Fault code Fault Possible cause Correcting measures
10 Input line
supervision Input line phase is missing. Check supply voltage and cable.
11 Output phase
supervision Current measurement has detected
that there is no current in one motor
phase. Check motor cable and motor.
12 Brake chopper
supervision • no brake resistor installed
• brake resistor is broken
• brake chopper failure
Check brake resistor. If the resistor is
ok, the chopper is faulty. Contact the
distributor near to you.
13 Frequency
converter under
temperature Heatsink temperature is under -10
°C/-50 °F
14 Frequency
converter over
temperature Heatsink temperature is over 90 °C/
194 °F. Over temperature warning is
issued when the heatsink
temperature exceeds 85 °C/185 °F. Check the correct amount and flow of
cooling air. Check the heatsink 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 Motor stall protection has tripped. Check motor.
16 Motor
overtemperature 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. Decrease the motor load. If no motor
overload exists, check the
temperature model parameters.

23 EEPROM
checksum fault Parameter save fault
• faulty operation
• component failure
24 Changed data
warning Changes may have occurred in the
different counter data due to mains
interruption No special actions required. Take a
critical attitude to the counter data.
25 Microprocessor
watchdog fault
•
faulty operation
• component failure
Reset the fault and restart. Should the
fault re-occur, contact the distributor
near to you.
32 Fan cooling Cooling fan of the frequency
converter does not start, when ON
command is given Contact the distributor near to you.
36 Control unit NXS Control Unit can not control NXP
Power Unit and vice versa Change control unit
37 Device change Option board changed. Different
power rating of drive. Reset
38 Device added Option board added. Drive of different
power rating added. Reset
39 Device removed Option board removed. Drive
removed. Reset
40 Device unknown Unknown option board or drive.
41 IGBT temperature IGBT Inverter Bridge over
temperature protection has detected
too high a short term overload current
Check loading. Check motor size.
