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 and 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.
Note: 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.
11.3.3 Fault handling
The faults are entered into the fault logger as they occur and are numbered:
- The last fault entered always has number 1 assigned to it.
- The first fault always has the highest number in the fault buffer.
Date and time stamps facilitate fault tracing, especially when a fault leads to several
subsequent faults.
