Warning
Alarm
Trip lock
Cause
13
Overcurrent
X
X
X
Inverter peak current limit is exceeded. For J1–J6 units, if
this alarm occurs on power-up, check whether power
cables are mistakenly connected to the motor terminals.
14
Earth fault
–
X
X
Discharge from output phases to ground.
16
Short circuit
–
X
X
Short circuit in motor or on motor terminals. For J7 units,
if this alarm occurs on power-up, check whether power
cables are mistakenly connected to the motor terminals.
17
Control word timeout
X
X
–
No communication to frequency converter.
18
Start failed

25
Brake resistor short-circuited
–
X
X
Brake resistor is short-circuited, thus the brake function is
disconnected.
26
Brake overload
X
X
–
The power transmitted to the brake resistor over the last
120 s exceeds the limit. Possible corrections: Decrease
brake energy via lower speed or longer ramp time.
27
Brake IGBT/Brake chopper short-
circuited
–
X
X
Brake transistor is short-circuited, thus brake function is
disconnected.
28
Brake check
–
X
–
Brake resistor is not connected/working.
30
U phase loss
–
X
X
Motor phase U is missing. Check the phase.
31
V phase loss
–
X
X
Motor phase V is missing. Check the phase.
32
W phase loss
–
X
X
Motor phase W is missing. Check the phase.
34
Fieldbus fault
X
X
–
PROFIBUS communication issues have occurred.
35
Option fault
–
X
–
Fieldbus or option B detects internal faults.
36
Mains failure
X
X
–
This warning/alarm is only active if the supply voltage to
the frequency converter is lost and
parameter 14-10 Mains
Failure
is NOT set to
[0] No Function

Check the load connected to terminal 27 or remove
short-circuit connection.
41
Overload T29
X
–
–
Check the load connected to terminal 29 or remove
short-circuit connection.

Motor current is too low. Check the settings.
53
AMA big motor
–
X
–
The power size of the motor is too large for the AMA to
operate.
54
AMA small motor
–
X
–
The power size of the motor is too small for the AMA to
operate.
55
AMA parameter range
–
X
–
The parameter values of the motor are outside of the
acceptable range. AMA does not run.
56
AMA interrupt
