				Fault messages
	No.			Description of fault		Remedial measures
	F025		UCE Ph. L1		Check
			A UCE shutdown has occurred in phase L1		•	phase L1 for short circuit or earth fault
						(-X2:U2 - including motor).
					•	the contacts on the CU.
	F026		UCE Ph. L2		Check
			A UCE shutdown has occurred in phase L2		•	phase L2 for short circuit or earth fault
						(-X2:V2 - including motor).
					•	the contacts on the CU.
	F027		UCE Ph. L3		Check
			A UCE shutdown has occurred in phase L3		•	phase L3 for short circuit or earth fault
						(-X2:W2 - including motor).
					•	the contacts on the CU.
	F029		Meas. val. sensing		Defect in the measured value sensing circuit
			A fault has occurred in the measured value sensing		Defect in the power section (valve is not blocking)
			circuit.
			•	(r949 = 1) Offset cannot be adjusted in phase L1.
			•	(r949 = 2) Offset cannot be adjusted in phase L2.
			•	(r949 = 3) Offset cannot be adjusted in phases L1 and
				L3.
	F030		DC-link short circuit		Check the DC link
			A short circuit has been detected during DC-link
			precharging.
	F035		Ext. fault 1		Check
			Parameterizable external fault input 1 has been activated		•	whether an external fault has occurred
					•	whether the lead to the appropriate digital input is
						interrupted
					•	P575 Src No Ext Fault1
					See section "Digital inputs" in Operator's Guide
	F036		Ext. fault 2		Check
			Parameterizable external fault input 2 has been activated		•	whether an external fault has occurred
					•	whether the lead to the appropriate digital input is
						interrupted
					•	P586 Src No Ext Fault2
					See section "Digital inputs" in Operator's Guide
	F039		DC link ground fault		Check:
			An earth fault has been detected during DC-link		Maximum connected inverter power greater than
					4 x AFE inverter power?
			precharging
					If No: Check the DC link
					If Yes: Contact your local SIEMENS AG branch
	F040		AS internal		Replace the CUSA (-A10) board
			Incorrect operating status
	F041		EEprom fault		Replace the CUSA (-A10) board
			A fault occurred as values were been saved to the
			EEPROM
	F042	Comp. time			Reduce the computation time load, increase P308
			Computation time problems		Sampling time,
					check r725 Available computation time.
	F045		Opt.brd.HW		Replace the CUSA board
			A hardware fault occurred as an option board was being		Check the connection between the subrack and option
			accessed
					boards
