First rate closedloop vector control (flux oriented control) variablefrequency drive (VFD, frequency inverter, VSD), strictly inspected,tested & controlled quality, strong performance, internationalstardards certified (CE, ABS, TUV, ISO...)
This closed loop vectorcontrol (field oriented control, flux oriented control, indirecttorque control) variable speed drive (AC drive), whose centralcontrol module based on DSP, realizes high-speed and highperformance control, achieves perfect motor control via servofunction, and offers comprehensive drive solution in motioncontrol. It''s suitable for large inertia, high accuracy, potentialenergy load, fast response and other high-end occasion.
Function of energy-savingcontrol, speed control, slip compensation, torque compensation,torque control, parameter copy and other high-endfunction.
4 control modesavailable: V/F control (scalar control), V/F with PG, seedlesssensor vector control (), vector control with PGcard.
Low-frequency large torque, 0.3Hz with the 180%torque output;
Powerful communication function, RS485/MODBUS standardinterfaces.
Dead zone compensate function and Automatic slip compensate, 180%torque output can come out below 0.5HZ frequency.
Eight switch inputs, three analog inputs, two analog output, 0-10Vor 0-20mA from inside the scope of the definition signal!
Support feedback signal: 0-10v, 1-5v, 0-20mA, 4-20mA
Built-in PID self-adjusting
Rotate speed tracking start and power-off reset function
High effective function on default record and recheck, easy trouble-shooting.
Unique EMC design minimizes pollute to electricityresource.
