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. D2H/D2C does
not work properly nor enable driving after this
fault.
Check:
all parameter settings
+24V voltage output loading
If the fault comes again, contact authorized
service.
