Features of Estun servo.
High overload capacity.
The capacity of the industrial-grade intelligent power module IPM selected for the EDB/EDC servo drive is larger than that of similar servo products that are usually calibrated with the same power, and has the characteristics of strong overload capacity, strong anti-load disturbance ability, and large starting torque. The servo drive can ensure that the overload capacity below 1.5KW is generally 3 times, and the overload capacity above 2KW may reach 2.5 times.
Standard.
The latest high-speed digital signal processor DSP is applied to meet the control requirements of high-speed and high-precision servo. The active interference control and speed observation control algorithms, combined with the feedforward control to compensate for the servo delay, and the instruction smoothing technology, have better dynamic tracking and stability performance than the traditional PI control, and achieve high response, high precision, high speed and high reliability of the servo. Equipped with automatic inertia recognition, it is more convenient to adjust.
Communication interfaces.
The EDC servos have a standard CAN bus interface for easy integration into distributed control systems. At the same time, based on the Modbus protocol of RS485 or RS232 interface, the host computer can be connected to 32 servos for network control, with a maximum transmission distance of 1200 meters (RS485), and can also communicate with PLS, DCS, intelligent instruments, touch screens and other equipment to achieve centralized monitoring.
Flexibility and.
The EDB servo drive integrates position control, speed control, and torque control, and can dynamically switch between various control modes. More flexibility to use.
Communication software.
This can be achieved with dedicated computer software:
Parameter management - all parameters can be edited, transferred, compared, and initialized, which is convenient and fast. Monitoring - All input/output signals, current alarms and history, and system status can be monitored in real-time. Real-time sampling - Waveforms that can make the acquisition of speed and torque easy to debug and analyze. Commissioning - The gain of the servo drive can be quickly adjusted, and it is easy to test without position or speed commands.

Estun Servo Motor - Introduction to Servo Motor Inertia Knowledge
1. What is "inertia matching"?
1. According to Newton's second law: "The required moment T of the feed system = the transmission inertia of the system J×angular acceleration θ angle". The acceleration θ affects the dynamic characteristics of the system, the smaller θ, the more time from the controller to the completion of the system's execution.
