5.11 Group 10: PID Control Parameters

10 - 00 Input Terminal for PID Feedback

Settings

00: No function

 

01: Input via AVI

 

02: Input via ACI1

 

03: Input via ACI2

 

04: Input via External Reference

This parameter is to set the source of PID control feedback signal. The source could be AVI, ACI1, ACI2 or external reference that defined by 04-24.

When this parameter is set to 00, PID feedback control function is disabled.

When this parameter is set to 02/03 and analog input current of ACI1/ACI2 is lower than Pr.04-13/Pr.04-17, EF warning will pup-up.

If this parameter isn’t set to 00, AC drive will automatically start-up PID feedback control. Output frequency is calculated by master frequency and PID feedback signal.

Settings

00: Negative feedback control

 

 

 

01: Positive feedback control

 

This parameter could set the calculation method of deviation signal during PID feedback control circuit.

When this parameter is set to 00: when negative feedback control, the deviation equation is deviation = target value – detection signal. When increasing output frequency will increase detection value, this setting should be chose.

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.
