Determines the source of the IR Compensation 2. The source selection
may be either the Speed Error Integral 03.08 (set to 0) or the final
current demand 04.02 (set to 1).

Provides the option of full or half control. Available only with the FXM5
Field Controller. To use FXM5 in Full Control mode, set 06.22 =1and
LK3 to Full Control position.
Setting this parameter to 1 reduces the field current gains by a factor of
2.
Setting this parameter to 1 reduces the field current gains by a factor of 4
Setting both 6.23 and 6.24 to 1 will result in the gains being reduced by
8.
