Product Description

ES/EP
Hydraulic Servo System

The hydraulic servo drive system consists of ES600 series servo drive and EP series servo motor. By combining the capabilities of high-performance general servo platform, it comprehensively enhances servo motion control capabilities. Deeply coupled with the structural characteristics of oil pumps, it significantly reduces hydraulic pressure pulsation. The integrated machine features a duct casing structure, enhancing heat dissipation and increasing mechanical structural strength. With a new electromagnetic design featuring low inertia, the inertia of the frame size 200 is reduced by approximately 10%, meeting high-speed response requirements. By combining software and hardware, vibrations are minimized, achieving ultimate silence. Equipped with CANOPEN communication and coupled with upper computer platform, the entire electrical control solution assists in upgrading hydraulic equipment.

Paired with intelligent hydraulic position closed-loop algorithm, it significantly enhances positioning accuracy, reduces impact during operation, decreases equipment wear, and improves equipment lifespan. It intelligently diagnoses pump and oil circuit faults based on feedback pressure, actual speed, output current, and other information.

Product Advantages

More energy-efficient
High-efficiency servo drives and synchronous servo motors, combined with high volumetric efficiency hydraulic servo pumps, can eliminate energy losses due to overflow at high pressure in the hydraulic system, leading to energy savings of 40% to 80% compared to traditional asynchronous motor hydraulic systems.

More durable
Using a robust rotary transformer as the speed feedback component, it operates stably in environments with heavy metal dust, high temperatures, high air humidity, severe oil contamination, and significant vibration, ensuring stability, reliability, and extended lifespan of the component.

More user-friendly
Servo motors and drives require no maintenance, and signal acquisition from the upper computer is more user-friendly.

More stable
Designed with a large margin for strong protection capability, it significantly reduces the operating oil temperature of the entire machine.

More precise
It adopts the dual closed-loop control mode for more precise pressure and flow control.

Less noise
It reduces noise by more than 10DB compared to similar products.

More stable
Utilizing 32-bit ARM as the core and advanced motion vector core algorithm, it can operate without overcurrent or tripping under any acceleration and deceleration time and impact load conditions.

Higher performance
With real-time motor temperature monitoring, and built-in high-precision, high-response PID application algorithm module, it achieves precise pressure control, leading the 
industry in low-speed pressure holding performance. With a response time of 50ms when the pressure starts at 200bar, it has a pressure overshoot of 5bar, and a pressure fluctuation of 0.5bar. The weak magnetic range is improved by 10% compared to the previous generation, with enhanced response and impact suppression capabilities.

Higher integration
Rotary decoding card with integrated communication bus design.

Built-in braking unit
It is equipped with a built-in braking unit for applications in the hydraulic industry under 160KW.

   

Product Details

Working Principle
Before the system establishes pressure, the flow is used to control the speed of the servo motor precisely, thus controlling the system flow accurately.
After the system pressure is established, the real-time pressure is rapidly controlled through pressure PID, utilizing the advantages of fast response and precise control of the servo motor to achieve rapid and high-precision pressure control in the system.
