8992
DC link/output
stage overcurrent
•
The motor is defective, e.g.
winding overloaded, short
circuit between winding
and housing, output stage
defective.
•
Contact SEW-EURODRIVE
Service.
15
12832
DC link under-
voltage
•
The 48 V voltage supply
has failed or does not have
sufficient capacity, e.g. dur-
ing acceleration.
•
Ensure DC 48 V voltage supply.
•
Check if there is a link between
failure and the acceleration pro-
cess.
16
12816
DC link over-
voltage
•
48 V voltage supply too
high (> DC 70 V).
•
Reduce 48 V voltage supply.
17
29573
HALL track signal
error
•
Internal fault
•
Contact SEW-EURODRIVE
Service.
18
29574
PWM encoder
fault
•
Internal fault
•
Contact SEW-EURODRIVE
Service.
19
8978
I²t error motor (I²t
at 100%).
I²t monitoring has
tripped.
•
Incorrect nominal current
setting
•
Check and correct the nominal
motor current setting.
20
8977
I²t error controller
(I²t at 100%).
I²t monitoring has
tripped.
•
Incorrect nominal current
setting
•
Check and correct the nominal
motor current setting.
21
29575
PWM encoder
initialization error
•
Internal fault
•
PWM frequency could not
be correctly determined.
•
Contact SEW-EURODRIVE
Service.

STO – Driver
supply plausibility
error:
Feedback ≠
driver supply
•
Internal fault
•
Contact SEW-EURODRIVE
Service.

STO – Plausibility
STO 1 & 2 (STO
1 ≠ STO 2)
•
The STO plausibility check
signals an error: Control in-
puts STO 1 & STO 2 are
not activated at the same
time.
•
Contact SEW-EURODRIVE
Service.
26
9088
I²t at 80%
•
The load threshold of 80%
is reached.
•
Remove motor blockage.
