Fault code Possible cause Checking
F 7
Saturation trip
Very high overload or defective component
Reset: switch power off and restart after the lamps of
keypad are off.
Check:
−
motor and motor cable insulation
−
measure main circuit diodes and IGBT transistors
If the fault comes again, change the D2V.
F8
System fault
System fault due to component failure or
faulty operation.
Reset: switch power off and restart after the lamps of
keypad are off.
Check:
−
read fault extension code and contact authorized
service
If the fault comes again, change the D2V.
F 9
Undervoltage
DC-bus voltage has dropped below 333Vdc
−
mains supply voltage interrupted
−
inverter fault can also cause an
undervoltage trip
− external fault during run may cause an
undervoltage trip
In case of temporary supply voltage break, reset the
fault and start again. Check mains input.
−
if mains supply is correct, an internal failure has
occurred
−
contact authorized service
F 10
Input line
supervision
One input line phase is missing or
supply voltage parameter is wrong
Check:
− supply voltage
−
mains connection
F 11
Output phase
supervision
Current supervision has sensed that one of
the motor phases has no current
Check:
−
motor cable connections
−
measure motor phase currents and compare to
display value
F 12
Braking chopper
supervision
Braking chopper or braking resistor circuit
has failed. Fault appears if
−
braking resistor is broken
−
braking chopper is broken
−
braking resistor is not installed
Reset: switch power off and restart after the lamps of
keypad are off.
Check:
−
braking resistor and cable resistance and
insulation resistance
−
measure braking transistor IGBT and free
wheeling diodes
− if resistor is OK, then the chopper is broken
−
contact authorized service
F 13
Inverter
undertemperature
Temperature of heat sink is below
acceptable operating level -10°C (14°F)
Check
−
ambient temperature
− cubicle heating
−
inverter cooling fan activation (continuous /
temperature limit)
F 14
Inverter
overtemperature
Temperature of heat sink is over acceptable
operating level
+90°C (194°F).
Overtemperature warning is issued when the
heat sink temperature exceeds +85°C
(185°F)
Check:
−
ambient temperature
− inverter cooling fan operation
−
cooling air flow through heat sink
− heat sink is not dusty
F16
Motor
overtemperature
Mathematical motor temperature model has
detected motor overheating. Motor is
overloaded.
Check:
−
motor load
− if no overload exists, then check motor
temperature model parameters
F 22
F 23
EEPROM
checksum fault
Parameter save error
− interference fault
−
component failure (control unit)
After power off the inverter will automatically load
factory default parameter settings. XT Drive does not
work properly nor enable running after this fault.
Check:
−
all parameter settings
− +24V voltage output loading
If the fault comes again, contact authorized service.
