Number / Alarm Cause
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.
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
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.
A052 In a peer-to-peer connection, a PcD length has
been set which is too high (>5).
Peer PcD L
A053 In a peer-to-peer connection, the pcD length of
transmitter and receiver do not match.

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.
A061 An active signal is present at binector U065
(1).

A065 The auto restart option (P373) restarts the
drive. A possibly parameterized power-up
Auto restart active 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.
A066 The measured target frequency of the external
converter (or supply) is greater than the
fsyn > fmax parameterized maximum frequency of the
synchronizing converter.
A067 The measured target frequency of the external
converter (or supply) is less than the minimum
fsyn < fmin frequency required for synchronizing.
A068 The setpoint frequency of the synchronizing
converter deviates too significantly from the
fsyn<>fsoll measured target frequency of the external
converter (or supply). The permissible
deviation can be set in P529.

Caution!
Personnel could be in danger when the drive
automatically restarts. Check whether the auto
restart function is really required!
Check:
- P452 n/f(max, FWD Spd)/ P453 n/f(max,REV
Spd) are correct and
- correct motor data set P578 Src MotDSet

Adjust total setpoint (main and additional
setpoints) to the target frequency displayed in
