Delta VFD110E43A VFD-E Series 15HP AC Drive

VFD110E43A 15HP 460V Sensorless Vector AC Drive

Product Introduction

The Delta VFD110E43A belongs to the trusted VFD-E Series of AC micro drives. This unit produces 15 Horsepower at 460 Volts AC with a rated output current of 24 Amps. It accepts a three-phase input and generates a three-phase output for precise motor speed control. Sensorless vector technology enables excellent torque performance without requiring an external encoder. Moreover, the built-in PLC function allows users to create and execute simple ladder logic programs directly on the drive. Additionally, the modular construction supports various extension cards, which enhances adaptability for different system requirements. Consequently, the VFD110E43A serves well in conveyors, pumps, fans, and many industrial machinery applications.

Technical Specifications

The VFD110E43A operates at a nominal 480 Volts AC, with a wide allowable range from 380 to 480 Volts AC. This drive achieves a maximum output frequency of 600 Hertz, making it suitable for high-speed motor applications. For motor control, it offers open-loop vector control as its primary mode, delivering accurate speed regulation across a broad range. Besides that, it also supports V/F control for standard general-purpose motor operation. For braking, the unit provides DC injection braking and dynamic braking capabilities. The dynamic braking transistor resides internally, so you do not need an additional external transistor module. This drive holds an IP20 enclosure rating, which makes it appropriate for installation inside industrial control cabinets. Its frame size is C, with compact dimensions of 10.24 inches in height, 4.57 inches in width, and 6.66 inches in depth.

Mechanical and Environmental Parameters

The Delta VFD110E43A functions reliably across a wide spectrum of environmental conditions. Its operating temperature spans from -10°C to +50°C, with derating necessary above 40°C for full load capacity. Storage temperatures can extend from -20°C to +60°C without damage. Furthermore, it withstands up to 95% relative humidity, non-condensing. The drive also meets IEC 60068-2-6 standards for vibration resistance, ensuring stable operation in light industrial environments. However, its IP20 rating indicates it is not waterproof, so it must reside inside a clean, dry, and well-ventilated control panel. The internal cooling fan and heatsink work together to dissipate heat efficiently. Therefore, maintaining adequate clearance around the unit remains critical for long-term performance and reliability.

Installation Guidance

Proper installation of the VFD110E43A ensures optimal operation and an extended service life. First, mount the drive vertically on a flat, non-flammable surface inside a suitable enclosure. Maintain a minimum clearance of 50mm above and below the unit to facilitate unrestricted airflow. Next, select appropriately sized wiring for the input power, motor output, and control terminals according to local electrical codes. The drive accepts three-phase input and outputs three-phase power to the connected motor. For control connections, you can utilize the terminal block, which supports digital and analog I/O alongside RS-485 communication. Additionally, installing an AC line reactor or EMI filter on the input side effectively reduces harmonic distortion and electrical noise. Finally, connect a dynamic braking resistor to the designated terminals if your application involves high-inertia loads requiring rapid deceleration. Always disconnect all power sources before performing any wiring or maintenance activities.

Frequently Asked Questions

Q1: Does the Delta VFD110E43A include a built-in keypad for operation?
A1: No, the digital keypad is an optional accessory and you must order it separately. Nevertheless, the drive features LED status indicators for basic monitoring, and you can also program it via RS-485 communication using a PC or a PLC.

Q2: Can I use the VFD110E43A with a single-phase power source?
A2: No, this model specifically requires a three-phase input supply for correct operation. Single-phase input may trigger under-voltage faults and significantly reduce performance.

Q3: What control modes does the Delta VFD110E43A support?
A3: This drive supports sensorless vector control for superior torque performance and V/F control for general-purpose applications. You can select your preferred mode through parameter settings based on your motor type and load characteristics.

Q4: Does the package come with a dynamic braking resistor?
A4: No, the braking resistor itself is not included in the package. However, the dynamic braking transistor is already built into the VFD110E43A. You only need to purchase an external resistor and connect it to the designated terminals.

Q5: Which communication protocols work with the Delta VFD110E43A?
A5: The drive supports Modbus RTU through its built-in RS-485 port. Additionally, you can add optional extension cards for other fieldbus protocols like Profibus, DeviceNet, or CANopen for broader system integration and networking.
