Circuit ID F
Circuit identification not possible
1
If generating mode is inhibited
(P076 = xx1), circuit identification is
not possible!
- Set P076 = x2
2
If
α
= 30°, not enough rectifier
current flows (less than 25% of the
rated DC current with
P160=150.0% or less than 10%
with P160=60.0%)
- Connection to DC link interrupted
3
P141 (Rectifier Induct.) and/or
P143 (Inverter Induct.) and/or P144
(C for DC link) could not be
identified
- Commutating inductance too low
(see Section 3.1)
- Connection to DC link interrupted
4
A waiting time of 20s has already
elapsed but the circuit identification
cannot be carried out because the
DC link voltage is too high
(Ud>20% of 1.35*P071)
- Another unit is supplying the DC
link
- Wait until the DC link has
discharged sufficiently, then start
circuit identification again
F091
Circuit ID C
Circuit identification or forming aborted
due to external cause.
If circuit identification is aborted, only
those parameters are modified whose
assignment was completed before this
fault occurred.

The abort took place because the
RUN or "R" status was exited for
some reason (e.g. brief power
outage) during forming or circuit
identification.
The abort took place because the
reserve data set selection changed
during forming or circuit
identification.
The abort took place because the
OFF command was given.
The abort took place because an
ON command was not given within
20 sec after selecting the forming
function (P052=20) or the circuit
identification function (P052=21)
The abort took place because the
"Inhibit regenerating" command
was given during circuit
identification (see control word 1,
bit 12 and P572)
