3KW Variable Frequency Drive 3PH AC380V Input 3PH AC0‑380V Output Support RS485 Communication Heavy Frequency Inverter Item Type: Variable Frequency Drive Material: Flame Retardant ABS Model: SKI90 3D0G 4 Input: 3PH AC380V±15% 10.5A 50-60Hz Output: 3PH AC0-380V 9.0A 0-400Hz Power Capacity: 5.9KVA Adaptive Motor: 3KW 5HP Category Terminal Symbol Segment Name Function Description Power Supply  10V GND External +10V power supply External supply of +10V power supply, maximum output current: 150mA (with short circuit protection), generally used as external potentiometer working power supply Potentiometer resistance range: 1-5kΩ  24V COM External +24V power supply External supply of +24V power supply, generally used as a working power supply and external sensor power supply for digital input and output terminals Maximum output current: 200mA Analog Terminal  Al1 GND Analog input terminal 1 1. Input range: DC0-10V 0-20mA, determined by parameter P437 No current output function The J1 jumper cap on the isolated main control board is at the AO2 position, while the non isolated main control board does not have this function Digital Input  X1 COM Digital input 1 In addition to the characteristics of X1 to X4, HD1 (X5) can also be used as a high speed pulse input channel. Maximum input frequency: 50kHz 1. Input impedance: 1k0  X2 COM Digital input 2  X3 COM Digital input 3  X4 COM Digital input 4  HDI COM (X5 Terminal) Digital input 5 High speed pulse input terminal  A+ B- RS485 communication A+ is the positive input of the 485 communication differential signal, and B- is the negative input of the differential signal Digital Output  Y1 COM Open collector output When used as a collector open circuit output terminal (J1 jumper cap on the 90 isolated main control board to the AO2 position)  HDO COM High speed pulse output Restricted by the function code P5-00 HDO terminal output mode selection, it is output as a high speed pulse with a maximum frequency of 50 kHz. When output as a collector open circuit, the specification is the same as Y1  K1A K1B K1C Relay 1 terminal Contact Description: A: Common point B: Normally closed point C: Normally open point Contact driving capacity: AC250V, 3A, C0S φ= 0.4 DC 30V, 1A  K2A K2B K2C Relay 2 terminal
