6.9.1 FAULT DETECTION MENU DESCRIPTION
TROUBLESHOOTING Section can provide additional information about Faults.
IGBT FAULT U PHASE/HS
Description: it detects the excess current or short circuit
condition of the output IGBT three-phase bridge
IGBT FAULT V PHASE/HS
Description: it detects the excess current or short circuit
condition of the output IGBT three-phase bridge
IGBT FAULT W PHASE/HS
Description: it detects the excess current or short circuit
condition of the output IGBT three-phase bridge
IGBT FAULT U PHASE/LS
Description: it detects the excess current or short circuit
condition of the output IGBT three-phase bridge
IGBT FAULT V PHASE/LS
Description: it detects the excess current or short circuit
condition of the output IGBT three-phase bridge
IGBT FAULT W PHASE/LS
Description: it detects the excess current or short circuit
condition of the output IGBT three-phase bridge
IGBT FAULT RECOVERY
Description: it detects the excess current or short circuit
condition of the recovery circuit IGBT
BUS OVERVOLTAGE
Description: it detects the DC BUS overvoltage condition; the
drive cuts off the current. This can be due to a recovery resistor
interruption or the resistor value is too high for the application
and it cannot dissipate the energy recovered by the motor and
the drive
BUS UNDERVOLTAGE
Description: it detects the DC BUS undervoltage condition;
the drive cuts off the current. This can be due to a power line
interruption or to an excessive current absorption by the drive
with respect to the resistor
UNSTABLE BUS
Description: it detects the DC BUS variation at DRIVE ON
when the supplied power is low (reduced or null speed). This
could be due to a fuse interruption on the three-phase line
NO BUS
Description: It detects the lack of DC BUS or a value lower
than 80 V (minimum default factory set value)
BUS/MOT.VOLTAGE UNCOMPATIBLE
Description: it detects the wrong setting of motor voltage
rating with respect to the voltage detected on DC BUS
RES.REC./MAIN UNCOMPATIBLE
Description: it indicates the wrong value of the used recovery
resistor in connection to the line voltage. A wrong Ohm-value
(lower than the recommended one) causes a recovery IGBT
damage due to overcurrent.
Attention: A value higher than the recommended one can
prevent braking in max supplied current condition at max
speed
SYSTEM ERROR ON VBUS DETECT.
Description: it indicates an anomaly inside the voltage reading
system on DC BUS. Try to switch the drive off and cut off the
line. In case the FAULT persists, the drive is broken
