Features
· The function of time and power accumulation and display makes it more convenient for observing the energy saving effect.
· The unique time accumulation function can display the power running time for a single time and the accumulative running time.
· With RS485 communication internally installed (Please note when making orders),the frequency converter support standard MODBUS communication protocol and can be controlled by computer network.
· It is more convenient for automatic control with the multi-signal input and a simple PLC internally installed.
· The carrier frequency is adjustable with the maximum 15KHz, and the frequency converter can run without noise.
· The control modes are diversified with strong generability and wide applicability.
· With low speed and rated torque output, the frequency converter can reach 150% rated torque output when started at 10Hz with a stable operation.
· With the regulation function of PID internally installed, the closed loop control is simple.
· It is convenient to adjust the parameters by the keyboard.
· With the brake unit internally installed, the car can be stopped quickly(Please not when making orders).
· The operation state of fans can be controlled, which save more electricity and prolong the service life of easily damaged parts.
· With the display of diversified operation state parameters, the frequency converter makes it clear its state of signal control and load operation.
· Various cards with extension functions are available for you (PG card, communication card and tension control card).
