Product Description

The Allen Bradley PowerFlex 523 Vector Control VFD drive
control which is a sensorless feedback control based on the "model" of the motor operating parameters
in its memory. As the motor operates, the 523 monitors the output current and compares it to the "models"
and determines from experience what the different current effects mean in terms of the motors
performance. It will then execute the necessary error corrections with the voltage and frequency to
maintain various motor speeds under various loads. Vector drive technology will provide excellent slow
speed motor control.

A standard (non-vector) VFD drive has no way to compensate or modify its output with the changes in the
load especially when the speed reference gets reduced. This is especially true at speeds below 10 Hz.
