Fault
code
Fault ID Fault name Possible cause How to correct the fault
11 100 Output phase
supervision
The measurement of
current tells that there is no
current in 1 motor phase.
•
a motor or motor
cables malfunction
•
filter (du/dt, sinus)
malfunction
Do a check of the motor cable and
the motor. Do a check of the du/dt
or sinus filter.
12 110 Brake chopper
supervision
(hardware fault)
There is no brake resistor.
The brake resistor is
broken. A defective brake
chopper.
Do a check of the brake resistor
and the cabling. If they are in good
condition, there is a fault in the
resistor or the chopper. Ask
instructions from the distributor
near to you.
111 Brake chopper
saturation alarm
13 120 AC drive
undertemperature
(fault)
Too low a temperature in
the heatsink of the power
unit or in the power board.
The ambient temperature is too
low for the drive. Move the drive in
a warmer position.
14 130 AC drive
overtemperature
(fault, heatsink)
Too high a temperature in
the heatsink of the power
unit or in the power board.
The temperature limits of
the heatsink are different in
all the frames.
Do a check of the actual amount
and flow of cooling air. Examine
the heatsink for dust. Do a check of
the ambient temperature. Make
sure that the switching frequency
is not too high in relation to the
ambient temperature and the
motor load. Do a check of the
cooling fan.
131 AC drive
overtemperature
(alarm, heatsink)
132 AC drive
overtemperature
(fault, board)
133 AC drive
overtemperature
(alarm, board)
15 140 Motor stall The motor stalled. Do a check of the motor and the
load.
16 150 Motor
overtemperature
There is too heavy a load on
the motor.
Decrease the motor load. If there is
no motor overload, do a check of
the motor thermal protection
parameters (parameter group 3.9
Protections).
17 160 Motor underload There is not a sufficient load
on the motor.
Do a check of the load. Do a check
of the parameters. Do a check of
the du/dt and sinus filters.
