Number / Alarm Cause
A044 Only for synchronous motors (P095=12) in
operation:
I too low 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.
A045 The DC braking function has been activated
and the motor frequency is still above the
DC braking activated frequency at which DC braking begins (P398).
A049 At serial I/O (SCB1 with SCI1/2), no slave is
connected or fiber-optic cable is interrupted or
No slave slaves are without voltage.
not Compact PLUS
A050 At ser. I/O the slaves required according to a
parameterized configuration are not present
Slave incorrect (slave number or slave type): Analog inputs or
outputs or digital inputs or outputs have been
not Compact PLUS parameterized which are not physically
present.
A051 In a peer-to-peer connection a baud rate has
been selected which is too high or too
Peer baud rate different.
not Compact PLUS
A052 In a peer-to-peer connection, a PcD length has
been set which is too high (>5).
Peer PcD L
not Compact PLUS
A053 In a peer-to-peer connection, the pcD length of
transmitter and receiver do not match.
Peer Lng f.

A057 Occurs when a TB is logged on and present,
but parameter tasks from the PMU, SCom1 or
TB Param SCom2 have not been answered by the TB
within 6 seconds.

Counter-measure
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)
- Increase frequency at which DC braking
begins
P690 SSCI AnaIn Conf
- Check slave.
- Check cable.
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.
