8.2.6 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, will 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.

8.2.7 Fault Messages via DP Diagnostics

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