Multi-section speed run
Realized by inbuilt PLC or control terminal; with 15 section speed, each section speed with separate acceleration and decelaration  time; with inbuilt PLC can achieve reserve when power down
Inbuilt PID controller
Convenient to make closed-loop control system
Automatic energy saving run
Optimize V/F curve automatically to achieve power saving run according to the load status
Automatic voltage regulate  (AVR)
Automatically keep output voltage constant, when the power saving run according to the load status
Automatic current limitingCurrent limited automatically under run mode in avoid of inverter over-current frequently to trip
Carrier modulationModulate carrier wave automatically according to the load characteristic
Speed tracking restartmake rotating motor smoothly start without shocking
Running function
Running command specified channelKeypad specified, control terminal specified, communication specified can switch through various means
Running frequency specified channel
Main & auxiliary specified to a realize one main adjusting and one fine control. Digital specified, analog specified, pulse specified, pulse width specified, communication specified and others, which can be switched by many means at any time
Binding function
Run command channel and frequency specified channel can bind together randomly and switch synchronously
Input output characteristicDigital input channelChannel 8 for universal digital input, max. frequency 1KHz, channel 1 can be used as pulse input channel, max. Input 50KHz which can be expanded to channel 14.
Analog input channel
Channel 2 for analog input channel, AI1 can choose 4~20mA or 0~10V output, AI2 is differentialinput channel, 4~20mA or -10~10V for option, which can be expanded to channel 4 analog input
Pulse output channel
0.1~20KHZ pulse spare signal output to achieve setting frequency, output frequency and other physical quantity output
Analog output channelChannel 2 for analog signal output, AO1can choose 4~20mA or 0-10V, AO2 can choose 4~20 mA or 0~10V to achieve setting frequency, output frequency and other physical quantity  output, which can be expanded to channel 14 analog output
Unique characteristic
Rapid current limit
Limit inverter over current to the greatest point and make it run more stably
