LS580 Servo driver for plastic molding, pipe extrusion, shoe making, rubber, metal die casting 

Product Introduction


LS590 is specially designed for the permanent magnet synchronous servo motor (PMSM), and implements high-performance vector control on the motor. 

Integrating process control (such as precise control of injection speed and pressure holding) during the driving of the injection molding machine and stability control during cooperation with the injection molding machine controller, the LS590 series servo drive can well control the servo pump and provides general-purpose servo functions.

The LS590 is highly cost-effective and reliable. It is applicable to plastic molding, pipe extrusion, shoe making, rubber producing, and metal casting.

Application case


Mainly used for plastic molding, pipe extrusion, shoe making, rubber, metal die casting


Saving costs

Multi-pump confluence technology is connected in parallel to obtain large flow to drive large machines, reducing user input costs.Completely remove the proportional pressure valve and proportional flow valve as energy-consuming components,simplifying the hydraulic pipeline.
Built-in braking unit and braking resistor, reducing installation volume and cost.

Low noise

Under the excellent PID algorithm, the noise is much lower than that of the ordinary injection molding machine, and the noise of
the injection molding machine in the offline state is lower than 70 decibels, realizing silent operation

Extended service life

The oil temperature rise of the system is greatly reduced,so it is not necessary to reduce the use of cooling water,prolong the service life of hydraulic components, and protect the motor from over voltage, over current, and lack of other functions, and prolong the service life of the
machine.

Energy saving

The output flow of the traditional quantitative pump is a fixed value. When the load is small and the flow is required, the
excess flow depends on the proportional flow valve and the pressure valve to flow back to the mailbox. cause a lot of loss.
The hydraulic servo driver controls the oil pump to supply oil on demand according to the system voltage and flow requirements
to avoid loss and save electricity by 40% -65%, up to 80%



Superior performance

Vector control, fuzzy PID, pump leakage oil pressure compensation and other methods are used to ensure that the repeatability
of the injection position is less than ±0.3mm, and the pressure holding pressure fluctuation is less than ±0.5bar; the system
response time can be as low as 0.05s, which improves work efficiency , to improve the qualified rate of product molding.
The output current and output torque can be overloaded by 2.5 times the rated value, and it will not trip under high pressure
injection and heavy load impact, which will not affect production and ensure product quality.
