Description
The new hardware platform: Dual-CPU control solution, ARM(32bit)+DSP(16bit) The current vector control: Advanced field-oriented vector control algorithm accomplishes the full decoupling control to bring out authentic current vector control. The control mode is as following: High performance vector control (VC), sensorless vector control (SVC), torque control (TC). Modularization design: CHV100 supplies open the 2nd develop platform according to different characters of industries. There are some kinds of dedicated expansion card to fulfill assorted requirements.
