Step 6 - Faults and warning codes
Under this menu, you can find active faults, history faults, and fault codes.
Table 22. Active faults.
Menu Function Note
Active faults When a fault/faults appear(s), the display with the name
and fault time of the fault will be pop. Press DETAIL to see
the fault data.
The active faults submenu shows the list of faults. Select
the fault and push DETAIL to see the fault data.
The fault remains active until it is cleared with the Reset
button push for 2s) or with a reset signal from the I/O terminal
or fieldbus.
The memory of active faults can store the maximum of 10 faults in
the order of appearance.
Table 23. History faults.
Menu Function Note
History faults 10 latest faults are stored in the fault history. Select the
fault and push DETAIL to see the fault data.
The history fault will be stored until it is cleared with the
OK button (push for 5 s).
The memory of active faults can store the maximum of 10 faults in
the order of appearance.
Fault codes and descriptions
Configurable 1 = The fault type of this fault is configurable, fault type can be configured as:
0 = No action; 1 = Warning; 2 = Fault; 3= Fault, Coast.
Fault
code
Fault name/
description Fault type
Default
configuration Possible cause Remedy
1 Over current
Fault AC drive has detected too high a current (>4*IH) in the motor
cable:
• Sudden heavy load increase;
• Short circuit in motor cables;
• Unsuitable motor.
• Check loading.
• Check motor.
• Check cables and connections.
• Make identication run.
• Check ramp times.
2
Over voltage Fault The DC-link voltage has exceeded the limits dened:
• Too short a deceleration time;
• Brake chopper is disabled;
• High overvoltage spikes in supply;
• Start/stop sequence too fast.
• Make deceleration time longer.
• Use brake chopper or brake resistor
(available as options).
• Activate overvoltage controller.
• Check input voltage.
3
Earth fault Fault Congurable Current measurement has detected that the sum of motor phase
current is not zero:
• Insulation failure in cables or motor.
• Check motor cables and motor.
9
Under voltage Fault Congurable DC link voltage is under the voltage limits dened:
• Most probable cause: Too low a supply voltage;
• AC drive internal fault;
• Defect input fuse;
• External charge switch not closed.
Note: This fault is activated only if the drive is in the Run state.
• In case of temporary supply voltage
break reset the fault and restart the
AC drive. Check the supply voltage. If
it is adequate, an internal failure has
occurred. Contact the distributor near
you.
10 Input phase
superv
No action Congurable Input line phase is missing. • Check supply voltage, fuses, and cable.
11 Output phase
superv
Fault Congurable Current measurement has detected that there is no current in
one motor phase.
Check motor cable and motor.
13 Drive under temp Warning Congurable Too low temperature measured in power.
Unit’s heat sink or board. Heat sink temperature is under -10°C.
14 Drive over temp Fault Too high temperature measured in power.
Unit’s heat sink or board. Heat sink temperature is over 90°C.
• Check the correct amount and ow of
cooling air.
• Check the heat sink for dust.
• Check the ambient temperature.
• Make sure that the switching frequency
is not too high in relation to ambient
temperature and motor load.
15 Motor stalled No action Congurable Motor is stalled. Check motor and load.
