Specification: Item Type: Variable Frequency Drive Material: Flame Retardant ABS Model: SKI90-7D5G/011P-4 Input: 3PH AC380V±15% 20.5A 50-60Hz Output: 3PH AC0-380V 17.0A 0-400Hz Power Capacity: 11KVA Suitable Motor: 7.5KW 10HPOvervoltage Suppression Protection: When the bus voltage reaches or exceeds the bus overvoltage suppression point during the operation of the frequency converter, the frequency converter will automatically adjust the operating frequency to suppress the rise of the bus voltage, thereby ensuring that the frequency converter does not cause overvoltage protection due to excessive bus voltage. Overcurrent Suppression Protection: During operation, through real time monitoring of the load current, it automatically limits it to not exceed the set overcurrent suppression point to prevent fault tripping caused by excessive current. This function is particularly suitable for loads with large inertia or severe changes.TypeTerminal SignTerminal NameDescriptionPower Supply10V GNDExternal +10V Power SupplyExternal supply of +10V power supply, maximum output current: 150mA (with short circuit protection)Generally used as an external potentiometer working power supply,Potentiometer resistance range: 1-5kΩ24V COMExternal +24V Power SupplyExternal supply of +24V power, generally usedas digital input and output terminalsPower supply and external sensor power supplyMaximum output current: 200mAAnalog TerminalAl1 GNDAnalog Input Terminal 1Input Range: DC0-10V 0-20mA, determined by parameter P437Input Impedance: 22kΩ for voltage input, 500Ω for current inputAl2 GNDAnalog Input Terminal 2Input Range: DC0-10V 0-20mA, determined by parameter P4-37Input Impedance: voltage input impedance 22kQ, current input impedance 500ΩAO1 GNDAnalog Output Terminal 1Output Voltage Range: 0V-10VOutput Current Range: 0mA-20mA, 4-20mA (P5-23 selectable)AO2 GNDAnalog Output Terminal 2Output Voltage Range: 0V-10VNo current output functionJ1 jumper cap on isolated main control board to AO2 position, non isolated main control boardThe control board does not have this functionDigital InputX1 COMDigital Input 1HD1 (X5) can also be used as a high speed pulse input channel in addition to X1-X4 featuresMaximum input frequency: 50kHzInput impedance: 1kΩVoltage range at level input: 5V-30VX2 COMDigital Input 2X3 COMDigital Input 3X4 COMDigital Input 4HDI COM (X5 Terminal)Digital input 5High Speed Pulse Input TerminalA+ B-RS485 CommA+ is the positive input of the 485 communicationdifferential signal, B- is the negative input of the differential signalDigital OutputY1 COMOpen Collector OutputWhen used as a collector open circuit output terminal (J1 jumper cap on the 90 isolated main control board to the AO2 position)HDO COMHigh Speed Pulse OutputRestricted by the function code P5-00 HDO terminal output mode selection, output as a high speed pulse with a maximum frequency of 50kHz; When output as a collector open circuit, the same as Y1K1A K1B K1CRelay 1 TerminalContact Description: A: Common Point, B: Normally Closed Point, C: Normally Open PointContact Driving Capacity: AC250V, 3A; DC 30V, 1A.
