Built-in PID
It is convenient for forming closed loop control system,
applicable for course control like pressure and flow, etc.
Multi-speed operating
Realize multi-speed running by built-in PLC or control terminal.
Weaving wobble
frequency
Can get wobble frequency of adjustable central frequency
Auto voltage adjustment
When main voltage changes, the output voltage may be kept
constant by adjusting PWM output (AVR function).
Auto energy-saving
running
According to load condition, V/F curve can be optimized
automatically to get the aim of energy-saving running.
Auto current limiting
Limit in-service current automatically, so as to avoid tripping for
fault caused by frequent over current.
