AI2 vs PTC
AI2
is set as
PTC
evaluation
and Ref-
erence
value source.
If
PTC
is allocated to
AI2
this input will
not be available
to other functions
anymore.
AI2
is normally parameter-
ized as a
reference
source for macro
1, 2, 4, 6, 7. Multiple setting is not
possible, alarm
Par Setting Conflict
(A16)
will be generated. Correct the
setting,
• set parameter

The digital inputs
DI1…DI4
of
macro
1, 5, 6, 7 and 8
are
re-configurable
in
parameter group
9-Macro Adapta-
tion
.
Macro 2, 3 and 4
are
not
re-
configurable. For these macros 2, 3
and 4
it is not possible to assign
any parameter in group 9. All pa-
rameters in this group
has to be
macro depend
. If there is anyone de-
fined different then macro depend
alarm
A16-Parameter Conflict
will
occur.

Thyristor diagnosis “con-
ductivity test”
After test of short circuit and earth fault a conductivitiy test of all
thyristors in pairs will be done. For that purpose all bridges are
tested one after the other. A faulty result will be shown as a
number of the affected thyristors.
e.g.
two
thyristors in
one
module!

Download failure
When downloading parameters from
panel to the drive the software at-
tempts to set the parameter. If the
value is actually not possible to set
(e.g. Min/Max check fails or drive is
switched on) the affected parameter
will be shown in coded form, e.g. pa-
rameter address 0903 corresponds to
9.03 (Jog 2)
