3.2.5 Control Structure Closed Loop

The internal controller allows the drive to become a part of the controlled system. The drive receives a feedback signal from a sensor
in the system. It then compares this feedback to a setpoint reference value and determines the error, if any, between these 2 signals.
It then adjusts the speed of the motor to correct this error.
For example, consider a compressor application where the speed of the compressor is to be controlled to ensure a constant suction
pressure in an evaporator. The suction pressure value is supplied to the drive as the setpoint reference. A pressure sensor measures
the actual suction pressure in the evaporator and supplies the data to the drive as a feedback signal. If the feedback signal is greater
than the setpoint reference, the drive speeds up the compressor to reduce the pressure. In a similar way, if the suction pressure is
lower than the setpoint reference, the drive automatically slows down the compressor to increase the pressure.

Illustration 19: Control Structure Closed Loop

While the default values for the closed-loop controller of the drive often provide satisfactory performance, the control of the system
can often be optimized by adjusting parameters.

3.2.6 Feedback Conversion

In some applications, it may be useful to convert the feedback signal. One example of this is using a pressure signal to provide flow
feedback. Since the square root of pressure is proportional to flow, the square root of the pressure signal yields a value proportional
to the flow. See the following illustration.
