Fault tracing 357
AAB4 FSO speed sync
fail
FSO module detected a
difference between the
two monitored motor
speed values (
200.01
FSO speed ch1 and
200.02 FSO speed ch2 ).
Restart the drive and FSO module.
2)
AAB5 FSO varSLS hit FSO module detected a
Variable SLS speed limit
violation. Make sure that varSLS trip limits are
defined properly.
Check that transient mute time values
are defined properly (
FSOGEN.31 ).
2)
AAB6 FSO safebus
passivation
FSO module was
passivated due to
communication problems. Check the fieldbus connection and
fieldbus controller for passivation
cause.
5)
Events
B790 FSO general
event FSO module generated
an event other than a fault
or a warning. See the tips in the Drive Composer
PC tool. 3)
B792 FSO undefined
event FSO new version,
undefined event in the
drive event system. Contact your local ABB
representative.
BA90 FSO stop
completed
FSO module has
completed the STO, SS1
or SSE function. - 1)
BA91 FSO safe speed
limit
Motor actual speed
exceeded an SLS1...4 or
SMS limit of the FSO
module. Check the drive.
2) 3)
BA92 FSO out of eme
ramp
Motor speed was not
inside the ramp window
during the SSE function. Make sure that the drive can
decelerate the load using the ramp
time (
200.102 SAR0 ramp time to
zero ).
2)
BA93 FSO ramp
coasted
Drive coasted the motor
to stop instead of using
the ramp. Check that the FSO module zero
speed limit for the deceleration ramp
is not excessive (
FSOGEN.51 Zero
speed without encoder ).
2)
BA94 FSO out of safe
ramp
Motor speed was not
inside the ramp window
during the SS1 function. Make sure that the drive can
decelerate the load using the ramp
time (
200.112 SAR1 ramp time to
zero ).
2)
BA99 FSO passivated FSO module was
passivated due to safety
fieldbus problems. Check the fieldbus connection and
fieldbus controller for passivation
cause.
5)
BAA1 FSO STO request FSO module received an
external STO request.
