VFD-F Series

 

 

 

01 - 04

Mid-point Voltage

Factory Setting: 5.5/11.0

 

Settings

230V series: 0.1 ~ 255.0V

 

 

 

460V series: 0.2 ~ 510.0V

 

This parameter sets the Mid-point Voltage of the V/f curve.

 

This parameter must meet the following argument. Pr.1-02 >= Pr.1-04 >= Pr.1-06.

01 - 05

Minimum Output Frequency

Factory Setting: 1.50

 

Settings

0.10~20.00 Hz

 

This parameter sets the Minimum Output Frequency of the AC drive. This parameter must be lower than or equal to the Mid-point frequency

01 - 06

Minimum Output Voltage

Factory Setting: 5.5/11.0

 

Settings

230V series: 0.1

~ 50.0V

 

 

460V series: 0.2

~100.0V

This parameter sets the Minimum Output Voltage of the AC Drive. The parameter must be lower than or equal to the Mid-point Voltage.

01 - 07

Upper Bound Frequency

Factory Setting: 60.00

 

Settings

0.00~120.00 Hz

 

This parameter will limit the maximum output frequency of AC drive. If slip compensation (Pr.07-02~07-05) or feedback control (Pr.10-00~10-09) are enabled, the output frequency of AC drive may exceed the Master Frequency Command, but it will continue to be limited by this parameter setting.

01 - 08

Lower Bound Frequency

Factory Setting: 0.00

 

Settings

0.00~120.00 Hz

 

This parameter will limit the minimum output frequency. Any Master Frequency Command below Pr.1-08, will result in an output equal to Pr.1-08.

Upon a start command, the drive will accelerate from Pr.1-05 Minimum Output Frequency to the Master Frequency Command point.

The Lower Bound Frequency setting must be smaller than the Dwell Frequency (Pr.11-08>=01-08). If lower bound frequency setting is greater than the Dwell Frequency, the AC drive will equalize the two settings to the Lower Bound point.

VFD-F Series specifications

Delta Electronics has established itself as a leader in the production of Variable Frequency Drives (VFDs), and the VFD-F Series exemplifies their commitment to innovation and efficiency in motor control solutions. Designed for a wide range of applications, the VFD-F Series ensures seamless operation in various industrial settings, from pumps and fans to conveyor systems and HVAC equipment.

One of the primary features of the VFD-F Series is its compact design, which allows for easy integration into existing systems without consuming excessive space. This makes it an ideal choice for projects where space is limited. The series also boasts a high IP20 protection rating, ensuring that the drives are safeguarded against dust and accidental contact, contributing to their reliability and longevity.

The VFD-F Series utilizes advanced control technologies, including vector control and scalar control. Vector control provides precise torque and speed control, allowing for optimal performance under varying load conditions. This is particularly advantageous in applications requiring high accuracy, such as robotics and machine tools. The scalar control mode, on the other hand, is simpler and suitable for applications where precise control is not as critical.

Energy efficiency is a hallmark of the VFD-F Series. By allowing users to control motor speed and torque based on the actual demand, these drives can significantly reduce energy consumption compared to traditional fixed-speed motors. Coupled with Delta's energy-saving algorithms, the VFD-F Series not only promotes sustainable operation but also helps lower operational costs.

Another key characteristic of the VFD-F Series is its user-friendly interface. The intuitive control panel and programmable features enable quick setup and adjustments. Furthermore, the series supports multiple communication protocols, including Modbus, CANopen, and EtherCAT, which facilitate integration into various automation systems.

Safety features are paramount in the design of the VFD-F Series. It includes built-in protections against over-voltage, over-current, and overheating, ensuring safe operation in demanding environments. Additionally, its compliance with international safety standards underlines its reliability and robustness.

In summary, Delta Electronics' VFD-F Series stands out with its compact design, advanced control technologies, energy efficiency, user-friendly interface, and integral safety features. These characteristics make it a formidable solution for industries seeking high-performance motor control while maximizing efficiency and safety. As the demand for integrated and intelligent automation solutions grows, the VFD-F Series is well-positioned to meet these challenges head-on, reinforcing Delta Electronics’ reputation as a pioneer in the field.
