08 - 00

DC Brake Current Level

Factory Setting:

00

 

Settings

00~100%

Unit: 1

This parameter determines the level of DC brake current output.

 

 

 

 

 

 

08 - 01

DC Brake Time during Start-up

Factory Setting:

0.0

 

Settings

0.0~60.0 Sec

Unit:

0.1

This parameter determines the duration of time that the DC brake current will be applied to the motor during the AC drive start-up.

The motor may rotate by external force or inertia itself before operating. It may damage the motor or start the AC drive protection function by an over current if the AC drive added at this time. This parameter enable the AC drive to output a direct current before running the motor that will produce a torque to forced motor stop and get a steady start-up characteristic.

08 - 02 DC Brake Time during Stopping

Settings 0.00~60.00 SecUnit: 0.01 This parameter determines the duration of time that the DC brake current will be applied to the motor during stopping.

Motor may be in rotation status after AC drive stops output and can’t in stop status accuracy when motor is running with external force or itself inertia. After AC drive stops output, this parameter could output a DC current to produce torque force motor to stop and make sure the motor has stopped accuracy.

08 - 03 Start-point for DC Brake

Settings 0.00~120.00 HzUnit: 0.01 This parameter determines the frequency when DC brake will begin during deceleration.

If this parameter is set greater than 01-05 minimum frequency setting, it won’t decelerate to 01-05 and enter DC brake status when AC drive brakes. Suitable DC brake start-up frequency setting will get better brake characteristic.

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.
