No connection between the inverter and the PROFIBUS
board (board was not recognized or has failed. See
parameter
E54 option module 1
).
Flashing Off
PROFIBUS master stopped bus for more than 25 s (PLC in
stop) or has failed or bus cable no longer connected (see
parameter
A84 PROFI-Baud
).
Off
Flashing Device is ready and is waiting for the PROFIBUS master to
start or:When this state does not change although the
PROFIBUS master has already attempted to establish a
connection, this means that the applicable function blocks
for PROFIBUS have not been downloaded to the inverter.
