Fault code Fault name Possible cause Correcting actions
9 Under voltage The DC-link voltage has gone below the internal
safety limit:
• most probable cause: supply voltage is too low
• frequency converter internal fault
• power outages In case of temporary supply voltage break reset the
fault and restart the frequency converter.
Check the supply voltage. If it is adequate, an internal
failure has occurred.
Contact the distributor near to you.
10 Input phase fault Input phase is missing Check supply voltage, fuses and cable.
11 Output phase fault Current measurement has detected that there is no
current in one motor phase. Check motor cable and motor.
13 Frequency converter
under temperature Heat sink temperature is under 14 °F (–10 °C) Check the ambient temperature.
14 Frequency converter over
temperature Heat sink is overheated. Check that the cooling air flow is not blocked.
Check the ambient temperature.
Clean the heatsink dust.
Make sure that the switching frequency is not too high
in relation to ambient temperature and motor load.
15 Motor stalled Motor stall protection has tripped. Check that the motor is able to rotate freely.
16 Motor over temperature Motor overheating has been detected by frequency
converter motor temperature model.
Motor is overloaded. Decrease the motor load.
If no motor overload exists, check the temperature
model parameters.
17 Motor underload Motor underload protection has tripped. Check motor and load, , as well as the low load
detection parameters (P11.14 - P11.16).
E.g. for broken belts or dry pumps.
22 EEPROM checksum fault Parameter save fault
• faulty operation
• component failure
