Product features compact structure and excellent performance

Wide voltage design in line with international standards

Meet the needs of 380-480V three-phase power grids including Europe, North America, India, etc.

High-performance vector control to improve equipment accuracy

The maximum output frequency under vector control is up to 500Hz, which can achieve high-precision speed output within 10 times the field weakening speed range.

Low speed and large torque (high starting torque)

In the closed-loop vector mode, the torque linearity deviation is within 3%, the torque output is stable, the low-frequency torque is large, and it can achieve ultra-low speed 0.01Hz stable driving with load. The torque mode and speed mode can be easily switched. Perfect DC braking circuit scheme.

Independent air duct design

The independent air duct design can effectively prevent dust from entering the inverter and cause short-circuit failures and improve reliability; the use of long-life cooling fans with large air volume can effectively reduce the temperature rise of the inverter and ensure the reliable and stable operation of the inverter.

Speed ​​start

It can avoid over-current faults caused by direct starting and realize smooth starting; it can reduce the impact of instantaneous power failure on production; it can reduce the impact on the power grid.

Intelligent energy saving function

Through the voltage flux vector algorithm, the closed-loop control of the output voltage is realized; when the motor torque requirement is low, the excitation current is reduced according to the load current; the motor efficiency is maximized; the motor loss is reduced, and the energy loss is reduced.

High-precision closed-loop control of multiple encoders

The MT550 series supports multiple encoder interfaces such as collector signal, differential signal, resolver signal, etc., which facilitates the realization of closed-loop vector control.

Wave-by-wave current limit

When the output current exceeds the wave-by-wave current limit point, the hardware current limit protection is triggered, which can restrain the rise of current to a certain extent, so that the current does not exceed the inverter protection value, and avoids shutdown due to sudden load or abnormal current causing current alarm.
