Delta: AC Motor Drives (VFD-VE Series)
With modern power electronics and advanced microprocessor technology, Delta's AC Motor Drives are able to efficiently control motor speed, improve machine automation and save energy. Taking advantage of our strong position in power electronics technology, Delta's VFD Series of AC motor Drives has evolved rapidly. Each Drive series is designed to meet specific application needs. Our AC Drives accurately control speed and torque, smoothly handle an increased load, and provide numerous custom control and configuration operating modes. Our AC Motor Drive product line provides a full range of motor control technologies and is used throughout a wide range of industries, to enhance and improve machine automation.
VFD-VE Series
This series adopts FOC (Field Oriented Control) which is a far more precise vector control algorithm. It can be used in both speed control and position control similar to a servo motor drive. The multi-function I/O terminal is expanded to meet users' various application needs. In addition, it is supplied with a Windows based PC software program for managing parameters and dynamic monitoring. It provides an excellent solution for load regulation. It can output 150% of rated torque at zero speed, and it can have "point to point" and relative distance control functions for position control, making it the best choice for challenging industrial control applications.
