Figure 12 . Auto Recovery Operation (LMAT=RATT = 1 Step, ZENM=ZELM="1")
1
{
After completing the auto limitter operation, the auto recovery operation wait for only a period set by
WTM1-0. If the auto limitter operation is not occurred during the recovery operation, the auto recovery
operation is done only once.
IPGA is changed by zero crossing in the auto recovery operation, and the count of the next recovery
waiting period is also proceeding at the same time.
When the auto limitter operation is entered in zero crossing waiting(Rch), the auto recovery operation
in progress is stopped, the auto limitter is done according to smaller value (Rch in the Figure 10) of the
IPGA value. Then, IPGL is changed from 30H to 2EH and IPGR is changed from 2FH to 2EH.
(refer to Recovery Operation 1)
When the auto recovery operation is waiting for the next operation, the limitter operation is done from
IPGA value at that time . (refer to Recovery Operation 2)
