MC9001 220V 380V 0.75KW 4KW 5.5KWG 7.5KWP FREQUENCY CONVERTER Series
Frequency resolution: digital setting: 0.01Hz; simulation setting: maximum frequency 0.025% Overload capacity: 150% rated current for 60s shutdown (MC9001-4T4500G: 130% rated current running frt) Modulation mode: optimize the spatial voltage vector SVPWM modulation Control mode: open-loop vector control (SVC); closed-loop vector control (FVC); and V/ F control. Start-up torque: 0.25Hz/ 150% (SVC); OHz/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 acceleration and 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 action current 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 operation to prevent frequent overflow pressure trip. Simple PLC, multi-segment speed operation: up to 16 segments running through the built-in PLC or control terminals. Fast current limiting function: minimize the overcurrent fault and protect the normal operation of the frequency converter. Automatic Voltage Adjustment (AVR): When the power grid voltage changes, keep the output voltage constant Automatic energy saving operation: according to the load situation, automatically optimize the V/F curve to realize energy saving operation Torque limit and control: the "excavator" characteristic, to automatically limit the torque during the operation, to prevent frequent overcurrent trip; the vector control mode can realize the torque control.
