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
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
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
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
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.
In a peer-to-peer connection, the pcD length of
transmitter and receiver do not match.
Adjust the word length for transmitter and
receiver
P703 SCom/SCB PcD #
A057
TB Param
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
Alarm 1
Function blocks
An active signal is present at binector U065
(1).
Check cause of alarm (see FD 710)
A062
Alarm 2
Function blocks
An active signal is present at binector U066
(1).
Check cause of alarm (see FD 710)
A063
Alarm 3
Function blocks
An active signal is present at binector U067
(1).
Check cause of alarm (see FD 710)
A064
Alarm 4
Function blocks
An active signal is present at binector U068
(1).
Check cause of alarm (see FD 710)
A065
Auto restart active
The auto restart option (P373) restarts the
drive. A possibly parameterized power-up
delay time (P374) expires if flying restart is not
selected. During pre-charging of the DC link,
there is no time monitoring i.e. with an external
electronics power supply, it is also switched-in
again.
Caution!
Personnel could be in danger when the drive
automatically restarts. Check whether the auto
restart function is really required!
A066
fsyn > fmax
The measured target frequency of the external
converter (or supply) is greater than the
parameterized maximum frequency of the
synchronizing converter.
Check:
- P452 n/f(max, FWD Spd)/ P453 n/f(max,REV
Spd) are correct and
- correct motor data set P578 Src MotDSet
Bit0 are selected
A067
fsyn < fmin
The measured target frequency of the external
converter (or supply) is less than the minimum
frequency required for synchronizing.
Check:
- r533 Sync Target Freq
- Synchronizing cable.
A068
fsyn<>fsoll
The setpoint frequency of the synchronizing
converter deviates too significantly from the
measured target frequency of the external
converter (or supply). The permissible
deviation can be set in P529.
Adjust total setpoint (main and additional
setpoints) to the target frequency displayed in
visualization parameter r533.
