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.

Delta's Hybrid Energy Saving (HES) System provides precise pressure and flow controls for each injection molding process and also solves the energy waste issues of a traditional injection molding machine. This solution helps to improve product quality, market competitiveness and productivity.

 

Specifications

(1) Superior Energy-Saving Outcomes: Lower energy consumption rate at the clamping and cooling stage while providing high productivity and high precision. 40% less energy consumption compared to a variable pump hydraulic systems. 60% less energy consumption compared to a traditional quantitative pump hydraulic system.
(2) Low Oil Temperature: Oil temperature reduced by 5~10 oC; oil usage reduced by 50~60%; requires 50% less oil tank volume; lower cooler specifications required and for some cases cooler is not required.
(3) High Duplication Accuracy: Precise flow and pressure control featuring duplication of products with less than 0.09% difference.
(4) Long Holding pressure: Keeps mold halves securely closed for a longer period for thick plastic products formation.
(5) Good Frequency Response: When uses Delta HES with permanent magnetic servo motor (PMSM) speeds up frequency response to 50ms.
(6) Suitable for Harsh Environments: The resolver used in Delta HES is resistant to earthquakes, oil and dust.
(7) Old Machine Replenishment: Supports analog command 0~10V and linear correction (3 points), no replacing
(8) Flow Convergence: Saves cost on tubes, large flow capacity, enhances energy-saving.

A traditional drive system used for inertia load work generally performs rapid deceleration, braking and positioning. When its motor is in generator mode it produces large amounts of regenerative energy that must be consumed to maintain a stable DC bus voltage and safe operation. The traditional method to solve the regenerative energy problem is to install a brake resistor. While it is easy to install and is low cost, it takes up a large amount of space and requires installing additional devices to dissipate the heat. This method provides limited efficiency and wastes the regenerative energy.

Delta's REG2000 series is capable of collecting and converting your system's regenerative energy into reusable electricity for the ultimate in energy savings. The installation process is as simple as installing a brake resistor, but with only half the size and better efficiency. The REG2000 is your best green energy solution for power regeneration.
