Adopt DSP control system, Achieve speed-less sensor vector control, able to suppress the low-frequency shock effectively.
Main used for blower and water pump which is highly accuracy of speed and torque response and the low frequency occasions.
  • Description
Three Control Modes: Sensor-less vector control (SVC), V / F control, torque control;
Starting Torque: Sensor-less vector control : 0.5Hz / 150% (SVC);
Optional built-in DC reactor helps 18.5KW-90KW inverter to improve the input power factor measurement, overall efficiency and stability;
0.75-15KW  built-in brake unit, for quick stop, braking resistor can be connected directly;
16 segments Simple PLC, multi-speed control and PID control; 
Supports multiple frequency setting: Digital ; Analog ; PID ; Communication etc;
Support START and STOP DC Breaking ;
Input and output terminals are freely programmable, user can combine variety of operating modes based on working needs ;
Jump frequency control function to avoid mechanical resonance, make the system more stable and reliable;
Non-stop function after momentary power failure;
Wake-up delay setting;   Over-torque detection;
Variety of up-Limit frequency setting source selection;
Able to u se two-way shift function key to view real-time parameters;
