Update rate Background
At power-up this parameter is zero. Each time the Regen drive is enabled the supply inductance is measured and displayed by this parameter. The
value given is only approximate, but will give an indication as whether the input inductance is correct for the sinusoidal rectifier unit size. The
measured value should include the supply inductance as well as the Regen drive input inductance, however, the supply filter capacitance, masks the
effect of the supply inductance. Therefore the value measured is usually the Regen drive input inductor value.

If an L.Sync trip occurs Pr 3.03 indicates the reason. At power-up and on trip reset this parameter is set to zero. Once an L.Sync trip has occurred this
parameter shows when the trip occurred and the reason for the last L.Sync trip as indicated by the bits in the table below. The reasons for the trip are
either because the supply frequency is out of range or the PLL (phase lock loop) within the drive cannot synchronise to the supply waveforms.
Bit
0 Tripped during synchronisation
1 Tripped while running
2 Reason for trip was supply frequency <30.0Hz
3 Reason for trip was supply frequency >100.0Hz
4 Reason for trip was PLL could not be synchronised

Pr 3.04 defines the action taken after enable and when a synchronisation failure occurs.
0, rESYnC: Continuously attempt to re-synchronise
1, del.triP: delayed trip
Attempt to synchronise for 30s. If unsuccessful after this time then give a LI.SYnC trip. After a failure during running attempt to re-synchronise for 30s
before tripping.
2, triP: immediate trip
Attempt to synchronise for 30s. If unsuccessful after this time then give a LI.SYnC trip. After a failure during running, trip immediately.
