.
6.2. Initial Power-Up
After completing all wiring and settings, apply power to the driver. The Green LED (POWER) should illuminate. If the Red LED (ALARM) illuminates, refer to the Troubleshooting section.
6.3. Control and Operation
Send pulse and direction signals from your CNC controller to the driver. The motor will respond according to the input signals and configured microstep resolution. Monitor the motor's movement and ensure it operates smoothly without excessive noise or vibration.
7. Maintenance
The RATTMMOTOR servo system is designed for reliability with minimal maintenance. However, adhering to the following guidelines will help ensure long-term performance:
- Environmental Control: Keep the operating environment clean and free from dust, metal shavings, oil mist, and corrosive gases.
- Temperature: Ensure the ambient temperature remains within the specified operating range (0~50℃) and that the driver has adequate cooling. Periodically check for any obstructions to airflow around the driver's heatsink.
- Connections: Periodically inspect all electrical connections for tightness and signs of wear or corrosion. Loose connections can lead to intermittent operation or damage.
- Cleaning: Gently clean the exterior of the motor and driver with a soft, dry cloth. Do not use solvents or abrasive cleaners.

If you encounter issues with your RATTMMOTOR servo system, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor does not move | No power to driver; Incorrect wiring; Enable signal not active; No pulse signal; Motor or driver fault. | Check power supply and connections; Verify motor and encoder wiring; Ensure ENA+ and ENA- are correctly connected and active; Check pulse signal from controller; Contact support if fault persists. |
| Motor moves erratically or loses steps | Incorrect microstep setting; Noise on control signals; Encoder wiring issue; Overload. | Verify DIP switch settings for microstep resolution; Use shielded cables for control signals; Check encoder cable for damage or loose connections; Reduce load or adjust motor current. |
| Driver Red ALARM LED is on | Over-voltage/Under-voltage; Over-current; Encoder error; Position deviation error. | Check power supply voltage; Inspect motor and encoder wiring for shorts or open circuits; Reduce load; Check for mechanical binding; Cycle power to reset. |
| Motor overheats | Excessive load; Insufficient cooling; Incorrect current setting. | Reduce mechanical load; Ensure adequate ventilation around motor and driver; Verify current settings are appropriate for the application. |
