Micro Grid

2.11.1 Control Mode
Select the AFE operation mode.
0 = AFE
Standard AFE functionality, no license key required. Keeps fixed DC-Link Voltage.
1 = Island
Island operation mode, cannot operate parallel with other power sources. Makes fixed
voltage and frequency, i.e. no voltage or frequency drooping. Also low DC-Link Voltage
limitation function is disabled. Reacts only to set DC Under Voltage limit.
2 = Micro Grid
uGrid operation mode, can operate parallel with other power sources. Parallel operation
is achieved by voltage and frequency drooping. Start to reduce output frequency when
not sufficient DC-Link Voltage, this will prevent reactive current generation in case of
low power in DC-Link side.
3 = Island-AFE
The drive changes the control mode automatically when feedback from the external net
contactor has been received.
4 = Island-Micro Grid
The drive changes the control mode automatically when feedback from the external net
contactor has been received.
5 = (Reserved)
6 = Free Select
The operation mode is selected by digital inputs and AFE mode 1-3 selections.
NOTE! A licence is necessary for other than the standard AFE mode.
