5.11.1.2 AFE operation mode selection
When using digital input P2.4.2.17 AFE Mode 2 and P2.4.2.18 AFE Mode 3 with the parameters below,
it is possible to select the operation independently for both the digital inputs.
2.11.10.1 AFE Mode 1
Only active when P2.11.1 is 6/Free select.
0= AFE
1= Island
2= Micro Grid
2.11.10.2 AFE Mode 2
Only active when P2.11.1 is 6/Free select.
0= AFE
1= Island
2= Micro Grid
2.11.10.3 AFE Mode 3
Only active when P2.11.1 is 6/Free select.
0= AFE
1= Island

Synch to external grid

This function is used to synchronise to an external grid. Measurements with OPT-D7 are necessary
for the use of this function.
2.12.1 Synch. Offset
Used to compensate angle offset between the drive output terminals and OPT-D7
measurement point. E.g. with Dyn11, the transformer angle offset is usually 30.0 degree.
This equals as 512 for this parameter. (3072 equals 180 degrees offset). If possible, run
in AFE mode and see monitoring variable "D7 Synch. Error" to see what is needed for the
offset.
