SPX inverter function parameters

●Control mode: open-loop vector control (SVC); closed-loop vector control (FVC); and V/ F control.

●Start-up torque:0.25Hz/ 150% (SVC); 0Hz / 180% (FVC).

●V / F curve: four ways: straight line; multi-point type; complete V/ F separation;incomplete V/ F

separation.

●Increase and deceleration curve: straight-line or S-curve increase and deceleration mode;Four accelerationand deceleration times, acceleration and deceleration time range 0.0~6500.0s.

●DC brake: DC brake starting frequency:0.00Hz~ maximum frequency;Brake time:0.0s~36.0s;Brake actioncurrent value: 0.0%~100.0%.

●Point movement control: point movement frequency range:0.00Hz~50.00Hz;

●Tap action, acceleration and deceleration time is 0.0s~6500.0s.

●Built-in PID: it can easily realize the process control closed-loop control system.

●Overvoltage and overvoltage loss speed control: automatically limit the current voltage during operationto prevent frequent overflow pressure trip.

●Simple PLC, multi-segment speed operation: up to 16 segments running through the built-inPLC or controlterminals.

●Fast current limiting function: minimize the overcurrent fault and protect the normal operation of thefrequency converter.

●Automatic Voltage Adjustment (AVR): When the power grid voltage changes, keep the output voltageconstant

●Automatic energy saving operation: according to the load situation, automatically optimize the V/ F curveto realize energy saving operation
