Features 1、The inverter shell is made of industrial flame‑retardant 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 real‑time 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 Drive Model: A2-3075 Power 7.5KW Input: 3-phase 300-460V current 20A Input Frequency: 40-60HZ Output: 3-phase AC380V current 30A Output Frequency: 0-400HZ Motor Control Method Key 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 sub‑item data modification. ◄►: Menu item content modification shift and panel jog button. Panel potentiometer: The operating frequency is given by the panel potentiometer. Display Window Content Meaning 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 Method Space voltage vector Input Power 380V, power supply: 300-460V 5-Digit Digital Display and Status Indicator Display frequency, speed, CW and CCW, fault, etc. Package List 1 x Variable Frequency Drive 1 x Chinese English User Manual
