2.10.4 Fault that can be eliminated as soon as the cause is removed.
The fault can also be decentrally locked and deleted via a logic input.
(Parameter
[Fault inhibit assign.]
(InH) ).
Error Name Probable cause Error correction
CFF [Incorrect config] • Option card changed or removed
• Control card replaced by a control card
configured on a inverter with a different
rating
• The current configuration is inconsis-
tent.
• Check that there are no card errors.
• In the event of the option card being changed/removed
deliberately, see the remarks below
•
Check that there are no card errors.
•
In the event of the control card being changed deliber-
ately, see the remarks below
• Restore the factory settings or the backup configura-
tion (if valid) ( see "Factory setting parameters (FCS1 -
SCS1)" on page 315 ).
CFI [Config invalid] • Invalid configuration. The configuration
loaded in the frequency inverter via the
bus or communication network is incon-
sistent.
• Check the last loaded configuration
• Load a compatible configuration.
dLF [Dynamic load fault] • Abnormal load variation • Check that the load is not blocked by an obstacle
• Removal of a run command causes a reset
HCF [CARDS PAIRING]
•
The function
[CARDS PAIRING] (PPI-) ( see "Cards
pairing" on page 306 ) has been config-
ured and a inverter card changed.
•
In the event of a card error, reinsert the original card
•
Configuration by entering
[Merge code] (PPI) must be confirmed if the card has
been intentionally switched
PHF [Line phase error] • Inverter incorrectly supplied or a fuse
blown
• Failure of one phase
• 3-phase ACOPOSinverter P84 used on
a single-phase line supply
• Unbalanced load
Protection function is only effective under load
• Check the power connection and the fuses.
•
Use a 3-phase line supply.
•
Disable the fault by [Line phase loss] (IPL) = [No] (nO) .
USF [Undervoltage] • Line supply too low
• Transient voltage dip
• The voltage and the parameters of
[UNDERVOLTAGE MGT.] (USb-) must be checked.
2.10.5 Change or removal of the option card
If the option card is deleted or replaced by another, the inverter locks in fault mode [Incorrect config.] (CFF) when
switching on. If the card has been replaced or removed intentionally select "Yes" and the error can be deleted.
Hold the ENT key for two seconds.
This results in the
restoration of all factory settings ( see "Factory setting parameters (FCS1 - SCS1)" on page
315 ) for the card-specific parameter groups.
These are:
Card replaced by a card of the same type
• Encoder cards: [config inverter] (drM)
• Communication cards: Only the parameters that are specific to communication cards
Remove the card (or replace it with a card of a different type):
•
Encoder cards:
[config inverter]
(drM)
• Communication card: [config inverter] (drM) and communication card-specific parameters
2.10.6 Changing the control card
If a control card is replaced by a control card that has been configured in another type of inverter, the inverter locks
in fault mode [Incorrect config.] (CFF) when switching on. If the card was intentionally replaced, the fault can be
deleted by pressing twice on the ENT key, which results in the restoration of all factory settings .
