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.
B793 FSE Ch1 diag
event Encoder failure. Check the encoder. In case of an
encoder event
A7E1 Encoder
warning exists in the drive event log,
fix the encoder fault. FSO module
reset is also needed if the FSO
module is in the Fail safe mode.
B794 FSE Ch2 diag
event Encoder failure. Check the encoder. In case of an
encoder event
A7E1 Encoder
warning exists in the drive event log,
fix the encoder fault. FSO module
reset is also needed if the FSO
module is in the Fail safe mode.
BA90 FSO stop
completed
FSO module has
completed the STO, SS1
or SSE function. -
1)
BA91 FSO safe speed
limit
FSO module detected an
SLS or SMS speed trip
limit violation. Check the separate code related to
SLS and SMS functions.
See section
User-selectable events
for limit hits and special events on
page 501 .
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 or
FSOGEN.52 Zero speed with
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 ).
