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.
