22.5.4 3368 Vfcatchsearchtime s FLOAT 2.0 1.0 10.0 ERW V
This parameter is used to congure the speed at which the output frequency changes for synchronisation with the
motor running. It represents the time in which the frequency would change from 50 Hz to zero if the output current
were equal to the drive continuous current.
The default setting is correct for most applications.
Low values require high current levels but guarantee fast synchronisation.
High values require low current levels but synchronisation takes longer.
During the synchronisation procedure the motor may change its speed of rotation. The longer the synchronisation
phase the more evident the change in the speed of rotation.

22.5.5 3370 VfcatchPgain perc FLOAT 10.0 0.0 100.0 ERW V
This parameter is used to set the proportional gain of the current regulator used by the procedure to capture a motor
that is running. Values that are too low could trigger the Overcurrent protection. Changing this value is not recom-
mended.

22.5.6 3372 VfcatchItime ms UINT16 200 200 1000 ERW V
This parameter is used to set the integral time of the current regulator used by the procedure to capture a motor that
is running. Changing this value is not recommended.

22.5.7 3376 Vfcatchlastrefdly ms UINT16 0 0 30000 ERWZ V
This parameter is used to set the time within which the drive must be enabled in order to start the capture procedure
at the output frequency present before disabling the drive. If the time that elapses from the moment the drive is disa-
bled exceeds the time set in this parameter, the capture procedure starts from the frequency set in parameter 3364
Vfcatchstartfreq.
