304 Fault tracing
0030
EXTERNAL Fault in external device.
(This information is
configured through one of
the programmable digital
inputs.) Check external devices for faults.
Check the setting of parameter
46.01 EXTERNAL FAULT.
0031 SAFE TORQUE
OFF
Programmable
fault:
46.05 STO
DIAGNOSTIC
Safe torque off function is
active, ie, safety circuit
signal(s) connected to
connector X6 is lost
• during the drive start or
drive run
or
• while the drive is
stopped and parameter
46.05 STO
DIAGNOSTIC setting is
Fault .
Check safety circuit connections.
For more information, see the
appropriate drive
Hardware
manual .
0032
OVERSPEED Motor is turning faster than
the 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 ABS
MAX SPEED.
Check the adequacy of the motor
braking torque.
Check the applicability of torque
control.
Check the need for a brake
chopper and resistor(s).
0033 BRAKE START
TORQUE
Programmable
fault:
35.08 BRAKE
FAULT FUNC
Mechanical brake fault.
The fault is activated if the
required motor starting
torque, 35.07 BRAKE
OPEN TORQ, is not
achieved. Check the brake open torque
setting, parameter 35.07.
Check drive torque and current
limits. See parameter group
20
LIMITS on page 233 .
0034
BRAKE NOT
CLOSED MON1
Programmable
fault:
35.08 BRAKE
FAULT FUNC
Mechanical brake control
fault. The fault is activated
if brake monitoring is not
as expected during brake
closing. Check the mechanical brake
connection.
Check mechanical brake settings,
parameters
35.01 … 35.08 .
To determine whether the problem
is with the monitoring signal or
brake: Check if the brake is closed
or open.
