Range of input voltage:180V~260V/320V~480V. It can drive the rated voltage 220V/380V three phase AC induction motor
Output frequency ranege:0~400hz
Output of low speed nominal torque, secure operation
Over-load/over-current/short-circuit/over-voltage/over-heating/over-torque protection function
Control mode: V/f control
Start-up torque:0.5HZ/150%(SVC)
PLC function(satisfying the controlling requirement of 15bit speed)
PID adjuster(respectively setting the proportion/ integral calculus/ differential coefficient of feedback signal)
Automatic energy-saving operation and display energy-saving data online
The carrier of frequency is adjustable continuously and it's up to 15KHz
Programmable input and output terminal for controlling
Control mode variable, great popularity
Internally brake is installed, and it can quickly brake
Internally adjustable function of PID is installed, simply closedloop control
Inner port is RS-485, it supports standard agreement of MODBUS, and it can be controlled by computer network
Built-in step(8step)speed control: PID control, travers control
AVR: can output constant voltage automatically when input voltage is fluctuating
6 multi-functional digital inputs(PNP&NPN),1 analog inputs,2 relay output,1 analog output,2 open collector output
QUICK/JOG function: users can look over the parameters which are different from the factory values
Speed tracing function: smoothly start the running motor
