Yaskawa 3G3HV-A4022-CE 400V AC Drive

The Yaskawa 3G3HV-A4022-CE is a high‑performance AC drive (inverter) from the 3G3HV series, specifically designed for HVAC (Heating, Ventilation, and Air Conditioning) and general‑purpose motor control applications. This compact drive provides variable speed control for three‑phase induction motors rated at 2.2 kW (3 HP) with a 400 V AC input supply. It offers both V/f and sensorless vector control modes, enabling precise speed regulation and high starting torque for pumps, fans, compressors, and conveyor systems.

The drive features a built‑in EMC filter (CE marked), a PID controller for closed‑loop process regulation, and a simple, menu‑driven keypad for local operation and parameterization. Its compact design and side‑by‑side mounting capability save valuable panel space. The 3G3HV‑A4022‑CE also includes communication options (Modbus RTU via RS‑485) for integration into PLC‑based control networks.

Key Functional Features

• Energy saving mode: The drive automatically optimizes the motor voltage based on the load, reducing energy consumption in fan and pump applications.

• PID sleep/wake function: The drive can stop the motor when the process variable reaches the setpoint, and restart when the error exceeds a configured deadband, improving system efficiency.

• Fault ride‑through: The drive continues operation through momentary voltage dips, preventing process interruptions.

• Motor thermal protection: Built‑in PTC thermistor input and motor overload protection (via I²t calculation).

• Copy unit supported: Parameters can be copied to other drives for quick setup.

Typical Applications

• Fans and blowers: Variable air flow control in HVAC systems.

• Centrifugal pumps: Pressure and flow regulation in water supply and irrigation.

• Small compressors: Speed control for constant pressure air supply.

• Conveyors: Speed matching in material handling systems.

Installation and Wiring

Mount the drive vertically on a flat, non‑flammable surface, maintaining the specified clearances (100 mm above/below). Use shielded cables for the control terminals and ensure the motor cable length does not exceed the recommended distance (typically 50 meters for unshielded, 30 meters for shielded). Connect the mains supply to the R/S/T terminals and the motor to U/V/W. The grounding terminal must be connected to the panel earth with low impedance. The control terminals are grouped for easy wiring; use ferrules on all wire ends. After installation, perform the motor auto‑tuning function to optimize the drive parameters for the specific motor.

Standards and Compliance

The 3G3HV‑A4022‑CE is CE certified (EMC and LVD), UL listed, and RoHS compliant. It meets the requirements of EN 61800‑3 for EMC and EN 61800‑5‑1 for safety.

Conclusion

The Yaskawa 3G3HV‑A4022‑CE AC drive is a versatile, reliable, and energy‑efficient solution for motor control in HVAC and light industrial applications. Its compact footprint, comprehensive protection, and built‑in control functions make it a practical choice for system integrators and machine builders.
