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
– 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.
