WL-9000-3T-Z frequency inverter, Its specification is : 5.5KW 630KW,3 phase, 380V.special forInjection Molding Machine,(Plastic Machines) Main Characteristics Special design only for Injection Molding Machine, no need to change original control way, oil circuit and circuit structure of equipment, very convenient installing and using ; Strong current -shock resistance, could bear high shocking current up to 2.5 times of rated current at a moment, and high over-load ability of normally operating for 10 seconds under the current of 1.8 times of rated current, to make sure no trip when strong current-shock and momentary heavy-load. Good Soft starting function, rapid current control ability. The fastest acceleration time is about 0.2S. Having functions of Fault-Auto-reset and Tracking-starting , make sure the quality and continuity of producing. Various of signal input: control ways of 0-1A, 0-5V, 0-10V, 4-20MA, 0-20MA , could connect externally with Signal EXNET expansion plate, multi-channel input at the same time, and control the injection machine exactly. Good energy-saving effect, the rate of energy-saving is up to 25%-65%; Z type of frequency inverter has two circuits of Energy-saving and Industrial-frequency, also has Signal Indication, could make sure produce normally even Energy-saving circuit 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: 200% per minute, 250% 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. Application Range: All Dosing Pumps using Proportional Valve to control oil circuit system------like Injection Molding Machine, Die Casting Machine, Blow Molding Machine of Single or Multi-pump system , Injection Machine of Single or Double-motor . Energy-saving rate is about 25%-65% . All Dosing Pumps using Directional Valve to control oil circuit system----like Hydraulic press Machine, Big-size punch. Also for the drive of Worm Air Compressor
