Features: has all the features of the G3 G / P combination RS485/MODBUS standard the user can customize the V / F curve has a power down automatically memory set the frequency function parameter structural optimization, new application parameter group (E parameter) to improve analog input channel linearity optimize the internal structure, to enlarge the main power device capacity, enhanced cooling capacity, higher product reliability built-in PID regulator output DC 24V, 50mA DC 5V/10V,-10V control power supply both power function pulse input port identifiable 0.1Hz ~ 50kHz high-speed pulse or photoelectric encoder input signal built-in braking unit (18.5kW and below); built-in braking resistor (5.5kW and below) seven programmable input two set of programmable analog inputs the export and programmable relay output built-in timer and counter-10V to 10V bipolar control voltage analog input terminal (15kW and above) LCD & LED Chinese LCD and digital dual display control functions variety of control functions, such as multi-speed, PID control, instantaneous power failure restart, three-wire run, the program run, jump frequency and a variety of load characteristics of V / F curve, RS485 communication interface, pulse governor, multiple programmable input and output terminals for a variety of occasions. Strong stability circuit and process a wide range of protective and new components, to allow keyboard mounted remotely (farthest 10m); into the inverter speed control potentiometer on the keyboard are digitized, and significantly improve the whole anti-jamming capability ; perfect protection function, overload, overcurrent, overvoltage, undervoltage, short circuit, phase and power-off protection, safe and reliable. Low-noise operation available online to find the best balance point, noise and loss of PWM regulator can be readily adjusted to reduce noise, improve EMC performance, create the best operating environment. Energy efficient control operation, simple maintenance. High-performance general-purpose inverter products are widely used in various industries, to provide customers with a flexible, reliable, powerful drive. Precise control performance and high reliability, giving users the maximum benefits. Main function parameters: input power supply: three-phase 380V ± 10%, 50/60Hz output power: 0 ~ 380V/0.1Hz ~ 650Hz input signal (frequency setting); 0 10VCD, -10 to 10VDC
