The electronic, thermal inverter protection reports that
the AFD is about to cut out because of an over-load
(too high current for too long). The counter for
electronic, thermal inverter protection gives a warning
at 98% and trips at 100%, while giving an alarm. The
AFD cannot be reset until the counter is below 90%.
The fault is that the AFD is overloaded by
more than 100% for too long.
WARNING/ALARM 10
Motor overtemperature (MOTOR TIME)
According to the electronic thermal protection (ETR),
the motor is too hot. Parameter 117
Motor thermal
protection
allows a choice of whether the AFD is to
give a warning or an alarm when the
Motor thermal
projection
reaches 100%. The fault is that the motor is
overloaded by more than 100% of the preset, rated
motor current for too long. Check that the motor
parameters 102-106 have been set correctly.
WARNING/ALARM 11
Motor thermistor (MOTOR THERMISTOR)
The thermistor or the thermistor connection has
been disconnected. Parameter 117
Motor thermal
protection
allows a choice of whether the AFD is to give
a warning or an alarm. Check that the thermistor has
been correctly connected between terminal 53 or 54
(analog voltage input) and terminal 50 (+ 10 V supply).
WARNING/ALARM 12
Current limit (CURRENT LIMIT)
The current is higher than the value in parameter 215
Current limit I
LIM
and the AFD trips after the time set in
parameter 412
Trip delay overcurrent, I
LIM
has passed.
WARNING/ALARM 13
Overcurrent (OVER CURRENT)
The inverter peak current limit (approx. 200% of the
rated current) has been exceeded. The warning
will last approx. 1-2 seconds, following which the
AFD will trip and give off an alarm.
Turn off the AFD and check whether the motor
shaft can be turned and whether the motor
size matches the AFD.
ALARM: 14
Ground fault (GROUND FAULT)(GROUND FAULT)
There is a discharge from the output phases to
ground, either in the cable between the AFD and
the motor or in the motor itself.
Turn off the AFD and remove the ground fault.
ALARM: 15
Switch mode fault (SWITCH MODE FAULT)
Fault in the switch mode power supply
(internal ± 15 V supply).
Contact your Danfoss supplier.
ALARM: 16
Short-circuiting (CURR. SHORT CIRCUIT)
There is short-circuiting on the motor terminals
or in the motor itself.
Cut off the line supply to the AFD and
remove the short-circuit.
WARNING/ALARM 17
Serial communication timeout (STD
BUSTIMEOUT)
There is no serial communication with the AFD.
This warning will only be enabled if parameter
556
Bus time interval function
has been set
to a value different from OFF.
If parameter 556
Bus time interval function
has
been set to Stop and trip [5], the AFD will first
give off an alarm, then ramp down and finally trip
while giving off an alarm. It is possible to increase
parameter 555
Bus time interval.
WARNING/ALARM 18
HPFB bus timeout (HPFB TIMEOUT)
There is no serial communication with the
communication option card of the AFD.
The warning will only be enabled if parameter
804
Bus time interval function
has been set to
anything but OFF. If parameter 804
Bus time interval
function
has been set to
Stop and trip,
the AFD
will first give off an alarm, then ramp down and
finally trip while giving off an alarm.
Parameter 803
Bus time interval
could
possibly be increased.
WARNING 19
Fault in the EEprom on the power card
(EE ERROR POWER)
There is a fault on the power card EEPROM. The
AFD will continue to function, but is likely to fail at the
next power-up. Contact your Danfoss supplier.
WARNING 20
Fault in the EEprom on the control card
(EE ERROR CONTROL)
