Error Name Probable cause Error correction
ILF [Internal serial link] • Communication fault between the com-
munication card and inverter
• Check the environment (electromagnetic compatibility).
• Check the connections.
• Check that the allowed maximum of 2 option cards on
the inverter is not exceeded.
• Replace the option card.
• Examine and repair the inverter
InF1 [Wrong FU value] • The power card is different from the
card stored
• Check the reference of the power card.
InF2 [Power incompatible]
•
The power card is incompatible with the
control card.
•
Check the reference of the power card and its compat-
ibility.
InF3 [int communication] • Communication fault between the inter-
nal cards
• Check the internal connections.
• Examine and repair the inverter
InF4 [Internal-mftg zone] • Internal data inconsistent • Have the inverter re-calibrated (through the B&R Tech
Support)
InF6 [Int. option] • The option installed in the inverter is not
recognized
• Check the reference and the compatibility of the option.
InF7 [Int. init. hardw] • The inverter is not yet completely initial-
ized.
• Switch the inverter off and reset it.
InF8 [Internal power supply volt-
age]
• Fault in the control power supply • Check the control power supply.
InF9 [Internal- I measure]
•
The current measurements are not cor-
rect.
•
Run the diagnostic tests via the menu
[DIAGNOSIS] .
• Examine and repair the inverter
InFA [Internal Power supply volt-
age supply]
• The input stage is not operating correct-
ly
• Perform diagnostic tests via the menu [DIAGNOSIS] .
• Check/repair the inverter.
InFb [Internal PTC sensor] • The inverter temperature sensor is not
operating correctly
•
The brake unit temperature sensor is
not operating correctly
• Replace the temperature sensor of the inverter
• Examine and repair the inverter
• Replace the temperature sensor of the brake unit
• Examine and repair the brake unit
InFC [Internal Time measure]
•
Fault on the electronic timer
•
Examine and repair the inverter
InFE [Internal - CPU]
•
Internal microprocessor fault
•
Switch the inverter off and reset it. Examine and repair
the inverter.
OCF [Overcurrent] • Parameters of the menus
[SETTINGS] (Set-) and
[DRIVE DATA] (drC-) are not correct.
• Inertia or load too high
• Mechanical locking
• Check the parameters.
• Check the dimensioning of the motor/inverter/load.
• Check the state of the mechanism.
PrF [Power removal] • Fault of the safety function "power re-
moval" of the inverter
• Examine and repair the inverter
SCF1
[Motor short circuit]
SCF2 [Imp short circuit]
SCF3 [Ground short circuit]
•
Short-circuit or grounding at the inverter
output
• Significant earth leakage current at the
frequency inverter output if several mo-
tors are connected in parallel
•
Check the connection cables from the inverter to the mo-
tor and the insulation of the motor.
• Run the diagnostic tests via the menu
[DIAGNOSIS] .
•
Reduce the frequency.
•
Connect motor throttles in series.
•
Check speed control and brake adjustment.
•
Increase the value of the parameter
[Time to restart] (ttr) ( see "Setting parameters (bEt -
ttL)" on page 148 ).
SOF [Overspeed]
•
Instability or driving load too high
•
Check the motor, amplification and stability parameters.
•
Add a brake resistor.
•
Check the dimensioning of the motor/inverter/load.
SPF [Speed fdback loss] • Feedback signal of the encoder is miss-
ing
• There is no signal at the pulse input if
this is used for the speed measurement
• Check the wiring between the encoder and the inverter.
• Check the encoder.
• Check the wiring at the input and at the detector used.
tnF [AUTO TUNING FAULT] • Special motor or motor whose power is
not suitable for the inverter
• Motor not connected to the inverter
• Check that the motor and inverter are compatible
• Check that the motor is present during autotuning
• Connect the motor protection during the autotuning
