12.16.2.2 Suppress diagnosc messages to the IO controller
Inverter errors and warnings are sent to the IO controller 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
programmed in the control can pose risks to the machine. A reducon of possible alarm mes-
sages inially helps when the machine is commissioned. Later on, however, more eort
should be made to program the alarm blocks.
Please note that an unprogrammed alarm block in the IO controller 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.
0x285A:001 serves to set which error response in the inverter suppresses the alarm message
to the IO-Controller.
