Feature:1. The inverter shell is made of industrial flameretardant ABS plastic, which has good heat resistance and impact resistance.2. Comprehensive functions, with common functions of current mainstream inverters, suitable for a variety of occasions.3. Humanized keyboard design, clear digital screen display, convenient operation and realtime understanding of running status.4. Super all aluminum base heat sink combined with imported powerful fan, super wind power and good heat dissipation effect.5. With frequency and acceleration deceleration control and multiple protection functions, it is widely used in machine tool equipment, automation equipment and other fields.Specification:Item Type: Variable Frequency DriveModel: A2-3075Power 7.5KWInput: 3-phase 300-460V current 20AInput Frequency: 40-60HZOutput: 3-phase AC380V current 30AOutput Frequency: 0-400HZMotor Control MethodKey Operation Instructions:RUN/STOP: When the inverter is in idle state, press this key and the inverter will start running, and when it is pressed again, the inverter will stop running.STOP/RESET: When the inverter is running, press this key and the inverter will stop running. If the inverter is in a fault state, press this key to reset the inverter. In the menu setting, press this key to return to the previous menu.REV: Press this key to reverse the running direction of the inverter. It is also effective at runtime.SET: Press this key to enter the menu setting. If it is in the menu item, press this key to save the menu parameter and enter the next menu item.: Menu item selection and subitem data modification.: Menu item content modification shift and panel jog button.Panel potentiometer: The operating frequency is given by the panel potentiometer.Display Window ContentMeaning of Display Status:ERROR: Inverter fault indicator. When the light is on, it indicates that the inverter is abnormal.FWD: Forward rotation status indicator, when the light is on, it indicates that the inverter is running forward.REV: Reversal status indicator, when the light is on, it means the inverter is reversed.ANALOG: Analog reference indicator, when the light is on, it means that the running frequency comes from the analog quantity.SEGMENT: The segment speed setting indicator, when the light is on, it means that the running frequency comes from the segment speed.PANEL: Panel control indicator, when the light is on, it means that the running signal is given by the panel.Digital tube: Indication of inverter operating frequency. The nixie tube flashes when the inverter stops, and the actual value is the given frequency of the inverter. The display data during frequency operation is determined by the "Pn01" data.Motor Control MethodSpace voltage vectorInput Power380V, power supply: 300-460V5-Digit Digital Display and Status IndicatorDisplay frequency, speed, CW and CCW, fault, etc.Communication ControlRS-232Operating Temperature-10-50Humidity20-95% relative humidity (no condensation)Vibration0.5G or lessFrequency ControlRange0.10-180.00HzAccurayDigital type: 0.01% (-10-50); analog type: 0.1% (2510)Set ResolutionDigital: 0.01Hz; Analog: 1% of the maximum operating frequencyOutput Resolution0.01HzKeyboard Setting MethodCan be set directly by Analog Setting MethodExternal voltage 0-5V, 0-10V, 0-20mAOther FunctionsFrequency lower limit, start frequency, can be set separatelyGeneral ControlAcceleration and Deceleration ControlAcceleration and deceleration time (0.01-650.00 seconds) arbitrarily selectedV/F CurveV/F curve can be set arbitrarilyTorsion ControlTorsion boost can be set, the maximum 200.0% starting torsion is at 1.0HzMulti-Function Input6 multi-function input terminals, realize 8-speed control, UP, DOWN function, external operation and otherMulti-Function OutputA multi-function output terminal, can realize the indication and alarm during operation, frequency arrival, external abnormality, etc.Other FunctionsDeceleration stop or free stop, DC brake, automatic reset and restart, etc.Protective FunctionOverload ProtectionDrive (constant torsion 250%/1 minute, fan type 200%/1 minute)FUSE ProtectionFUSE blown, motor stoppedOvervoltageDC voltage800VUndervoltageDC voltage280VMomentary Power Failure RestartMomentary power failure restartOutput Short CircuitElectronic circuit protection, U, V, W output short circuit protectionOther FunctionsHeat sink overheat protection, reverse rotation limit, direct start and fault reset function after power-on, parameter lock, etc..Package List:1 x Variable Frequency Drive1 x Chinese English User Manual
