A069
RGen active
Synchronizing is not started as long as the
ramp-function generator in the synchronizing
converter setpoint channel is active. This
alarm is only output if synchronizing is
selected.
Wait until acceleration has been completed.
Check whether
- P462 Accel Time
- P463 Accel Time Unit have been correctly
set.
A070
Sync error
This alarm is output if the phase difference
goes outside the synchronizing window (P531)
after successful synchronization.
The alarm can only be deleted after
synchronization has been exited.
A071
tSY missing
An attempt has been made to start
synchronization with either the synchronizing
board not inserted or not parameterized.
Insert the TSY board in the subrack
A075
Ls, Rr Dev.
The measured values of the leakage
measurement or of rotor resistance deviate
significantly.
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.
A076
t-comp lim
The determined compensation time was
limited to the value range of 0.5 µs - 1.5 µs.
Converter output and motor output are too
different.
Check motor data input P095 to P109.
A077
r-g limit
The measured resistance has been limited to
the maximum value of 49 %.
Converter output and motor output are too
different.
Check motor data input P095 to P109.
A078
Stands. Meas
The standstill measurement is executed when
the converter is powered up. The motor can
align itself several times in a certain direction
with this measurement.
If the standstill measurement can be executed
without any danger:
- Power up the converter.
A079
Mld Inv Stop
The rotating measurement has been aborted
or cannot commence because an inverter stop
command is present.
P561 Src InvRelese - Release the inverter
If necessary, re-start the measurement by
powering-up the converter.
A080
MotId:Dr.M
When the converter is powered up, the
rotating measurement automatically
accelerates the drive. The drive can then only
be externally controlled in a restricted fashion.
If the rotating measurement can be executed
without any danger:
- Power up the converter.
A081
CB alarm
The following description refers to the 1st
CBP. For other CBs or the TB see operating
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.
New configuration necessary
A082
CB alarm
The following description refers to the 1st
CBP. For other CBs or the TB see the
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.
New configuration necessary.
