4.17 Nominal settings
The nominal settings can be changed to match different voltages and frequencies. The GPC has four sets of
nominal values, and they are adjusted in menus 6000 to 6030 (nominal settings 1 to 4).
The possibility to switch between the four sets of nominal set points is typically used in appli-
cations where switching between 50 and 60 Hz is required.
Activation
The switching between the nominal set points can be done in three ways: digital input, AOP or menu 6006.
Digital input
M-Logic is used when a digital input is needed for switching between the four sets of nominal settings. Select
the required input among the input events, and select the nominal settings in the outputs.
Example:
Event A
