Fault detection codes that are cleared as soon as their cause disappears
Option card changed or removed
When an option card is removed or replaced by another, the drive locks in [Incorrect config.] (CFF) fault
mode on power-up. If the card has been deliberately changed or removed, the detected fault can be cleared
by pressing the ENT key twice, which causes the factory settings to be restored (see page 69
) for the
parameter groups affected by the card. These are as follows:
Card replaced by a card of the same type
• Communication cards: only the parameters that are specific to communication cards
Control block changed
When a control block is replaced by a control block configured on a drive with a different rating, the drive locks
in [Incorrect config.] (CFF) fault mode on power-up. If the control block has been deliberately changed, the
detected fault can be cleared by pressing the ENT key twice, which causes all the factory settings to be
restored.
Detected Fault Name Probable cause Remedy
CFF
[Incorrect config.]
• Option card changed or removed.
• Control block replaced by a control block
configured on a drive with a different
rating.
• The current configuration is inconsistent.
• 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 block being changed
deliberately, see the remarks below.
• Return to factory settings or retrieve the backup
configuration, if it is valid (see page 69
).
CFI
[Invalid config.]
• Invalid configuration.
The configuration loaded in the drive via
the bus or communication network is
inconsistent.
• Check the configuration loaded previously.
• Load a compatible configuration.
CFI2
CSF
[Ch. Sw. fault]
• Switch to not valid channels. • Check the function parameters.
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.
FbE
[FB fault]
• Function blocks error. • See [FB Fault] (FbFt) for more details.
HCF
[Cards pairing]
• The [CARDS PAIRING] (PPI-)
function page 250
has been configured
and a drive card has been changed.
• In the event of a card error, reinsert the original card.
• Confirm the configuration by entering the
[Pairing password] (PPI) if the card was changed
deliberately.
PHF
[Input phase loss]
• Drive incorrectly supplied or a fuse
blown.
• One phase missing.
• 3-phase ATV32 used on a single-phase
line supply.
• Unbalanced load.
This protection only operates with the drive
on load.
• Check the power connection and the fuses.
• Use a 3-phase line supply.
• Disable the detected fault by [Input phase loss] (IPL) =
[No] (nO) page 74
.
USF
[Undervoltage]
• Line supply too low.
• Transient voltage dip.
• Check the voltage and the parameters of
[UNDERVOLTAGE MGT] (USb-), page 241
.
