Identication power units
The pc-board DK-MAPRO is reading the conguration of the power units during the initialisation. On the primary
sides (pc-board DCDRV) the conguration is set by a DIP switch. On the secondary sides at AC/DC machines
(pc-board ACDRV) the conguration is set by a small jumper. The secondary side of the DC machines are the pc-
board KSDCN, which have a xed (not setable) conguration.
If the DK-MAPRO detects a non valid conguration, it will display the error code E25 (Powermodul detection).
