According to the application characteristics of 710-1200KW high-power motors, a special product developed which is using parallel dynamic current sharing technology of IGBT modules. The unique heat dissipation design fully meets the heat dissipation problem of high-power frequency conversion, and guarantees cost performance at the same time.
Easy to install and debug
Solid EMC design, unique radiator shape.
Adopt modular design
The main control system uses 32-bit high-speed DSP, integrated PG-free vector control, V/f control, and torque control.
The optimized motor parameter identification model can effectively reduce the sensitivity to motor parameters and make self-learning more accurate.
High starting torque: 150% of starting torque can be provided when it is at 0.5Hz;
Fast dynamic response: Under the vector control mode without PG, the dynamic response time is less than 20ms;
Built-in PID regulator can easily form a closed-loop control system for process quantities such as temperature, pressure and flow.
It has automatic fault reset and power-off reset functions to ensure continuous production and production efficiency.
Perfect protection functions: overvoltage/under-voltage protection, inverter overheat protection, ground fault protection, short circuit protection, overcurrent protection, overload protection, etc.
