NOTE

Communications between the AOP and MICROMASTER are established using the USS protocol. The AOP can be connected to both the BOP link (RS 232) as well as at the COM link interface (RS 485) of the drive inverter. If the AOP is to be used as command source or setpoint source then for parameter P0700 or P1000, either "USS on BOP link" or "USS on COM link" should be selected.

The complete list of all of the setting possibilities can be taken from the parameter list (refer to parameter list P1000).

Parameters P0700 and P1000 have the following default settings:

a)P0700 = 2 (terminal strip)

b)P1000 = 2 (analog setpoint)

In this case, the selection of the command source is made independently of the selection of the frequency setpoint source. This means that the source to enter the setpoint does not have to match the source to enter the power-on/power-off command (command source). This means, for example, that the setpoint (P1000 =

4)can be connected via an external device which is connected to the BOP link interface via USS and the control ON/OFF command, etc. is entered via digital inputs (terminals, P0700 = 2).

CAUTION

When modifying P0700 or P1000, then the drive inverter also changes the subordinate BICO parameters (refer to the parameter list for P0700 or P1000 and the appropriate tables)

No priority has assigned between the direct BICO parameterization and P0700/P1000. The last modification is valid.
