Accelerate/Decelerate curve Two modes:linear Acc/Dec, S curve Acc/Dec;seven kinds of Acc/Dec time (Maximum:6000 minutes) and unit(minute or second) is selectable. DC braking Initial frequency of DC braking:0 15.00Hz Braking time:0 60.0s Braking current:0 80% Power consumption braking Power consumption unit inside, can be connected with external braking resistor Jog Range of jog frequency:0.1Hz 50.00Hz, Acc/Dec time of jog operation 0.1 60.0s. Internal PI Be able to form close loop control system easily. Multi-step speed running Multi-step speed running can be realized by internal PLC or control terminals Textile wobble frequency Adjustable preset frequency and center frequency Auto voltage regulation (AVR)When the power system voltage changes, maintain the constant of output voltage Auto energy saving mode V/F curve is optimized automatically according to the load condition to realize energy saving operation Auto current limiting running current is limited automatically to avoid trip caused by over-current Fix-length control The frequency inverter will stop when reaching the fixed length Communication function With RS485 port, support Modbus-RTU protocol. Be with master-slave multi-devices linkage function Running function Command mode Operated by three mode: digital panel, control terminal, serial port Frequency setting mode Setting modes can be selected ,including: potentiometer setting mode, & keys setting mode, digital function code setting mode; serial port setting mode,UP/DOWN terminal setting mode;analog voltage setting;analog current setting; pulse setting;combination setting; Digital input channel Forward/Reverse running command;6 channels programmable digital input,can set 35 kinds of function,X6 support 0 20KHz pulse output Analog input channel channel analog input ,4 20mA and 0 10V can be selected Analog output channel 1 channel analog output,4 20mA,0 10V can be selected. digital output channel Programmable open-collector output,1 channel; relay output signal ,1 channel Digital panel LED Display indicate parameters: frequency ,output voltage, output current and so on. connected device display Indicate physical quantities, such as output frequency, output current ,output voltage and so on key Lock Lock all the keys Parameter Copy Copy function parameters between two inverters by remote control(developing) protect function Over current protection;over voltage protection;under voltage protection;over heat protection;over load protection Option partsextension cable of digital panel; brake resistor.
