14.1 fault messages
warning 1, 10 Volts low:
The 10 v voltage from terminal 50 on the control card is below
10 v. Remove some of the load from terminal 50, as the 10 v sup-
ply is over-loaded. Max. 15 ma or minimum 590 Ω.
warning/alarm 2, Live zero error:
The signal on terminal 53 or 54 is less than 50% of the value set
in par.6–10 Terminal 53 Low Voltage, par. 6–12 Terminal 53 Low
Current, par.6–20 Terminal 54 Low Voltage, or par. 6–22 Termi-
nal 54 Low Current respectively.
warning/alarm 3, No motor:
No motor has been connected to the output of the inverter.
warning/alarm 4, Mains phase loss:
A phase is missing on the supply side, or the mains voltage im-
balance is too high. This message also appears in case of a fault
in the input rectifier on the inverter. Check the supply voltage
and supply currents to the inverter.
warning 5 , dc link voltage high:
The intermediate circuit voltage (dc) is higher than the over-
voltage limit of the control system. The inverter is still active.
warning 6, dc link voltage low:
The intermediate circuit voltage (dc) is below the under voltage
limit of the control system. The inverter is still active.
warning/alarm 7, dc over voltage:
If the intermediate circuit voltage exceeds the limit, the inverter
trips after a time.
warning/alarm 8, dc under voltage:
If the intermediate circuit voltage (dc) drops below the “voltage
warning low” limit, the inverter checks if 24 v back-up supply is
connected. If no 24 v backup supply is connected, the inverter
trips after a given time depending on the unit.
warning/alarm 9, Inverter overloaded:
The inverter 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. You cannot reset the inverter until the
counter is below 90%. The fault is that the inverter is overloaded
by more than nominal
warning/alarm 10, Motor etr over temperature:
According to the electronic thermal protection (etr), the motor
is too hot. You can choose if you want the inverter to give a
warning or an alarm when the counter reaches 100% in par. 1–90
Motor Thermal Protection. The fault is that the motor is over-
loaded by more than nominal current for too long. Check that
the motor par. 1–24 Motor Current is set correctly.
warning/alarm 11, Motor thermistor over temp:
The thermistor or the thermistor connection is disconnected.
You can choose if you want the inverter to give a warning or an
alarm in par. 1-90 Motor Thermal Protection. Check that the
thermistor is connected correctly between terminal 53 or 54
(analog voltage input) and terminal 50 (+ 10 Volts supply), or
between terminal 18 or 19 (digital input pnp only) and terminal
50. If a kty sensor is used, check for correct connection between
terminal 54 and 55.
warning/alarm 12, Torque limit:
The torque is higher than the value in par. 4–16 Torque Limit Mo-
tor Mode (in motor operation) or the torque is higher than the
value in par.4–17 Torque Limit Generator Mode (in regenerative
operation).
warning/alarm 13, Over Current:
The inverter peak current limit (approx. 200% of the rated cur-
rent) is exceeded. The warning will last approx. 8–12 sec., then
the inverter trips and issues an alarm. Turn o the inverter and
check if the motor shaft can be turned and if the motor size
matches
the inverter.
alarm 14, Earth fault:
There is a discharge from the output phases to earth, either in
the cable between the inverter and the motor or in the motor
itself. Turn o the inverter and remove the earth fault.
alarm 15, In-complete hardware:
A fitted option is not handled by the present control board
(hardware or software).
alarm 16, Short-circuit:
There is short-circuiting in the motor or on the motor terminals.
Turn o the inverter and remove the short-circuit.
warning/alarm 17, Control word timeout:
There is no communication to the inverter.The warning will only
be active when par. 8–04 Control Timeout Function is not set to
o. If par. 8–04 Control Timeout Function is set to Stop and Trip,
a warning appears and the inverter ramps down to zero speed,
while giving an alarm. par. 8–03 Control Timeout Time could
possibly be increased.
warning 22, Hoist Mech. Brake:
Report value will show what kind it is.0 = The torque ref. was not
reached before timeout1 = There was no brake feedback
before timeout.
warning 23, Internal fans:
External fans have failed due to defect hardware or fans not
mounted.
warning 24, External fan fault:
The fan warning function is an extra protection function that
checks if thefan is running / mounted. The fan warning can be
disabled in par.14–53 Fan Monitor, [0] Disabled.
