4. Spesifikasies

The following table outlines the key technical specifications for the HLTNC HS320 VFD (0.75KW, 380V, 0-400Hz variant).

5. Installasie

5.1 Montering

• Mount the VFD vertically on a sturdy, non-combustible surface.
• Ensure adequate ventilation space around the unit (typically 10cm above and below, 5cm on sides) for proper heat dissipation.
• Avoid mounting in direct sunlight, near heat sources, or in areas subject to vibration.
• Use appropriate screws and mounting hardware to secure the VFD firmly.

5.2 Bedrading

All wiring must comply with local and national electrical codes. Use appropriate wire gauges for the VFD's power rating.

5.2.1 Power Input (R, S, T)

• Connect the 380V AC three-phase power supply to the R, S, and T terminals.
• Install an appropriate circuit breaker or fuse upstream for protection.

5.2.2 Motor Output (U, V, W)

• Connect the three-phase motor to the U, V, and W output terminals.
• Ensure the motor's rated voltage and current are compatible with the VFD.

5.2.3 Grounding (PE)

• Connect the VFD's grounding terminal (PE) to a reliable earth ground. This is critical for safety and EMI reduction.

5.2.4 Beheerterminale

The VFD provides various control terminals for external start/stop, speed reference (analog input), multi-function inputs, and relay outputs. Refer to the detailed wiring diagram in the full product manual for specific terminal assignments and functions. Common connections include:

• Analoog invoer: For external speed control via potentiometer or 0-10V/4-20mA signal.
• Digitale insette: For external start, stop, forward/reverse, multi-step speed commands.
• Aflos uitsette: For fault indication or run status.

6. Operasie

6.1 Beheerpaneelfunksies

• Digitale skerm: Shows frequency, output current, voltage, and parameter codes.
• RUN-knoppie: Begin die motor.
• STOP/RES Button: Stops the motor or resets a fault.
• PRG/SET Button: Enters/exits parameter setting mode, confirms parameter changes.
• JOG/ESC Button: Initiates JOG operation (momentary run) or exits a menu without saving.
• Op/af pyle: Navigate through parameters or adjust values.

6.2 Basiese Bedieningsstappe

1. Krag aan: Apply power to the VFD. The display will light up.
2. Stel frekwensie: Use the Up/Down arrows to set the desired output frequency.
3. Begin Motor: Druk die HARDLOOP knoppie. Die motor sal versnel tot die ingestelde frekwensie.
4. Stop Motor: Druk die STOP/RES knoppie. Die motor sal vertraag en stop.

7. Parameterinstellings

The HLTNC HS320 VFD has a comprehensive set of parameters to customize its operation. Accessing and modifying these parameters allows fine-tuning for specific applications.

7.1 Entering Parameter Mode

1. Druk die PRG/SET button to enter parameter setting mode. The display will show a parameter group code (e.g., P00).
2. Use the Up/Down arrows to navigate through parameter groups (e.g., P00, P01, P02, etc.).
3. Druk PRG/SET again to enter a specific parameter within a group (e.g., P00.01).

7.2 Modifying Parameters

1. Once a specific parameter is selected, use the Up/Down arrows to change its value.
2. Druk PRG/SET to save the new value. The display may flash to confirm.
3. Druk JOG/ESC to exit the current parameter or group without saving changes.

7.3 Important Parameters (Examphulle)

• P00.01 (Max Output Frequency): Sets the maximum frequency the VFD can output.
• P00.03 (Acceleration Time): Defines the time it takes for the motor to accelerate from 0Hz to the maximum frequency.
• P00.04 (Deceleration Time): Defines the time it takes for the motor to decelerate from the maximum frequency to 0Hz.
• P00.05 (Rated Motor Frequency): Set to the motor's nominal frequency.
• P00.06 (Rated Motor Voltage): Set to the motor's nominal voltage.
