400HP AC Motor Drive Controller

400HP AC Motor Drive Controller 380V 400Hz for Spindle motor

EM15 is a new-generation inverter developed independently by EMHEATER, featuring low noise, hight performance and multiple functions. It adopts the rotor field-oriented vector control strategy to realize high-accuracy, wide-range speed and torque control of the motor.

Product features

Support various motor's control mode
Support V/F control, Sensor-less vector control and Closed-loop vector control.
Support several of encoder.

Fast current limit function
Fast current limit function prevents the inverter frequently over current alarm. When the current exceeds the protection points, fast current limit function can quickly limit current below protection point to protect the safety of equipment, and to avoid over-current alarm caused by suddenly adding load or interference.
