Danfoss AKD 5001 Manual page 107

If no 24 V power supply is connected, the
frequency converter will trip after a given time
that depends on the unit.
Furthermore, the voltage will be stated in the display.
Check whether the supply voltage matches the
frequency converter, see technical data.
WARNING/ALARM 9
Inverter overload (INVERTER TIME):
The electronic, thermal inverter protection reports that
the frequency converter is about to cut out because
of an overload (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 frequency converter cannot
be reset until the counter is below 90%.
The fault is that the frequency converter 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 128 allows a choice of
whether the frequency converter is to give a warning
or an alarm when the counter reaches 100%. The
fault is that the motor is overloaded by more than
100% for too long. Check that 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 128 allows a choice of
whether the frequency converter is to give a warning or
an alarm. Check that the thermistor has been correctly
connected between terminal 53 or 54 (analogue
voltage input) and terminal 50 (+ 10 Volts supply).
WARNING/ALARM 12
Torque limit (TORQUE LIMIT):
The torque is higher than the value in parameter 221
(in motor operation) or the torque is higher than the
value in parameter 222 (in regenerative operation).
WARNING/ALARM 13
Overcurrent (OVERCURRENT):
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
frequency converter will trip, while giving an alarm.
Turn off the frequency converter and check whether
the motor shaft can be turned and whether the motor
size matches the frequency converter.

If extended mechanical brake control is selected,
trip can be reset externally.
