Faults and Alarms
Number / Alarm Cause
A069 Synchronizing is not started as long as the
ramp-function generator in the synchronizing
RGen active converter setpoint channel is active. This
alarm is only output if synchronizing is
selected.
A070 This alarm is output if the phase difference
goes outside the synchronizing window (P531)
Sync error after successful synchronization.
A071 An attempt has been made to start
synchronization with either the synchronizing
tSY missing board not inserted or not parameterized.
A075 The measured values of the leakage
measurement or of rotor resistance deviate
Ls, Rr Dev. significantly.
A076 The determined compensation time was
limited to the value range of 0.5 µs - 1.5 µs.
t-comp lim
A077 The measured resistance has been limited to
the maximum value of 49 %.
r-g limit
A078 The standstill measurement is executed when
the converter is powered up. The motor can
Stands. Meas align itself several times in a certain direction
with this measurement.
A079 The rotating measurement has been aborted
or cannot commence because an inverter stop
Mld Inv Stop command is present.
A080 When the converter is powered up, the
rotating measurement automatically
MotId:Dr.M accelerates the drive. The drive can then only
be externally controlled in a restricted fashion.
A081 The following description refers to the 1st
CBP. For other CBs or the TB see operating
CB alarm instructions for CB board.
The ID byte combinations which are being
sent from the DP master in the configuration
telegram are not in conformance with the
permissible ID byte combinations. (See also
Compendium, Chapter 8, Table 8.2-12).
Consequence:
No connection is made with the PROFIBUS
master.
A082 The following description refers to the 1st
CBP. For other CBs or the TB see the
CB alarm operating instructions for the CB board.
No valid PPO type can be identified from the
configuration telegram of the DP master.
Consequence:
No connection is made with the PROFIBUS
master.

Counter-measure
Wait until acceleration has been completed.
Check whether
- P462 Accel Time
- P463 Accel Time Unit have been correctly
set.
The alarm can only be deleted after
synchronization has been exited.
Insert the TSY board in the subrack
Usually the leakage reactance P122 is the
average value resulting from the measured
values in r546.1...12, and the rotor resistance
r126 from the values in r542.1..3.
If individual measured values significantly
deviate from the average values, they are
automatically not taken into account for the
calculation (for RI) or the value of the
automatic parameterization remains (for Ls).
It is only necessary to check the results for
their plausibility in the case of drives with high
requirements on torque or speed accuracy.
Converter output and motor output are too
different.
Check motor data input P095 to P109.
Converter output and motor output are too
different.
Check motor data input P095 to P109.
If the standstill measurement can be executed
without any danger:
- Power up the converter.
P561 Src InvRelese - Release the inverter
If necessary, re-start the measurement by
powering-up the converter.
If the rotating measurement can be executed
without any danger:
- Power up the converter.
New configuration necessary
