Advanced Speed Sensorless Vector Control Algorithm:

Speed sensorless vector control, can have lockedrotorrunning and output 150% rated torque at 0 Hz;

Own patent technology parameter identification method,can have accurate rotation or resting generator parameters
self-learning;Convenient adjustment, easy operation, providing higher control accuracy and response speed;

Apply to winding control, load distribution of multimotor working under the same loads etc.

Rotational speed tracking function

Own patent technology rotational speed tracking algorithm; speediness and smoothness, zero impact tracking generator free rotation speed, only used for MHMD centrifuge, induced draft fan, electromobile etc.

Torque and speed control superior performance

Speed control accuracy can arrive positive and negative 1rpm under 100% torque. Without sensor vector control, torque

response<20ms. With sensor vector control, torque response<5ms.< span="">

Apply to over 10000 turns high speed numerical control main axis.
Decelerate and stop, high performance, 0.1s fast and accurate stopping.
Apply to loads for precision machine tool, synchronized operation, oil pump etc.

Protect Machine’s torque limitation

VTP6 Variable-frequency Drive can provide torque limitation.When torque exceed the maximum torque that machine can
bear, Variable-frequency Drive will limit the torque to its setting maximum torque and protect the equipment's safety
more properly on the premise that the machine develop to the best efficiency.
Reliable torque limitation (torque limitation value 150%),adapt to loads of crane, extruder, etc.

Speediness current-limiting function can avoid Variablefrequency Drive's frequently overcurrent warning. When current exceed current protection point, speediness current-limiting funtion can limit current quickly in current protection point.

In this way, it can protect the equipment's safey and avoid overcurrent warning caused by impact load or other disturbs.

High Starting torque

VTP6 Series AC Drive can provide 150% starting torque at 0.5Hz (sensorless vector control), and 180% zero-speed torque (sensor vector control);

Apply to big starting resistance, fast accelerating and decelerating occasions, and loads for crane, puddling machine, blender, double housing planer, injection molding machine, extruder etc.
