Motor Speed Controller

The description of the motorspeed controller in details as bellow: EC5000 series Frequency Converter integrates digital technology, computer technology, and modern auto-control technology. It has many merits like high accuracy, low noise, large torque, reliable performance. Therefore, it is applicable for industries like electron, machine, metallurgy, weaving, printing, petrol and, chemistry. It takes important in improving automatization level of industry, and gets high reputation from industrial members. 2. Parameters 1) Power range: 5.5 350KW 2) Voltage: 400 ±15% 3) Output frequency: 0.00 400.00Hz 4).current vector control,SVPWM VOLTAGE VVC,Central control module based on DSP,realizes high-speed and high performance control. 5).Integrate V/F control: 15 preset for V/F,programmable V/F mode 6).Frequency range:0.1 400Hz 7).Frequency setting:digital: 0.01Hz;analogue: highest frequency X 0.1%Hz 8).Instantaneous over current flowgeneral typeG:250% of inverter rated current flow exhaust fan,water pumpP: 200% of inverter rated current flow 9).Overload capacity: 150% rated current for 60s, 180% rated current for 10s 10).Overload protectionelectronic overheat relay protection 11).Radiator overheatthermal resistance protection 12).Speed up and down0.0∼3600second setting speed up and down seperately 13).Dead compensate function,realize low frequency and large output torque control. 14).Automatic slip compensate . 15).At most 8 steps speed control. 16).Internal PID function,realize high performance closed loop control. 17).Speed pursue starting and restart after momentary power loss. 18).Forced communicated function ,support standard RS485(max38400BPS) 19).High-efficient faults inquiry and record function ,conveniently obviate the fault. 20).paramater copy function. 21).Unique design,make frequency converter least pollution to the power. 22).Option for LCD/LED,9 core serial port of connection 23).Ambient temperature: -10 +45 degree(no freezing) 24).Avoid high temperature and moisture and avoid being wetted due to raining, with the humidity below 90%RH(not dewing,nohydrosphere).
