Warning and Alarm Messages
There is a clear distinction between alarms and warnings. When there is an alarm, the frequency converter
will enter a fault condition. After the cause for the alarm has been cleared, the master will have to
acknowledge the alarm message before the frequency converter can start operating again. A warning, on
the other hand, may come when a warning condition appears, then disappear when conditions return to
normal, without interfering with the process.
Warnings
Warnings within the frequency converter are represented by a single bit within a warning word. A warning
word is always an active parameter. Bit status FALSE [0] means no warning, while bit status TRUE [1] means
warning. Any bit change in the warning word will be notified by a change of bit 7 in the status word.
Alarms
Following an alarm message the frequency converter will enter Fault condition. Only after the fault has been
alleviated and the master has acknowledged the alarm message by setting bit 7 in the control word, can the
frequency converter resume operation. Alarms within the frequency converter are represented by a single bit
within an alarm word. An alarm word is always an action parameter. Bit status FALSE [0] means no fault,
while bit status TRUE [1] means fault.

Fault Messages via DP Diagnosis

The standard DP function features an on-line diagnosis, which is active during DP initialisation as well as
data exchange mode.
