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.

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.

The Delta VFD VJ Hybrid Servo Drive features the following capabilities:

  • 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


Delta VFD VJ Hybrid Servo Drive is especially compatible for use with Injection Molding machines.
