2.7.6 Better Control
If a frequency converter is used for controlling the flow or pressure of a system, improved control is obtained.
A frequency converter can vary the speed of the fan or pump, thereby obtaining variable control of flow and pressure.
Furthermore, a frequency converter can quickly adapt the speed of the fan or pump to new flow or pressure conditions in the system.
Simple control of process (Flow, Level or Pressure) utilizing the built in PID control.
2.7.7 Cos
φ
Compensation
Generally speaking, a frequency converter with a cos
φ
of 1 provides power factor correction for the cos
φ
of the motor, which means that there is no need to
make allowance for the cos
φ
of the motor when sizing the power factor correction unit.
