Operating Instructions

AOP Overview
Siemens Building Technologies, Inc. 7
If the AOP is the command source for the SED2, set USS Telegram Off Time for Serial
Interface BOP Link P2014[1]=5000 (5 seconds). To do this, first set P0003=3. The
P2014[1]=5000 setting causes the drive to trip if communications with the AOP control source
is lost.
If you have problems connecting to the SED2 drives, set the Auto Baud to OFF and the
default baud rate to the same as the SED2.
