Nominal
setting 1
The selected nominal setting group for the controller when Source is set to
Local .
Changing the nominal setting group using a digital input, analogue input, or
external command changes this parameter.

rules
Local
Local : The nominal setting selection is independent of the power management
rules. The selected nominal setting is the same regardless of the active power
management rule.
Changing the nominal setting group with a digital input, analogue input, or
external command, changes the nominal setting
Selection parameter for the
local settings.
Power management rules : The nominal setting depends on the active power
management rule. Each power management rule can determine which set of
nominal settings should be active at a given time.
Changing the nominal setting group with a digital input, analogue input, or
external command, changes the nominal setting
Selection parameter for the
active power management rules.
Configure this parameter under Configure > Parameters > Power management rules > Configuration # > Nominal settings >
Controller nominal setting , where # is 1 to 8.
Table 3.3 Power management nominal setting parameter
Parameter Range Default Notes
Selection
• Nominal setting 1
• Nominal setting 2
• Nominal setting 3
• Nominal setting 4
Nominal
setting 1
The selected nominal setting group for the controller when the Source
parameter ( Local > Nominal settings > Controller nominal settings ) is set
to Power management rules .
Changing the nominal setting group using a digital input, analogue input, or
external command changes this parameter.
3.2.2 Nominal power calculations
Configure the controller nominal power calculations under Configure > Parameters > [Source] > Nominal settings > Nominal
settings # > Calculation method , where # is 1 to 4.
Reactive power (Q) nominal
Some alarms and regulators use the nominal reactive power (Q). However, Q is not defined in the controller's nominal settings. The
controller therefore always calculates Q. You can select the method that the controller uses here.

Q nominal
calculated
Q nominal calculated : The controller calculates Q nominal based on S
nominal and the power factor.
Q nominal = P nominal : The controller uses the nominal power as the nominal
reactive power.
