In the table, the set baud rate is entered from the parameter
Baud-Rate 903 in
kBaud. For each frequency inverter, the set time for the transmission interval (e.
g.
TxPDO1 Time 931) in ms is entered for the TxPDO being used at the time. In the
column Load the bus load caused by the individual TxPDO appears, under
Total
Load the entire bus load.
For the bus load (Total load) the following limits have been defined:
≤
80 %
Î
OKAY
80 ... 90 %
Î
CRITICAL
> 90 %
Î NOT POSSIBLE
