The Convo Inverter CVF-S1 Instruction Manual provides essential details on wiring, safety, and parameter configuration. 1. Control Terminal Wiring
The CVF-S1 features several digital and analog input/output terminals for remote control: COM: Common port for digital signals.
S1 – S5: Multi-function digital inputs. By default, S1 is set to Forward (FWD) and S2 to Reverse (REV). S5 is typically used for an external Reset (RST).
AVI: 0–10V analog input for frequency setting via an external potentiometer.
ACI: 4–20mA analog input for external current-based speed control.
RA, RB, RC: Relay output terminals (AC 250V/3A) for status signals like "Fault" or "Running". 2. Key Parameter Settings
Programming involves entering the parameter code (e.g., F0.02) and modifying its value. Description Default / Range F0.02 Running command 0: Keypad control; 1: Terminal control F0.03 Frequency setting 0 (Panel Pot) 0: Panel; 3: AVI (0-10V); 5: ACI (4-20mA) F0.04 Max frequency Standard standard for acceleration/deceleration F0.05 Upper limit freq Prevents the motor from exceeding a safe speed F0.23 User's code Used for password protection (0-9999) 3. Operational Safety
Grounding: The ground terminal must be reliably grounded to prevent the risk of electric shock through the VFD housing.
Ventilation: Install the inverter in a well-ventilated environment to prevent overheating during operation.
Initialization: To restore factory settings, look for the parameter initialization code (often under group 'b' or 'H' in similar Convo series).
Detailed diagrams and full parameter lists are available in the Instruction Manual PDF hosted on Aliyun or through the Sigi-Elect archive.

Safety & Installation Precautions
High Voltage Danger: Do not touch terminals while the power is on; they carry dangerous high voltage.
Environment: Install in a dust-free, non-corrosive indoor environment with temperatures between 0∘C0 raised to the composed with power C +40∘Cpositive 40 raised to the composed with power C
Capacitors: Be aware that electrolytic capacitors inside the inverter can explode if burned or improperly handled during scrapping.
Maintenance: Always cut off the main circuit power before performing any check or maintenance work. 4. Troubleshooting Tips
If the drive "seizes up" or displays a fault code, refer to the following common solutions often cited in Convo troubleshooting guides:
Overcurrent/Overvoltage: Check the acceleration/deceleration times (Parameters F0.08 and F0.09) or verify that the motor load is not excessive.
No Display: Check input power and connection of the operation panel.

Chapter 8: Factory Reset – The "Panic Button"
If you have changed too many parameters and the motor behaves erratically, the manual provides a master reset:
- Ensure the inverter is stopped.
- Navigate to Parameter
F0.19. - Change the value from
0to1(Restore factory defaults, excluding motor parameters). - To restore everything (including motor parameters), set
F0.19 = 2. - Press
ENTER. The display flashes "8888" and resets.
Note: After resetting, you must re-enter the motor nameplate current (F1.01).
1. Overview and Safety Precautions
Before powering up the unit, the manual emphasizes several safety protocols. The CVF-S1 is an electrical device that deals with high voltages.
- Wait Time: After turning off the power, wait at least 5 to 10 minutes before touching internal components. The capacitors retain a dangerous high-voltage charge even after power is cut.
- Grounding: The unit must be grounded reliably to prevent electric shock and reduce electromagnetic interference (EMI).
- Motor Compatibility: Ensure the motor insulation is rated for inverter use, especially if running at high frequencies or long cable distances, to prevent insulation breakdown.
