5. Nastavení a zapojení
Proper wiring is critical for the safe and correct operation of the VFD. Ensure all power is off before proceeding.
5.1 Basic Connection Diagram
The VFD supports both single-phase and three-phase 220V input. The output is always three-phase for motor control.
Obrázek 5.1: Simplified wiring diagram showing the connection from a circuit breaker to the VFD (R, S, T terminals) and then from the VFD (U, V, W terminals) to a three-phase motor. This illustrates a typical setup for connecting the VFD to power and a motor.
Obrázek 5.2: Detailed basic connection diagram for the HKS VFD. This schematic shows connections for single-phase 220V (R, T) or three-phase 220V (R, S, T) input, and three-phase output (U, V, W) to the motor. It also illustrates control terminals for FWD/STOP, REV/STOP, RESET, multi-speed inputs, digital frequency up/down, and external analog signal input (0-5V, 0-10V, 0-20mA) for frequency control via an external potentiometer.
- Vstupní výkon (R, S, T): Connect your 220V AC power supply. For single-phase input, connect to R and T terminals. For three-phase input, connect to R, S, and T terminals.
- Výkon motoru (U, V, W): Connect these terminals to your three-phase motor. Ensure the motor is rated for 220V three-phase operation.
- Základy: Always connect the ground terminal of the VFD to a reliable earth ground.
- Ovládací terminály: The VFD provides various control terminals for external start/stop, reverse, reset, multi-speed settings, and analog input for frequency control (e.g., with an external potentiometer). Refer to the detailed wiring diagram (Figure 5.2) for specific connections.
5.2 Initial Parameter Settings
After wiring, it is essential to configure basic parameters. Consult the full parameter list in the comprehensive manual for detailed settings. Common initial settings include:
- PN02: Set maximum output frequency (e.g., 50Hz or 60Hz depending on region).
- PN10: Set motor rated frequency.
- PN12: Set motor rated voltage.
- PN08 & PN09: Adjust acceleration and deceleration times. Default is 10 seconds.
If using an external potentiometer for frequency control, ensure the corresponding analog input parameters are correctly configured.

8. Řešení problémů
This section addresses common issues and their potential solutions. The VFD is equipped with various protection features that may trigger an error state.
8.1 běžné závady a jejich řešení
- Ochrana proti přetížení: If the motor draws excessive current, the VFD will trip. Check the motor load, ensure the motor is not jammed, and verify VFD power rating matches the motor.
- Přepětítage Protection (DC voltage > 400V): Nastane, pokud vstupní objemtage is too high or during rapid deceleration of a high-inertia load. Check input voltage and consider increasing deceleration time (PN09).
- Nízký objemtage Protection (DC voltage < 200V): Nastane, pokud vstupní objemtage drops below the acceptable range. Check input power supply.
- Ochrana proti zkratu: Indicates a short circuit in the motor or output wiring. Disconnect power and inspect motor and wiring for damage.
- Ochrana proti přehřátí: The VFD's internal temperature is too high. Check for blocked cooling vents, ensure proper ambient temperature, and verify the cooling fan is operational.
- Ochrana proti stání: The motor is unable to rotate or is heavily loaded. Reduce load or check for mechanical issues with the motor.
- Instantaneous Start / Overcurrent Error with External Switch: Some users have reported that when the VFD is set for start/stop by an external switch, the acceleration time parameter (PN08) may be ignored, leading to an instantaneous start and potential overcurrent errors. If this occurs, verify parameter settings and consider using panel control or consulting technical support for advanced configurations.
If a fault occurs, the ERROR indicator will illuminate. Press the STOP/RESET button to clear the fault after addressing the underlying issue.
