A044
I too low
Only for synchronous motors (P095=12) in
operation:
The difference smoothed with P159 between
excitation current setpoint and actual value
(r160 - r156) deviates from zero by more than
25% of the rated magnetizing current.
Only for synchronous motors P095=12)
Check:
- whether the current limitation of the excitation
current control is too small,
- whether the dynamic performance of the
excitation current injection is too low,
- whether the excitation current injection
function is operating,
- whether the wiring of excitation current
actual-value P155 is correct,
- whether the wiring of excitation current
setpoint r160 is correct,
- whether there is a wire break between
MASTERDRIVES and the excitation device,
- whether the voltage limitation is too low for
dynamic excitation current control,
- whether the analog output for r160 takes
place without isolating amplifiers (despite
cable length > 4 m)
A045
DC braking activated
The DC braking function has been activated
and the motor frequency is still above the
frequency at which DC braking begins (P398).
- Increase frequency at which DC braking
begins
A049
No slave
not Compact PLUS
At serial I/O (SCB1 with SCI1/2), no slave is
connected or fiber-optic cable is interrupted or
slaves are without voltage.
P690 SSCI AnaIn Conf
- Check slave.
- Check cable.
A050
Slave incorrect
not Compact PLUS
At ser. I/O the slaves required according to a
parameterized configuration are not present
(slave number or slave type): Analog inputs or
outputs or digital inputs or outputs have been
parameterized which are not physically
present.
Check parameter P693 (analog outputs), P698
(digital outputs). Check connectors
K4101...K4103, K4201...K4203 (analog inputs)
and binectors B4100...B4115, B4120...B4135,
B4200...B4215, B4220...B4235 (digital inputs)
for connecting.
A051
Peer baud rate
not Compact PLUS
In a peer-to-peer connection a baud rate has
been selected which is too high or too
different.
Adjust the baud rate in conjunction with the
SCB boards P701 SCom/SCB Baud Rate
A052
Peer PcD L
not Compact PLUS
In a peer-to-peer connection, a PcD length has
been set which is too high (>5).
Reduce number of words P703 SCom/SCB
PcD #
A053
Peer Lng f.
not Compact PLUS
In a peer-to-peer connection, the pcD length of
transmitter and receiver do not match.
Adjust the word length for transmitter and
receiver

A057
TB Param
not Compact PLUS
Occurs when a TB is logged on and present,
but parameter tasks from the PMU, SCom1 or
SCom2 have not been answered by the TB
within 6 seconds.
Replace TB configuration (software)
A061

A062
Alarm 2
Function blocks
An active signal is present at binector U066
(1).
