GS8048 Power Save Priority

Forcing Specific Slaves to be Active:
It is possible to raise the priority of a slave and force it to activate. This is done by setting the master
rank higher than that slave. However, the

Master Power Save Level scale is not the same as the Slave

level.

Slave level settings apply to the whole inverter. Master level settings are applied per module.

This means that increasing the master by one rank will only turn on one additional module. To

completely turn on a slave inverter, the master must be increased two ranks. See the next page.
In Table 2, instead of loads, the number on the far left of each line shows the master increased by one

rank. (This example is otherwise the same as Figure 8.)
The last line of the table shows the master increased to 3, which is the same as the rank of the highest

slave. However, this only activates the first of the three slaves. The master would need to be set to

rank 7 to activate all slaves.
