Optimizing EMERGENCY telegrams
In order to better handle Emergency telegram that are sent non-synchronously
when high bus load levels exist, there are various optimization methods.
Emergency messages can be suppressed by setting bit 31 in object 1014H (COB-
ID EMCY). Then, faults that occur are only displayed in the status word and can be
read-out of object 1003H.
Object 1014H also allows the COB-ID to be changed, which can then be used to
modify the priority of the message. Using the object 1015H (Inhibit Time EMCY), it
is possible to set a delay time for sending the EMCY message.
MICROMASTER 420/430/440 sends an Emergency message if an fault has
occurred in either the option module or in the inverter.
