586 Fault tracing
AFE7 Follower A follower drive has tripped. Check the auxiliary code. Add 2 to the
code to find out the node address of the
faulted drive.
Correct the fault in the follower drive.
AFEA Enable start signal
missing
(Editable message text)
No enable start signal
received.
Check the setting of (and the source
selected by) parameter 20.19 Enable
start command.
AFEB Run enable missing
(Editable message text)
No run enable signal is
received.
Check setting of parameter 20.12 Run
enable 1 source. Switch signal on (e.g. in
the fieldbus Control Word) or check
wiring of selected source.
AFEC External power signal
missing
95.04 Control board supply is
set to External 24V but no
voltage is connected to the
XPOW connector of the control
unit.
Check the external 24 V DC power
supply to the control unit, or change the
setting of parameter 95.04.
AFF6 Identification run Motor ID run will occur at next
start, or is in progress.
Informative warning.
AFF7 Autophasing Autophasing will occur at next
start.
Informative warning.
B5A0 STO event
Programmable event:
31.22 STO indication
run/stop
Safe torque off function is
active, i.e. safety circuit
signal(s) connected to
connector XSTO is lost.
Check safety circuit connections. For
more information, see appropriate drive
hardware manual and description of
parameter 31.22 STO indication run/stop
(page 306).
B5A4 SW internal
diagnostics
Control unit rebooted
unexpectedly.
Informative event.
B686 Checksum mismatch
Programmable event:
96.54 Checksum action
The calculated parameter
checksum does not match any
enabled reference checksum.
See A686 Checksum mismatch (page
574).
D200 Cleaning max warning Maximum number of cleanings
in defined time frame has been
exceeded.
Check parameters 81.51Cleaning max
event to 81.53 Clean max period (page
445) for clean maximum protection
settings.
D201 U/f curve settings
invalid
U/f curve frequency points are
not defined in proper
ascending order.
Check parameters 80.11 Frequency point
1 to 80.18 Frequency point 8 (page 438).
D205 Underload Underload supervision signal
exceeded the defined
underload supervision limit.
Check parameters in group 79 Load
protection (page 429).
D207 Restart delay Restart delay is active - The
drive start command is
inhibited for the time set in
parameter 74.21 Restart delay
time.
Check parameters 74.20 Restart delay
enable and 74.21 Restart delay time.
D208 Overload Overload supervision signal
exceeded the defined overload
supervision limit.
Check parameters 79.61 Overload
recovery speed and 79.62 Overload
recovery speed time.
