F 65	Reversal Fault	Reversal of direction of current is not O.K.	11103 bit 15	(3)

The reversal of the direction of current was not correct.

Check: - External cabling between both thyristor power converters;

-Correct plugging in of flat cable X18:?

F 66 Current Difference	Current feedback difference (deviation) be-	11103 bit 14	(3)
	tween Master and Slave Drive

There is a current feedback difference (de- viation) between Master and Slave Drive (in twelve pulse configuration).

Check: - Parameter settings [P 3606] and [P 3605];

-Power-circuit cabling;

-Symmetry of control logic and scaling of signals exchanged between Master and Slave Drive.
