V / F Motorsteuerung

WL-8000-3T-00550PV/FMotor Controller , Its specification is : 5.5KW 630KW,3 phase, 380V.special for all kinds of water-pumps Main Characteristics Adopt HITACHI 32-bit SCM, achieve optimized SPWM Control technology,High Torque and low noise . Output voltage is 50-100% of rated voltage, base frequency is 50-400Hz(2000Hz) ,both of them are adjustable . Input voltage is 3-phase, 220V, 380V, 460V, 660V, 15% . Auto energy-saving function, suit for all kinds energy-saving applications of constant speed and light loading. Having functions of Auto voltage regulation (AVR) and current-limited , to make sure the system reliable . Embedded PID controller, double keyboard display and could monitor both of supplied rate and feedback rate. Multiple kinds of Programmable input and output functions, intelligent multi-step speed control and Wobbling Frequency function. Functions of rotating speed tracing, and power-lost restart . Two kinds of Analog input interfaces, and could change over each other . Control way: SVPWM control Accuracy of output frequency: ±5% of Maximal frequency value Frequency set resolution: 0.01Hz : key-board 0.2Hz: Potentiometer analog input Voltage/ frequency : When voltage is 50%-100% of rated voltage, basic frequency 50-400Hz(2000Hz) is adjustable. Frequency of PWM carrier frequency: 1.080-16.00Hz Torque hoist: 34 kinds of way , optional Maximal output-power: 120% per minute, 150% moment trip Acceleration/deceleration: 0.1-9999S Rated output voltage: By using power-source voltage compensation function, and at motor rated voltage as 100%, could set within range of 50-100% (but output voltage could not be over input .) Auto voltage regulation: When electric-grid voltage is waving, keep V/F constant. Standard functions: Current limited, Torque hoist, Rotate-speed tracking and power-fail restart, Jumping frequency ,Frequency up-down limited control , Carrier-frequency regulation, Acceleration/deceleration time adjustable,Acceleration/deceleration mode variable , DC braking, Multi-step speed, Programmable operation,Wobbling operation, PID regulation control . Protection functions: Over-voltage, lower-voltage, current limited, over-current, over-load, Electronic thermal relay, over-heat, over-voltage stall, data protection,lower-load warning Frequency set input: Outer terminal V2: 0 10V , 0 5V Outer terminal A2: 4 20mA, 0 20mA, ( Z type is 0-1A) Signal feedback input: Outer terminal VF: 0 10V Outer terminal AF: 4 20mA, 0 20mA Input pointed signal: Forward run, reverse run, inch moving Outer output signal: Relay signal: 3A/250VAC Auxiliary signal output(open collector ) : 24VDC-50mA Cooling way: Forced air cooling Display: Function code , Data, Output frequency, set frequency, output current, input voltage, Motor speed, Forward-reverse run state, Over/lower-voltage, over-current/load/heat, over-voltage stall, Current-limited, data protection broken, active fault state, history fault.
