Cause
Overvoltage detected in
AI. AI is changed to
voltage mode from mA
mode. AI will return auto-
matically back to mA
mode when the AI signal
level is within acceptable
limits.
I/O module configuration
not supported or illegal.
S1/S2 DIP switch position
on BIO-01 has changed
after power up.
S1/S2 DIP switch posi-
tions are such that DO1
would be in both S1 and
S2 pins. This is not a sup-
ported combination.
Mechanical brake control
fault. Activated e.g., if
brake acknowledgment is
not as expected during
brake closing.
Open conditions of mech-
anical brake cannot be
fulfilled.
Excitation current feed-
back low or missing
Motor is operating in stall
region.
Diagnostics 163
What to do
Check AI signal levels.
Check the auxiliary code. See ac-
tions for
each code below.
Reboot control unit either by cyc-
ling the power or through paramet-
er 96.08 Control board boot to ac-
tivate new DIP switch position.
Change S1/S2 DIP switch positions
to a supported combination, see
parameter 05.99 BIO-01 DIP switch
status.
Check mechanical brake connec-
tion. Check mechanical brake set-
tings in parameter group 44 Mech-
anical brake control.
Check that the acknowledgment
signal matches the actual status of
the brake.
Check mechanical brake settings in
parameter group 44 Mechanical
brake control.
Check that the acknowledgment
signal (if used) matches the actual
status of the brake.
Contact your local ABB representat-
ive.
Check motor load, drive ratings and
fault function parameters.
