6.2 FAULTS, ALARMS, AND POSSIBLE CAUSES
Table 6.1 -
Faults, alarms and possible causes
Fault/Alarm Description Possible Causes
F006:
Imbalance or
Input Phase Loss Phase missing in the input power supply or wrong
phase sequency.
;
CSR11 board connections.
;
Synchronism transformer connections.
;
Power supply connections.
F021:
DC Bus Undervoltage DC bus undervoltage condition occurred.
;
The input voltage is too low and the DC bus
voltage dropped below the minimum permitted
value (monitor the value at Parameter P0004):
Ud < 223 V - For a 200 / 240 V input voltage
(P0296 = 0).
Ud < 385 V - For a 380 V input voltage
(P0296 = 1).
Ud < 405 V - For a 400 / 415 V input voltage
(P0296 = 2).
Ud < 446 V - For a 440 / 460 V input voltage
(P0296 = 3).
Ud < 487 V - For a 480 V input voltage
(P0296 = 4).
Ud < 530 V - For a 500 / 525 V input voltage
(P0296 = 5).
Ud < 580 V - For a 550 / 575 V input voltage
(P0296 = 6).
Ud < 605 V - For a 600 V input voltage
(P0296 = 7).
Ud < 696 V - For a 660 / 690 V input voltage
(P0296 = 8).
; Phase loss in the input power supply.
;
Pre-charge circuit failure.
;
Parameter P0296 was set to a value above of
the power supply rated voltage.
F022:
DC Bus Overvoltage DC bus overvoltage condition occurred.
;
The input voltage is too high and the DC bus
voltage surpassed the maximum permitted
value:
Ud > 400 V - For 220 / 230 V input models
(P0296 = 0).
Ud > 800 V - For 380 / 480 V input models
(P0296 = 1, 2, 3 or 4).
Ud > 1000 V - For 500 / 600 V input models
(P0296 = 5, 6 or 7).
Ud > 1200 V - For 660 / 690 V input models
(P0296 = 8).
;
Inertia of the driven-load is too high or
deceleration time is too short.
;
Wrong settings for parameters P0151, or P0153,
or P0185.
F030

A047:
IGBT Overload Alarm A IGBT overload alarm occurred.
Note:
It may be disabled by setting P0350 = 0 or 2.
;
Converter input current is too high.
F048:
IGBT Overload Fault A IGBT overload fault occurred.
;
Converter input current is too high.
(*) For the Modular Drive it is not indicated in the HMI in which book happened the fault. For such, it is necessary to check the LED's at the
IPS1 board (refer to note
(1)
).
