12.15.2.3 Suppress diagnosc messages to the master
The alarm message on the master can be oponally suppressed for certain error responses of
the inverter to facilitate suitable error handling between master and slave (inverter). Alarm
responses programmed in the master can be avoided if they are not wanted in this case.
Details
Inverter errors and warnings are sent to the Master as alarm messages. This funcon is used
to suppress, for example, the fact that the "undervoltage DC link" warning triggers an alarm
and the associated control switches to the stop mode if there is no associated alarm block or
has been programmed manually. It should be noted here, that an alarm block not program-
med in the control can pose risks to the machine. A reducon of possible alarm messages
inially helps when the machine is commissioned. Later on, however, more eort should be
made to program the alarm blocks.
