K0250 Flt/Warn # Connector for current alarm number
and current fault number.
Upper byte: fault number
Lower byte: alarm number.
The value 0 means that no alarm or
fault is present. Attention: The alarm
number and the fault number are not
updated at the same time as the fault
or warning bit in the status word; they
are staggered a few sampling periods.

Short-Time I2t This connector provides information
on the status of the short-time I2t
monitoring. This monitoring is always
active whenever the current quantity
exceeds 1.6 times the converter rated
current (I_Conv_Rated). The
integrator does not return until the
current quantity falls below 0.9
I_Conv_Rated. If the connector
achieves the value 100%, the current
limit (r129) is reduced to 0.9
I_Conv_Rated.

K0257 SoL.Rec.ActErr Connector for output of the current
error value of the LC receiver block:
The connector is reset to 0 with a 0->1
edge of binector B0241, and as long
as binector B0241=1, if a sign of life is
omitted the connector is incremented
by 10, and if a valid sign of life is
received the connector is
decremented by 1.

counter is reset only when the power
supply for the electronics (24V) is
switched on.
