Description of fault
Operating Instructions
Fault messages
Check
• phase L1 for short circuit or earth fault
(-X2:U2 - including motor).
• the contacts on the CU.
Check
• phase L2 for short circuit or earth fault
(-X2:V2 - including motor).
• the contacts on the CU.
Check
• phase L3 for short circuit or earth fault
(-X2:W2 - including motor).
• the contacts on the CU.
Defect in the measured value sensing circuit
Defect in the power section (valve is not blocking)
Check the DC link
Check the load connected to the DC link
Check
• 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
Check
• 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
Check:
Maximum connected inverter power greater than
4 x AFE inverter power?
If No: Check the DC link
If Yes: Contact your local SIEMENS AG branch
