F10
Line Synchronization Fault
Vacon · NXP AFE-II Drive
What does F10 mean?
The drive has detected a missing input line phase, as indicated by phase supervision for both diode supply (S1) and active front end (S2). This means one or more incoming power phases are not present or severely degraded. Running with a missing phase can cause damage to the drive and connected equipment.
Complete Troubleshooting Guide
- 1
Check the incoming supply voltage at all phases.
- 2
Inspect all input fuses for continuity and replace any blown fuses.
- 3
Examine the input power cables for damage or loose connections.
