Excellent performance

Speed Stable Precision:+/-0.5% rated synchronous speed(SVC)
Speed Adjustment Range: 1:100(SVC)
Torque Response:<20ms (SVC)
Heavy Load Overload Capacity: 110% rated stable operation,150% rated load 1min,180% rated load 3s
Low frequency large torque, under the open-loop vector model,can realise 0.5Hz loading (150% rated load) stable operation.
The drive can keep enough torque output capacity and no trip to run when there is instant mutation load.
Auto Current Limiting: Motor current can be controlled at a certain level does not affect the output torque.
Can accurately identify the motor parameters, realise high performance vector control.
Can realise static self-learning,dynamic self-learning, and adapt to different working condition requirement.
Can realise motor parameters accurate setting under the condition of long cable.
