FC155 series frequency inverter has the following features:

FC155 Series AC drive Features
Multiple Control Modes:
*Supports multiple control modes: vector V/F control, sensorless vector speed control,
sensorless vector torque control, sensor vector speed control and sensor vector torque
control .
Advanced Vector Control Algorithm:
*The optimized VF control and sensorless vector control is more stable at low speed,
more powerful in the ability of low frequency torque output and with better dynamic
response and both the sensorless vector and sensor vector mode support speed
control and torque control.

Our Frequency Inverter Solution on Fan And Pumps

1, Load feature
  (1)  Both of them belong to fluid control.
  (2) If without VFD, the fluid is controlled by valve or baffles;
  (3) For less fluid required system, there will be more energy saving.
  (4) In theory, if the running frequency is H1, then
        Energy Saving = 1-(H1/50)3

2,  Requests for frequency inverters (VFD)
  (1) Soft start the motor, reduce the surge current.
  (2) VFD should work continuously without fault.
  (3) Speed tracking and start (flying start) function should be reliable.
  (4) In some systems, PID function is required.

3,  Real example
 In a hotel, there is an central air-conditioner, the cooling fan is one PCS of 15kW motor, in one year,
