		CDP 31x				(FAULT_WORD_1/2)
display
F 8	Current rise fault		Actual current changed faster than allowed		11103		bit 10	(2)
			The rate of current change is monitored.
			Check: - Setting of current reference slope						S21.232
				[P406] and CURRENT_RISE_MAX
				[P418];					and
									higher
				Level and setting of line voltage
				and motor voltage; setting of
				current controler
F 14	Speed meas. fault		Speed feedback (measurement) fault		11102		bit 5	(3)
			Check: - Incremental encoder and connec-
				tion cable, encoder power supply
				(feedback might be too low);
				- Tacho polarity and voltage
				(does a total mismatch exist?)
				- Electronic boards SDCS-CON-x,
				SDCS-IOB-3, SDCS-POW 1;
				- Connection converter – armature
				circuit open?
				- Correct setting for selection of
				speed feedback monitoring?
F 17	Type coding fault		(Converter) Type coding fault		11102		bit 8	(1)
			SDCS-PIN-xx board not connected to board						Can
			SDCS-CON-x or SDCS-PIN-xx not coded.						not be
			Check: - Flat cables X12 and X13 O.K.?						reset
				- Faulty coding on SDCS-PIN-xx?
				- Correct coding of unit size C4?
			Note: This fault signal will be shown, if jumper S2 (on board
			SDCS-CON-x) is in position 1–2 while switching ON the elec-
			tronics supply. In that case select BACKUP-STOREMODE
			[11202], save the paramter set, switch OFF the electronics,
			reset jumper S2 and switch ON the electronics again.
F 18	Backup read fault		Backup read fault (Parameter saving fault)		11102		bit 9	(1)
			Cause: Wrong or missing checksum, data error						Can
			while writing or reading.						not be
			Note: Try again BACKUP-STORE-MODE; for that purpose						reset
			- Move jumper S2 (on board SDCS-CON-x) to Pos. 1–2
				with electronics supply switched OFF;
			-	Switch ON electronics again;
			- Select BACKUPSTOREMODE [11202];
			-	Save default parameter set;
			-	Switch OFF electronics;
			-	Reset jumper S2 to ist original position;
			-	Switch ON electronics again.
			If display shows F 18 once again, change SDCS-CON-x
			board!
