Product Application
Robot system
The robot system experiences changes in the optimal gains of the position loop and speed loop due to variations in the force radius of the mechanical arm and the load mass. The SED series products achieve adaptive adjustment of the optimal gains through real-time detection of the load’s rotational inertia, effectively minimizing the influence of the load’s rotational inertia.
Metal engraving and milling
For high-precision processing applications such as metal engraving machines, the servo drive system needs to have extremely precise feed control. The SED series is equipped with 23-bit optical encoders, with a response frequency of up to 3.2kHz, which can perfectly produce smooth mirror-like effects.
High-speed Soldering Machine
The SED series products are also commonly used in high-speed pick-and-place machines that require rapid reciprocating movements. This equipment demands that the servo drive system possess high-speed return, extremely short positioning time, and anti-shake during position arrival, etc. The SED series can meet the needs of the efficient electronic manufacturing industry.
Adaptive adjustment of control gain parameters for current loop, speed loop and position loop
The SED series can automatically generate the optimal current loop control parameters based on the electrical parameters of the motor. It can also automatically adjust the gain parameters of the speed and position loops as well as the damping filter parameters for different transmission types, different system rotational inertia, and different processing stages. Customers only need to set the necessary processing-related parameters such as transmission type, electronic gear ratio, and processing speed. Compared with fixed gain parameters, the processing effect of the new algorithm has been significantly improved.
Set-up time comparison
Compared with the conventional fixed gain parameters, in addition to the aforementioned improvement in processing effect, the positioning time is also significantly shortened under different mechanical transmission types, with the maximum reduction reaching over 60%.
Response bandwidth comparison
The SED series features a FOC calculation duration of less than 1us. The current loop response bandwidth reaches the industry-leading level, while the speed loop’s ultimate bandwidth can reach up to 3.2kHz. The position command follows more quickly. The ultra-high-speed and ultra-precise control of the servo system will maximize the potential of mechanical equipment and enhance customer benefits.
