Parker AC30 series User Manual

Parameter Reference C-9
AC30 series Variable Speed Drive
Line Synchronisation
Typically the system will contain an AC30P/AC30D regen drive providing 4-Q power supply, and one or more drives on the common DC bus.
However, in order for the AFE control procedures to operate correctly, a synchronization of the IGBT firing sequence to the three phase mains
supply voltage frequency, angle, and direction of rotation need to be performed. This is achieved by using a line sync card (LA471892U001),
connected to a standard AC30 encoder option board (7004-04-00). Failure to successfully synchronise could cause significant supply distortion, poor
power factor, or even catastrophic failure.
