3PH Frequency Converter AC400V Input AC0 to 400V Output Motor Speed Converter 37KW 3 Phase Variable Frequency Drive Item Type: Frequency Converter Material: Aluminum alloy Model: SKI90 037G or 045P 4 Input: 3PH AC400V±15％ 76A 50 to 60Hz Output: 3PH AC0 to 400V 75A 0 to 400Hz Power Supply Capacity: 57KVA Adaptable Motor: 37KW 50HP Category Terminal Symbols Segment Name Function Description Power Supply 10V GND External positive 10V power supply Provide positive 10V power supply to the outside Maximum output current: 150mA (with short circuit protection) Generally used as an external potentiometer working power supply Potentiometer resistance range: 1kΩ to 5kΩ 24V COM External positive 24V power supply Provide external positive 24V power supply, generally used for digital input and output terminals. Power supply and external sensor power supply Maximum output current: 200mA Analog Terminal Al1 GND Analog input Input terminal 1 1. Input range: DC0V to 10V or 0mA to 20mA, determined by parameter P437 Input terminal 2 1. Input range: DC0V to 10V or 0mA to 20mA, determined by parameter P4 37 Output current range: 0mA to 20mA, 4 to 20mA (P5 23 can be selected) AO2 GND Analog Output No current output function J1 jumper cap on isolated main control board to AO2 position, non isolated main control board does not have this function. Digital Inputs X1 COM Digital input 1 HD1 (X5) has the features of X1 to X4, but also can be used as a high speed pulse input channel 1. Input impedance: 1k0 (X5 terminal) Digital input 5 High speed pulse input terminal A positive B negative RS485 communication A positive is the positive input for 485 communication differential signal, B negative is the negative input for differential signal Digital Output Y1 COM Open collector output When used as open collector output terminal (J1 jumper cap to AO2 position on the 90 isolated type main control board) HDO COM High speed pulse output Bound by function code P5 00 "HDO terminal output mode selection" when used as high speed pulse output up to 50kHz. When used as open collector output, same as Y1 specification.
