F 28 Armature over-	Armature (DC circuit) overvoltage	11101 bit 2	(1)
voltage	Check: - Setting of param. [P 511] suitable
	for the system configuration?

-Setting of field current and actual value as well as the complete field supply (FIELD EXCITER);

-Was the motor accelerated by the load?

-Speed scaling;

-Armature voltage feedback;

-Connections between SDCS- CON-x and SDCS-PIN boards;

-Coding of voltage evaluation on SDCS-PIN-xx board.

F 29 Mains undervoltage Mains supply undervoltage (AC); setting via	11101 bit 11	(3)
parameter [P 509]
Check: - Does the supply voltage exist?

-Did the mains contactor close?

-Setting of voltage feedback coding (voltage scaling) correct?

-Connections between SDCS- CON-x and SDCS-PIN-xx boards;

-Coding of voltage evaluation on SDCS-PIN-xx board.
