Delta VFD022E43A VFD-E Drive 3 HP 460V 3-Phase

VFD022E43A Delta VFD-E Sensorless Vector Drive with Built-in PLC

Product Introduction

The Delta VFD022E43A belongs to the VFD-E series, Delta's low-horsepower constant torque drive lineup. This model accepts a nominal input of 480 Volts AC with a range of 380 to 480 Volts AC. It operates with three-phase input and delivers 5.5 Amps of continuous current. The drive supports a maximum output frequency of 600 Hertz and utilizes sensorless vector control for superior motor performance. Unlike the VFD-EL series, this VFD-E model includes a built-in PLC function that allows users to write and execute simple Ladder Logic programs, making it highly versatile for various automation tasks.

Technical Specifications

This section details the core technical parameters of the Delta VFD022E43A drive. The input voltage range spans 380 to 480 Volts AC. Its continuous current rating is 5.5 Amps, and the power rating is 3 HP (2.25 kW). The control method uses open-loop vector (sensorless vector) control, which delivers superior torque performance compared to scalar control. Additionally, the braking system combines DC injection and dynamic braking, with the dynamic braking transistor already built into the unit.

The VFD-E series stands out with its modular design philosophy. Users can add various extension cards to expand functionality as needed. The built-in PLC function supports Ladder Logic programming with 2K steps capacity, enabling simple automation sequences without requiring an external PLC. An LED status indicator provides clear operational feedback. Note that the keypad comes separately, giving users the flexibility to choose the appropriate operator interface for their application.

Communication and Expansion Options

The VFD022E43A offers flexible communication and expansion capabilities through its modular design. Optional extension cards include PROFIBUS DP, DeviceNet, MODBUS TCP, EtherNet/IP, and CANopen. These options allow seamless integration into existing automation networks. The drive also supports multi-motor control and features a built-in RS-485 (Modbus) communication port as standard.

Furthermore, the modular design enables easy upgrades and customization. Users can select from various I/O extension cards to match specific application requirements. This flexibility reduces overall system costs and simplifies inventory management. The drive also supports pulse input and output for position control applications.

Mechanical and Environmental Parameters

Physical dimensions play a vital role in proper system integration. The VFD022E43A has a compact footprint of 3.94 inches (W) x 6.85 inches (H) x 5.35 inches (D). Its frame size is classified as "B" and it carries an IP20 enclosure rating, making it suitable for control cabinet installation. The gross weight of this unit is approximately 2.5 kg.

The drive operates efficiently in ambient temperatures ranging from -10°C to +50°C. Storage temperature extends from -20°C to +60°C. Relative humidity should remain below 90% (non-condensing). Additionally, vibration resistance is rated at 1G for frequencies under 60Hz, ensuring stable performance in industrial environments. This combination of moderate size and robust environmental tolerance makes the Delta VFD022E43A a dependable choice for many facilities.

Installation Guidelines

Installing the VFD-E series drive requires careful attention to mounting and wiring. First, ensure the mounting surface is flat and vertical for optimal heat dissipation. Use the provided mounting holes on the frame size B chassis to secure the unit. Maintain sufficient clearance around the drive—at least 50mm on both sides and 100mm above and below—for adequate airflow.

When wiring the Delta VFD022E43A, connect the three-phase input power to terminals R, S, and T. The motor leads should connect to terminals U, V, and W. For safety, ground the unit properly using the designated grounding terminal. Moreover, install the recommended fuses or circuit breakers on the input side to protect against short circuits. After wiring, connect the separately sold keypad to the drive and configure motor parameters before starting the motor.
