Delta VFD007E43T VFD-E 1 HP AC Drive

VFD007E43T Delta 460V 3-Phase Variable Frequency Drive

Product Introduction

The Delta VFD007E43T belongs to the versatile VFD-E series of AC micro drives. Specifically, this model supports a 1 HP (0.75 kW) motor capacity and operates on a 460V three-phase input. Meanwhile, it delivers a rated current of 2.5 Amps and achieves a maximum output frequency of 600 Hz.

Engineered for low-horsepower constant torque applications, this drive employs sensorless vector control technology. Consequently, it ensures excellent starting torque and precise speed regulation across a wide operating range. Furthermore, the unit features an integrated fan cooling system and an IP20 enclosure, making it suitable for panel mounting in controlled industrial environments.

Moreover, the VFD007E43T includes a built-in PLC function that allows users to write and execute simple Ladder Logic programs directly on the drive. In addition, its modular architecture supports various extension cards, offering great flexibility for system integration. Therefore, this compact drive delivers reliable motor control while occupying minimal panel space.

Technical Specifications

The Delta VFD007E43T features a lightweight and compact design that simplifies handling and installation. Besides, its small footprint makes it ideal for machinery with limited mounting space. Meanwhile, this drive is designed for indoor use only, protected from direct moisture, oil mist, and corrosive gases.

Installation and Mounting Guide

Correct installation ensures the reliability and service life of the VFD007E43T. For best results, follow these recommended procedures:

1. Mounting Surface : Install vertically on a flat, non-flammable mounting plate. Use the four mounting holes provided for secure attachment.

2. Clearance : Maintain at least 50 mm clearance above and below the drive for proper airflow. Additionally, side clearance of 30 mm is also required for adequate ventilation.

3. Environmental Protection : Avoid high-temperature areas, direct sunlight, or locations with excessive vibration or dust. Otherwise, performance may degrade over time.

4. Wiring Practices : Use shielded cables for control and motor connections. Moreover, separate power input and motor output wiring to minimize electromagnetic interference.

5. Grounding : Securely connect the ground terminal to the system earth ground for safety and noise reduction.

Ensure the input power is disconnected before installation. Furthermore, always verify that the motor nameplate matches the drive specifications.
