AOP Operating Modes

Siemens Building Technologies, Inc. 21

Operating in Master Mode (Broadcast Operation)

In master mode, the network controls the SED2 VFDs either individually or by broadcast

operation. A broadcast operation can simultaneously start or stop all networked SED2 VFDs.

While in broadcast operation, note the following AOP functions:

• Since parameters can not be edited globally, does not function in a broadcast operation.

• and still function in a broadcast operation. For example, it would be possible to change

the speed of a motor simultaneously across all networked SED2 VFDs.

• If a ‘Communications Failure’ displays, the screen also indicates which slave SED2 VFD is

not working correctly. Press

to acknowledge the warning condition.

If the warning condition occurs again, the AOP assumes it is not connected to the SED2 VFD

and returns you to the main menu.

Communications Failure

If communications between the AOP and a SED2 VFD fails, a warning screen displays. Press

to acknowledge the warning condition. If the warning condition occurs again, the AOP assumes it

is not connected to the SED2 VFD and returns you to the main menu.

If the AOP fails to establish initial communications with a SED2 VFD, any attempt to select

Operate from the main menu results in an warning screen. Press

to acknowledge the warning

condition and to return to the main menu.

Displaying Drive Status

The AOP can monitor the status of its associated SED2 VFD and motor. The screen displays the

current activity of the SED2 VFD and motor, including any fault conditions.

Verifying Drive Type

The AOP can verify the type of its associated SED2 VFD. If the SED2 VFD type is incompatible

with the AOP, it inhibits operation and returns to the main menu.
