74 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 Torque Ref Sel
(3.15) respectively Aux Sp Ref Sel
(5.26) from Macro depend to Const
Zero.
75 RecoveryTime Recovery Time to short.
Increase Recovery Time (3.06) or
decrease Arm Cur Max (3.04) or
Overload Time (3.05).
76 Grp9 Disable 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.

tection of speed control parameters

90 Shortcut V11 Short circuit caused by V11
91 Shortcut V12 Short circuit caused by V12
92 Shortcut V13 Short circuit caused by V13
93 Shortcut V14 Short circuit caused by V14
94 Shortcut V15 Short circuit caused by V15
95 Shortcut V16 Short circuit caused by V16
96 Result False Result of block test unusable for a
clear diagnosis message but there is a
problem. A manual test has to be
made.

(b=bridge)
3bbbb 1…6 = thyr. V21…V26 faulty
3bbbb 1…6 = thyr. V21…V26 faulty

3bbbb 1…6 = thyr. V11…V16 faulty
3bbbb 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!

10903 faulty parameter address
10903 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)
