1. Next-generation motor control platform
Capable of driving asynchronous and permanent magnet synchronous motors, supporting SVC and V/F control modes
2. Refined design with significant size reduction
With next-generation power device technology, it features high junction temperature, high power density and smaller dimension, reducing size up to 30% and installation area of 70%.
3. Optimized vector control technology, bringing breakthrough in motor control performance
SVC speed control ratio is increased to 1:1000; SVC replaces FVC when the output torque is greater than 10%; SVC winding and unwinding torque accuracy is ≤ 5%.
4. Fast current limiting
When exceeding the limit, the current can be quickly limited to within the limit, avoiding frequent overcurrent alarms caused by sudden loads or disturbances.
5. Unique speed tracking
Requiring no special hardware detection circuit, it can track the motor speed and direction quickly without any impact. It is especially suitable for fans, pumps and other equipment that requires speed tracking.
6. Overexcitation function
Rapid braking effect can be achieved without adding external brake resistors and other accessories;
It can suppress the rise of bus voltage during deceleration to avoid frequent over-voltage fault alarms. Additionally, it can brake quickly, meeting the requirement of quick stopping at shutdown.
7. Stable, reliable and long product life
Independent airduct design and standard coated PCB prevent dust and oil from entering the VFD and fully protect the electronic components on the PCB, thus ensuring longer service life and reliability.
8. Powerful upper computer monitoring software
Extensive background monitoring functions which facilitate on-site data collection and debugging; online oscilloscope function; batch uploading and downloading parameters; displaying Group U0 parameters in real time; and monitoring and diagnosis functions.
