Variable frequency inverter cabinet for driving motor for a farm
Frequency converter control panel function
1. the power switch and protection frequency converter panel are
equipped with low-voltage MCCB which is connected to the power
line, in addition to complete and disconnect the circuit, and also
against short-circuit, overload protection, cut off the power
2. Set frequency start, frequency stop button on start-stop control
function frequency conversion panel for the inverter operation
control, convenient to operate at site.
3. Set frequency adjustment potentiometer on frequency (speed)
adjustment Frequency converter panel, you can easily manually
adjust the inverter’s output frequency to control the motor speed
4. The table shows the voltage meter, ammeter, frequency meter and
various indicators such as power indication, alarm indication,
operation instruction and power frequency indication on the
inverter cabinet panel, and realize the input voltage, output
current, output frequency and various work of the inverter State
5. Standby frequency switching Users can choose frequency panel
which have the standby power frequency switching, when the inverter
fails, the motor through the automatic control circuit to switch to
power frequency power (this method can choose manual / automatic,
if frequency starting device greater than 15KW, use soft starter)
6. A variety of control functions can be set according to system
conditions on the inverter cabinet panel, through setting a variety
of control buttons and indicators such as forward, reverse, motor
speed, motor deceleration, jog forward, jog reverse, manual /
automatic, Emergency stop, frequency / frequency, PLC control,
touch screen and so on
7. Installation of external equipment according to the needs of the
operating conditions can be installed in the inverter cabinet,
including AC input reactor, the output reactor, DC reactor and EMI
filter, braking unit, braking resistor, contactors, intermediate
relays, thermal relay, programmable Controller (PLC), man-machine
interface (HMI), watt-hour meter, cooling fan etc.
8. Safety protection Install the VFD in the frequency control panel, can reduce
environmental pollution, reduce the risk of electric shock, will
have better protective effect.
9. Neat appearance to install the VFD in the frequency control panel, and other
low-voltage distribution cabinet with the same size, the same
color, to maintain power distribution facilities and control
equipment coordination, neat, beautiful.
