Cause
Fault in external device. (This
information is configured
through one of programmable
digital inputs.)
Safe Torque Off function is
active, i.e. safety circuit
signal(s) connected to
connector X6 is lost during
start or run, or while drive is
stopped and parameter
Sto diagnostic is set to Fault.
Motor is turning faster than
highest allowed speed due to
incorrectly set minimum/
maximum speed, insufficient
braking torque or changes in
load when using torque
reference.
Mechanical brake fault. Fault is
activated if required motor
starting torque (42.08 Brake
open torq) is not achieved.
Mechanical brake control
alarm. Fault is activated e.g. if
brake acknowledgement is not
as expected during brake
closing.
Mechanical brake control
alarm. Fault is activated e.g. if
brake acknowledgement is not
as expected during brake
opening.
Control panel or PC tool
selected as active control
location for drive has ceased
communicating.
Drive internal fault
Note: This fault cannot be
reset.
Communication between drive
and option module (FEN-xx
and/or FIO-xx) is lost.
What to do
Check external devices for faults.
Check parameter
setting.
Check safety circuit connections. For
more information, see appropriate drive
hardware manual.
30.07
Check minimum/maximum speed
settings, parameters
speed and 20.02 Minimum
Check adequacy of motor braking torque.
Check applicability of torque control.
Check need for brake chopper and
resistor(s).
Check brake open torque setting,
parameter 42.08.
Check drive torque and current limits.
See parameter group
Check mechanical brake connection.
Check mechanical brake settings in
parameter group
To determine whether problem is with
acknowledgement signal or brake, check
if brake is closed or open.
Check mechanical brake connection.
Check mechanical brake settings in
parameter group
To determine whether problem is with
acknowledgement signal or brake, check
if brake is closed or open.
Check PC tool or control panel
connection.
Check control panel connector.
Replace control panel in mounting
platform.
Contact your local ABB representative.
Check that option modules are properly
connected to Slot 1 and (or) Slot 2.
Check that option modules or Slot 1/2
connectors are not damaged. To
determine whether module or connector
is damaged: Test each module
individually in Slot 1 and Slot 2.
