Occurs when a TB is logged on and
present, but parameter tasks from
the PMU, SCom1 or SCom2 are not
answered by the TB within 6
seconds.
Replace TB configuration (software).

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!

1
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
r957
2
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
• Synchronising cable
A068 r957
3
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.

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 has been correctly
set.
