Fault detection codes that are cleared as soon as their cause disappears
De te cte d Fault Nam e Probable cause Re m e dy
CFF [Incorrect config.] •
Option card changed or removed.
•
Control block replaced by a control block
configured on a drive w ith 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
81 ).
CFI
[Invalid config.] •
Invalid configuration.
The configuration loaded in the drive via
the bus or communication netw ork is
inconsistent.
•
Check the configuration loaded previously.
•
Load a compatible configuration.
CFI2
CSF [Ch. Sw . fault] •
Sw itch to not valid channels .
•
Check the function parameters.
dLF [Dynam ic 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 269 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
[Pairin g pass w ord] (PPI) if the card was changed
deliberately.
PHF [Input phase los s] •
Drive incorrectly supplied or a fuse
blow n.
•
One phase missing.
•
3-phase ER24 used on a single-phase
supply mains.
•
Unbalanced load.
This protection only operates w ith the drive
on load.
•
Check the pow er connection and the fuses.
•
Use a 3-phase supply mains.
•
Disable the detected fault by [Input phas e loss ] (IPL) =
[No]
(nO) page 86 .
USF [Unde rvoltage] •
Supply mains too low .
• Transient voltage dip.
•
Check the voltage and the parameters of
[UNDERV OLTA G E M GT]
(USb-) , page 259 .
Option card changed or removed
When an option card is rem oved or replaced by another, the drive locks in [Incorrect config.] (CFF) fault
m ode on power-up. If the card has been deliberately changed or rem oved, the detected fault can be cleared
by pres s ing the ENT key twice, which caus es the factory s ettings to be res tored (s ee page
81 ) for the
param eter groups affected by the card. Thes e are as follows :
Card replaced by a card of the same type
•
Com m unication cards : only the param eters that are s pecific to com m unication 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 m ode on power-up. If the control block has been deliberately changed, the
detected fault can be cleared by pres s ing the ENT key twice, which causes all the factory settings to be
restored.
