PLL (PHASE LOCKED LOOP)

The phase locked loop function block allows the drive to ride through short disturbances to the
supply voltage, frequency or phase and provides immunity to waveform distortion.
PLL (PHASE LOCKED LOOP)
Parameter
PLL STATE
Indicates the current operating state of the phase locked loop function block. Normally the PLL will reside in the LOCKED state after close of the
3-phase line contactor. The FAIL state results if the supply frequency moves beyond the acceptable operating range.
PHASE ERROR
The instantaneous angle error between the zero-crossing detection of the line supply and the reference output from the PLL function block.
PLL MAINS FREQ
The measured 3-phase line supply frequency at the output of the PLL function block.
