Diagnostics and Troubleshooting
Fault detection codes which require a power reset after the detected fault is cleared
The caus e of the detected fault m us t be rem oved before res etting by turning off and then back on.
ASF , brF , SOF , SPF and tnF detected faults can als o be cleared rem otely by m eans of a logic input
or control bit ( [Fault reset] (rSF) param eter, page 251 ).
De te cte d Fault Nam e Probable cause Re m e dy
AnF [Load s lipping] •
The difference between the output
frequency and the speed feedback is not
correct.
•
Check the motor, gain and stabillity parameters.
•
Add a braking resistor.
• Check the size of the motor/drive/load.
•
Check the encoder's mechanical coupling and its w iring.
•
Check the setting of parameters
ASF [Angle Error] •
This occurs during the phase-shift angle
measurement, if the motor phase is
disconnected or if the motor inductance is
too high.
•
Check the motor phases and the maximum current allow ed
by the drive.
brF
[Brak e fe edback] •
The brake feedback contact does not
match the brake logic control.
•
The brake does not stop the motor quickly
enough (detected by measuring the
speed on the "Pulse input" input).
•
Check the feedback circuit and the brake logic control
circuit.
•
Check the mechanical state of the brake.
• Check the brake linings.
CrF1 [Pre charge] • Charging relay control detected fault or
charging resistor damaged. • Turn the drive off and then turn on again.
•
Check the internal connections.
•
Contact BLEMO Product Support.
EEF1 [Control Ee prom] •
Internal memory detected fault, control
block.
•
Check the environment (electromagnetic compatibility).
• Turn off, reset, return to factory settings.
•
Contact BLEMO Product Support.
EEF2 [Pow er Ee prom] •
Internal memory detected fault, power
card.
FCF1 [Out. contact.
s tuck ] •
The output contactor remains closed
although the opening conditions have
been met.
•
Check the contactor and its w iring.
•
Check the feedback circuit.
HdF [IGBT de s aturation] •
Short-circuit or grounding at the drive
output.
•
Check the cables connecting the drive to the motor, and the
motor insulation.
ILF [inte rnal com. link] •
Communication interruption betw een
option card and drive.
•
Check the environment (electromagnetic compatibility).
•
Check the connections.
•
Replace the option card.
•
Contact BLEMO Product Support.
InF1 [Rating e rror] •
The pow er card is different from the card
stored.
•
Check the reference of the power card.
InF2 [Incom patible PB] •
The pow er card is incompatible w ith the
control block.
•
Check the reference of the power card and its compatibility.
InF3 [Inte rnal s erial link]
•
Communication interruption betw een the
internal cards.
•
Check the internal connections.
•
Contact BLEMO Product Support.
InF4 [Inte rnal-mftg zone] •
Internal data inconsistent.
•
Recalibrate the drive (performed by BLEMO Product
Support).
InF6 [Inte rnal - fault
option] •
The option installed in the drive is not
recognized.
•
Check the reference and compatibility of the option.
•
Check that the option is w ell inserted into the ER24.
InF9 [Inte rnal- I
m e asure] •
The current measurements are incorrect.
•
Replace the current sensors or the pow er card.
•
Contact BLEMO Product Support.
InFA [Interna l- m a ins
circuit] • The input stage is not operating correctly. • Contact BLEMO Product Support.
InFb [Inte rnal- th.
s e nsor] • The drive temperature sensor is not
operating correctly. • Replace the drive temperature sensor.
•
Contact BLEMO Product Support.
InFE [inte rnal- CPU ] •
Internal microprocessor detected fault.
•
Turn off and reset.
•
Contact BLEMO Product Support.
SAFF [Safe ty fault] •
Debounce time exceeded.
•
SS1 threshold exceeded.
•
Wrong configuration.
•
SLS type overspeed detected.
•
Check the safety functions configuration.
•
Check the ER24 Integrated safety Functions manual
