The inverter shell is made of industrial ABS material, which is heat-resistant, flame-retardant and impact-resistant, and has good safety. Comprehensive functions, can set frequency, V/F curve, torsion, control acceleration and deceleration, etc. With overload, over voltage, short circuit, protection, direct start and fault reset after booting. Design of keys and display, the operating data is clear at a glance, real-time attention to the running status of the inverter. Super all aluminum base heat sink combined with imported powerful fan, super wind power and good heat dissipation effect. Item Type: Frequency Inverter Model: A2-3040 Power 4KW Input: 3-phase 300-460V current 11A Input Frequency: 40-60HZ Output: 3-phase AC380V current 15.5A Output Frequency: 0-400HZ 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. 380V, power supply: 300-460V. 5-Digit Digital Display and Status Indicator. Display frequency, speed, CW and CCW status, fault, etc. 20-95% relative humidity (no condensation). 0.5G or less. Digital type: 0.01% (-10-50?); analog type: 0.1% (25±10?). Digital: 0.01Hz; Analog: 1% of the maximum operating frequency. Can be set directly by??? External voltage 0-5V, 0-10V, 0-20mA. Frequency lower limit, start frequency, can be set separately. Acceleration and Deceleration Control. Acceleration and deceleration time (0.01-650.00 seconds) arbitrarily selected. V/F curve can be set arbitrarily. Torsion boost can be set, the maximum 200.0% starting torsion is at 1.0Hz. 6 multi-function input terminals, realize 8-speed control, UP, DOWN function, external operation and other. A multi-function output terminal, can realize the indication and alarm during operation, frequency arrival, external abnormality, etc. Deceleration stop or free stop, DC brake, automatic reset and restart, etc. Drive (constant torsion 250%/1 minute, fan type 200%/1 minute). Momentary Power Failure Restart. Momentary power failure restart. Electronic circuit protection, U, V, W output short circuit protection. Heat sink overheat protection, reverse rotation limit, direct start and fault reset function after power-on, parameter lock, etc. 1 x Frequency Inverter. 1 x Chinese English User Manual.
