- Speed Adjustment: Use the + and - buttons to increase or decrease the sewing speed. The current speed setting will be displayed on the digital screen.
- Start/Stop: The foot pedal typically controls the start and stop of the motor.
- Needle Position: The T button (Needle Up/Down) allows you to precisely position the needle.
- Thread Trim: The C button (Cut) activates the automatic thread trimming function, if supported by your sewing machine.
- Sewing Light: The L button controls the sewing light.
3. Parameter Settings
The control box allows for advanced parameter adjustments to fine-tune performance. Refer to the specific programming guide for your sewing machine model for detailed parameter descriptions.
- Program/Parameter (P): Enter parameter setting mode.
- Mode/Menu (M): Navigate through different menus or modes.
- Enter/Set (E): Confirm selections or save parameter changes.
- Reset/Return (R): Exit a menu or reset a setting.
- Function/Forward/Reverse (F): May control motor direction or other special functions.
The digital displays show current speed, error codes, or parameter values depending on the mode.
Maintenance
Regular maintenance ensures optimal performance and longevity of your control box.
- Cleaning: Keep the control box clean and free from dust, lint, and oil. Use a soft, dry cloth. Do not use liquid cleaners directly on the unit.
- Ventilation: Ensure the heat sink fins on the bottom of the unit (Figure 6) are not obstructed to allow for proper heat dissipation.
- Cable Inspection: Periodically check all cables for wear, damage, or loose connections. Replace damaged cables immediately.

- Inspect sensor connections.
- Reset the control box by turning it off and on, or using the R button if available for a soft reset.
If the problem persists after basic troubleshooting, contact a qualified service technician.
User Tips
- Actuator Compatibility: Please note that the POWERMAX ASD58-55 is a digital AC servo control box system. It typically functions as the controller for a separate servo motor (actuator) and does not include the motor itself. Ensure your servo motor is compatible with this control box.
- Parameter Backup: If your sewing machine has specific parameter settings, it is advisable to record them before making any significant changes or performing a factory reset.
