DC braking Be optional during both starting and stopping, the operating frequency: 0∼20Hz,operating voltage level: 0∼20%,operating time: settable within 0∼20sJoggingJogging frequency range: 0.1Hz∼50.00Hz,jogging acceleration and deceleration time: 0.1∼6000s.Built-in PIIt is convenient for forming closed loop control system, applicable for course control like pressure and flow, etc.Multi-speed operatingRealize multi-speed running by built-in PLC or control terminal.Weaving wobble frequencyCan get wobble frequency of adjustable central frequency Auto voltage adjustmentWhen main voltage changes, the output voltage may be kept constant by adjusting PWM output (AVR function). Auto energy-saving runningAccording to load condition, V/F curve can be optimized automatically to get the aim of energy-saving running.Auto current limitingLimit in-service current automatically, so as to avoid tripping for fault caused by frequent over current. Running functionRunning command passageSetting of operating manual; setting of control terminal; setting of serial port; switching by three ways. Frequency setting passageSetting of keyboard analog potentiometer; setting of keyboard , keys; setting of functional code digits; setting of serial port, setting of terminal UP/DOWN, setting of analog voltage, setting of analog current ; setting of impulse, setting of combination; switching at any time by kinds of setting ways. Switch input passage Forward/reverse rotating command, 6-way programmable switching value input to set 21 functions. Analog input passage2-way analog signal input, 4∼20mA, 0∼10V optional. Analog output passage Analog signal output 0∼10V to get output of physical quantity like frequency and output frequency Switch output passage 2-way programmable open collector output; 1-way relay output signal, to get output of different physical quantities.
