N300-300HF has the following features:
Powerful high torque performance has been accomplished using HHI`s advanced sensorless vector control.
■High starting torque of 200% or greater at 0.5 Hz
■Rotational fluctuation at low speed has been drastically reduced to enhance process stability and precision.
■High torque of 150% at approximately 0 Hz
High torque of 150% at approximately 0 Hz is accomplished when N300 drives a smaller motor by one frame size.
Brake ON/OFF sequence can be easily integrated with this feature.
■High torque multi-motor operation
Powerful operation is possible for two motors at the same time.
In the case of conventional sensorless vector control, only one motor can be controlled. (Note : The two motors must be the same model and capacity)
■On-line/off-line auto-tuning
Auto-tuning to perform sensorless vector control can now be easily done both on-line and off-line.
On-line auto-tuning makes it possible for the motor characteristics to be updated automatically under “real time” ambient conditions.
