Inverter DELTA VE/VL/VJ SERIES

Features​
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.​

VFD-VJ Series

The Delta Hybrid Servo Drive VFD-VJ Series is designed with AC servo technology to drive hydraulic systems with perfect control of the drive, motor and hydraulic unit.

Specifications

  • Field Oriented Control
  • Suitable for both synchronous servo motors and asynchronous servo motors
  • Built-in brake unit (up to 22kW)
  • RS-485 communication interface (RJ-45) and standard MODBUS communication protocol
  • Precise current detection for system protection with safety ensured
  • New software for PC connection allows real time monitoring of AC motor drive status

Structure of a Hybrid Servo System

  • When pressure and flow instructions are given to the injection molding machine, the Delta VFD-VJ series begins PID calculation simultaneously to attain the actual pressure and speed feedback data, and drive the servo motor and the hydraulic pump. The Delta VFD-VJ series offers you a system with fast response and high duplication accuracy.
