Failures not automatically resettable
The cause of the failure should be eliminated before resetting by turning off, and then the converter may be powered up
again.
The failures CrF,SOF,tnF,bLF and OPF are remotely resettable from the logic input (parameter rSF of the menuFLt).
Failure
bLF: brake logic failure
CrF: load circuit of capacitors
EEF: EEPROM failure
InF: internal failure
OCF: overcurrent
SCF: short circuit of motor
SOF: over speed
tnF: self-adjustment error

Probable Cause
Brake release current not reached.
Brake closing frequency level bEn =
nO (not adjusted) when the brake
logic lLC is configured.
Control failure on load relay or load
resistance damaged
Internal memory failure.
Internal failure.
Parameters of SEt- and drC- menus
not correct.
Inertia or load too high.
Mechanical block.
Short circuit or grounding at
converter's output.
High fault current going to ground at
converter's output in the case of
various motors in parallel.
Instability or traction load too high.
Special motor or power motor not
adjusted to converter.
Motor not connected to converter.

Solution
Check the converter/motor
connection.
Check the motor's windings.
Check the Ibr adjustment on the
FUn menu. Make the bEn recommended
adjustments.
Contact Technical Assistance.
Check the environment
(electromagnetic compatibility)
Contact Technical Assistance.
Check the environment
(electromagnetic compatibility)
Contact Technical Assistance.
Check SEt- and drC parameters.
Check size of motor/converter/load.
Check state of mechanics.
Check converter's connection
cables to the motor and the motor's
insulation.
Reduce switching frequency.
Add inductances in series with the
motor.
Check motor's parameters, gain,
and stability.
Add a braking resistance
Check size of motor / converter /
load.
Use the L or P relation.
Check the presence of motor on
self-adjustment.
In the case of using an upstream
contactor, close it during self-
adjustment.
