Fault detection codes which require a power reset after the detected fault is cleared
The cause of the detected fault must be removed before resetting by turning off and then back on.
ASF, brF, SOF, SPF and tnF detected faults can also be cleared remotely by means of a logic input
or control bit ([Fault reset] (rSF) parameter, page 232
).
Detected Fault Name Probable cause Remedy
ASF
[Angle Error]
• For the law [Sync. mot.] (SYn), wrong
setting of the speed loop, when the
reference goes through 0.
• Check the speed loop parameters.
• Check the motor phases and the maximum current allowed
by the drive.
brF
[Brake feedback]
• 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
[Precharge]
• Charging relay control detected fault or
charging resistor damaged.
• Turn the drive off and then turn on again.
• Check the internal connections.
• Contact Schneider Electric Product Support.
EEF1
[Control Eeprom]
• Internal memory detected fault, control
block.
• Check the environment (electromagnetic compatibility).
• Turn off, reset, return to factory settings.
• Contact Schneider Electric Product Support.
EEF2
[Power Eeprom]
• Internal memory detected fault, power
card.
FCF1
[Out. contact.
stuck]
• The output contactor remains closed
although the opening conditions have
been met.
• Check the contactor and its wiring.
• Check the feedback circuit.
HdF
[IGBT desaturation]
• Short-circuit or grounding at the drive
output.
• Check the cables connecting the drive to the motor, and the
motor insulation.
ILF
[internal com. link]
• Communication interruption between
option card and drive.
• Check the environment (electromagnetic compatibility).
• Check the connections.
• Replace the option card.
• Contact Schneider Electric Product Support.
InF1
[Rating error]
• The power card is different from the card
stored.
• Check the reference of the power card.
InF2
[Incompatible PB]
• The power card is incompatible with the
control block.
• Check the reference of the power card and its compatibility.
InF3
[Internal serial link]
• Communication interruption between the
internal cards.
• Check the internal connections.
• Contact Schneider Electric Product Support.
InF4
[Internal-mftg zone]
• Internal data inconsistent. • Recalibrate the drive (performed by Schneider Electric
Product Support).
InF6
[Internal - fault
option]
• The option installed in the drive is not
recognized.
• Check the reference and compatibility of the option.
InF9
[Internal- I
measure]
• The current measurements are incorrect. • Replace the current sensors or the power card.
• Contact Schneider Electric Product Support.
InFA
[Internal-mains
circuit]
• The input stage is not operating correctly. • Contact Schneider Electric Product Support.
InFb
[Internal- th.
sensor]
• The drive temperature sensor is not
operating correctly.
• Replace the drive temperature sensor.
• Contact Schneider Electric Product Support.
InFE
[internal- CPU ]
• Internal microprocessor detected fault. • Turn off and reset.
• Contact Schneider Electric Product Support.
OCF
[Overcurrent]
• Parameters in the [SETTINGS] (SEt-)
and [MOTOR CONTROL] (drC-)
menus are not correct.
• Inertia or load too high.
• Mechanical locking.
• Check the parameters.
• Check the size of the motor/drive/load.
• Check the state of the mechanism.
• Decrease [Current limitation] (CLI).
• Increase the switching frequency.
SAFF
[Safe function fault]
• Debounce time exceeded.
• SS1 trip threshold exceeded.
• Wrong configuration.
• Check the safety functions configuration.
• Contact Schneider Electric Product Support.
