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
b) P1000 = 2
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 com-
mand (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 P0700 or P1000 are modified, then the frequency inverter also changes
the subordinate BICO parameters (refer to the parameter list for P0700 or
P1000 in the appropriate tables)
There is no prioritization (priority assignment) between direct BICO
parameterization and P0700/P1000. The last modification is valid.
