EA(LA)90C servo controller
The EA (LA) 90C series is an integrated controller for energy-saving transformation of injection molding machines. It uses vector control technology to control the speed and torque of AC asynchronous motor effectively and without delay by driving the internal speed and current closed-loop control.


Specification
feature

1.Excellent current vector control technology, with 0.1s instruction plus deceleration, driver stable running without fault
2.Low frequency and large torque output: starting with 0.25Hz, 180% rated torque, running without tripping
3.Low noise operation: low harmonic PWM drive mode, the motor full speed section is smooth and no noise
4.The low, middle and high speed output torque is stable and the fluctuation range is small, which can make the pressure of the injection molding machine stable and ensure the quality of the process.
5.Frequency conversion control to ensure normal production
6.the power saving rate is up to 25~70%.
7.Easy to install and connection, easy to maintain
