Fault tracing 271
0030 EXTERNAL
(0x9000) Fault in external device. (This
information is configured
through one of programmable
digital inputs.) Check external devices for faults.
Check parameter
30.01 External fault
setting.
0031 SAFE TORQUE OFF
(0xFF7A)
Programmable fault:
Programmable fault:
30.07 Sto diagnostic
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
30.07
Sto diagnostic is set to Fault .
Check safety circuit connections. For
more information, see appropriate drive
hardware manual.
0032 OVERSPEED
(0x7310) 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. Check minimum/maximum speed
settings, parameters
20.01 Maximum
speed and 20.02 Minimum speed .
Check adequacy of motor braking torque.
Check applicability of torque control.
Check need for brake chopper and
resistor(s).
0033 BRAKE START
TORQUE
(0x7185)
Programmable fault:
42.12 Brake fault func
Mechanical brake fault. Fault is
activated if required motor
starting torque (
42.08 Brake
open torq ) is not achieved.
Check brake open torque setting,
parameter
42.08 .
Check drive torque and current limits.
See parameter group
20 Limits .
0034 BRAKE NOT
CLOSED
(0x7186)
Programmable fault:
42.12 Brake fault func
Mechanical brake control fault.
Activated e.g. if brake
acknowledgement is not as
expected during brake closing. Check mechanical brake connection.
Check mechanical brake settings in
parameter group
42 Mech brake ctrl .
To determine whether problem is with
acknowledgement signal or brake, check
if brake is closed or open.
0035 BRAKE NOT OPEN
(0x7187)
Programmable fault:
42.12 Brake fault func
Mechanical brake control fault.
Activated e.g. if brake
acknowledgement is not as
expected during brake
opening.
Check mechanical brake connection.
Check mechanical brake settings in
parameter group
42 Mech brake ctrl .
To determine whether problem is with
acknowledgement signal or brake, check
if brake is closed or open.
0036 LOCAL CTRL LOSS
(0x5300)
Programmable fault:
30.03 Local ctrl loss
Control panel or PC tool
selected as active control
location for drive has ceased
communicating. Check PC tool or control panel
connection.
Check control panel connector.
Replace control panel in mounting
platform.
0037 NVMEM
CORRUPTED
(0x6320) Drive internal fault
Note: This fault cannot be
reset.
Contact your local ABB representative.
0038 OPTIONCOMM LOSS
(0x7000) Communication between drive
and option module (FEN-xx
and/or FIO-xx) is lost. 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.
