Operating Instructions

10.6 Warning and Alarm Messages

There is a clear distinction between alarms and warnings.
An alarm make the frequency converter 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 condition triggers a warning which disappears
when condition returns to normal, without interfering with
the process.
Warnings
A single bit within a warning word represents warnings
within the frequency converter. Bit status [0] False means
no warning, while bit status [1] True means warning. Any
bit change in the warning word is notified by a change of
bit 7 in the status word.
Alarms
Following an alarm message, the frequency converter
enters fault condition. When the fault has been removed
and the controller has acknowledged the alarm message
by setting bit 7 in the control word, the frequency
converter resumes operation. A single bit within an alarm
word represents alarms within the frequency converter. Bit
status [0] False means no fault, while bit status [1] True
means fault.
