frequency: 020Hz,operating voltage level: 020%,operating time:
settable within 020s
Jogging frequency range: 0.1Hz50.00Hz,jogging acceleration and
deceleration time: 0.13600s.
It is convenient for forming closed loop control system, applicable
for course control like pressure and flow, etc.
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.
Sensorless vector control
150% output of torque at 1Hz, rev accuracy: 0.1%
Motor parameters automatic read
Reading the parameters from motor when completely stop in order to
achieve optimal controlling effect.
Running command passage
Setting of operating manual; setting of control terminal; setting
of serial port; switching by three ways
