What it means

Resolver error: X/Y signal level out of range or inconsistent.

What to check

  • Check the resolver, connectors, resolver cable and SMB; look for short circuit/open circuit and loss of reference.
  • Redo the calibration only after eliminating the hardware cause.
  • Note: Very common on single or multiple axes. Several interventions link 38209 to cables, connections or the SMB.
