3.2 Components
The V350 series VFD typically consists of:
- Control Panel: For parameter setting and status display.
- Power Terminals: For connecting input power and motor.
- Control Terminals: For external control signals (e.g., start/stop, speed reference, fault output).
- Heat Sink and Fan: For cooling the internal components.
4. Setup and Installation
4.1 Mounting
Mount the VFD vertically on a non-flammable surface, ensuring adequate clearance for ventilation. Avoid mounting in direct sunlight or near heat sources. Maintain specified clearances above, below, and to the sides of the unit for proper airflow.
4.2 Wiring
All wiring must comply with local and national electrical codes. Use appropriate wire gauges and ensure all connections are secure.
- Power Input (R, S, T): Connect the 380V AC power supply to the R, S, T terminals. Ensure correct phase sequence.
- Motor Output (U, V, W): Connect the motor to the U, V, W terminals. Do not connect power factor correction capacitors or surge suppressors between the VFD and the motor.
- Grounding (PE): Connect the PE terminal to a reliable earth ground.
- Control Terminals: Wire control signals (e.g., start/stop, analog speed reference, digital inputs) according to your application requirements and the VFD's terminal diagram. Refer to the detailed wiring diagram in the full product manual for specific terminal assignments.
4.3 Initial Power-Up
Before applying power, double-check all wiring connections. Power on the VFD and observe the display. If any fault codes appear, refer to the troubleshooting section.
5. Operating Instructions
5.1 Control Panel Operation
The VFD features a 5-digit two-line LED display and a keypad for parameter setting and monitoring. Common buttons include:
- RUN/STOP: Starts and stops the motor.
- PROG/DATA: Enters/exits parameter setting mode and confirms data.
- UP/DOWN Arrows: Navigates through parameters and adjusts values.
- SHIFT: Moves cursor during parameter editing.
5.2 Basic Parameter Settings
Key parameters to configure for initial operation include:
- Motor Rated Frequency: Set to the motor's nominal frequency (e.g., 50Hz or 60Hz).
- Motor Rated Voltage: Set to the motor's nominal voltage (e.g., 380V).
- Motor Rated Current: Set to the motor's nominal current.
- Acceleration Time: Time taken for the motor to accelerate from 0Hz to maximum frequency.
- Deceleration Time: Time taken for the motor to decelerate from maximum frequency to 0Hz.
- Control Mode: Select between open-loop vector, closed-loop vector, or V/F control based on application requirements.
Refer to the detailed parameter list in the comprehensive manual for advanced settings and specific parameter codes.
6. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your VFD.
- Cleaning: Periodically clean the VFD's exterior and ventilation openings to prevent dust accumulation. Use a soft, dry cloth. Do not use liquid cleaners.
- Inspection: Regularly inspect wiring connections for tightness and signs of wear or damage. Check for any unusual noises or odors during operation.
- Ventilation: Ensure cooling fans are operating correctly and that airflow around the unit is unobstructed. Replace fans if they become noisy or stop working.
- Capacitor Check: For long-term reliability, electrolytic capacitors may require inspection or replacement after several years of operation. This should be performed by qualified service personnel.
7. Troubleshooting
This section provides solutions for common issues. For persistent or complex problems, contact technical support.
| Fault Code/Symptom | Possible Cause | Solution |
|---|---|---|
| OV (Overvoltage) | Input voltage too high, regenerative braking. | Check input voltage. Increase deceleration time. Install braking resistor if necessary. |
| OC (Overcurrent) | Motor overload, short circuit, rapid acceleration/deceleration. | Check motor load. Inspect motor and wiring. Increase acceleration/deceleration time. |
| OL (Overload) | Motor or VFD overload. | Reduce motor load. Check motor current settings. Ensure proper ventilation. |
| UV (Undervoltage) | Input voltage too low. | Check input power supply voltage. |
| Err (External Fault) | External fault input activated. | Check external control circuit and devices connected to fault input terminals. |
