11.3. Alarm / fault indications
11.3.1. Messages
When a failure occurs in the drive or in the equipment monitored by the drive (eg,
main circuit breaker, transformer, cooling system), the CDP control panel displays
a corresponding alarm or fault message.
The message can be saved and viewed in the fault history of the drive when a PC
with the DriveWindow or DriveDebug is connected to the drive. The fault logger can
also be called up on the CDP control panel.
11.3.2. Error message levels
Two error message levels are used in the drive:
–
Alarm
: Does not shut down the drive. If the condition causing the alarm is not
corrected, a persisting alarm can lead to a fault. An alarm cannot be reset
manually. The alarm message is deleted from the display as soon as the alarm
condition has been corrected.
An exception is when an alarm of the cooling system (eg,
FanDiffPres
,
AirFiltSupv
)
is not reset automatically. To reset the alarm, set parameter
41.04 FanAlarmReset
to
RESET
.
–
Fault
: A fault shuts down the drive. The type of shutdown depends on the
origin of the fault. Depending on the type of fault, the drive opens the main
circuit breaker (MCB) or keeps it closed. A fault condition must be corrected
and the fault be manually reset before the drive can be started again.
11.3.2.1. Alarm / fault messages
If an alarm or a fault occurs, a specific message is saved in the fault buffer of the
drive. Information on the 64 most recent fault and alarm events are saved.
