AC Drives, HMI & PLC Repair
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.
Sensorless Open and Closed Loop Vector AC Drive. The VFD-B series represents Delta's NEMA1 general purpose AC drive. The VFD-B series drive is rated to provide constant torque, featuring open and closed loop vector control. Delta offers an optional 2000 Hz high speed output that can be factory programmed at the customer's request.
Sensorless Vector AC Micro Drive. The VFD-E series represent Delta Electronics low horsepower, constant torque, IP20 rated Drive. Modular in design with flexible extension cards and a built-in PLC function, the E drive offers the ability to write and to execute simple Ladder Logic programs. This state-of-the-art series meets a full range of application requirements.
The VFD-F series is a Variable Torque rated AC Drive that was specifically designed for fan and pump applications ranging from 1 to 300 hp. This series offers the capability of connecting four motors at the same time and running them consecutively. PID, Sleep/Wake, and undercurrent protection are additional features of the VFD-F series drive allowing it to be used in many applications including: Air Conditioning Systems, Blowers, Fountains, Water/Wastewater Treatment Systems, and Ventilation Systems to name a few.
