ABB Error 50052 — Joint speed too high

Error

ABB 50052 (“Joint speed too high”): Joint speed too high: the resolver feedback indicates a joint speed above the permissible threshold. Likely part: Câble résolveur / Blindage / Belly pack (cable resolver / Blindage / Belly pack).

Updated 2026-10-22 · LogrobotLM reference

What it means

Joint speed too high: the resolver feedback indicates a joint speed above the permissible threshold. In the case of a hardware fault, this is a false detected movement and not an actual overspeed.

What to check

  • Check the measurement cable of the affected axis: shielding faults, dirty contacts, worn sheath.
  • Axis 4 is the most affected because its cable runs through the belly pack, which is subject to constant flexing.
  • Measure continuity and insulation, then replace the harness.
  • Check the SMB board if several axes are affected.
  • Note: Typical hardware cause mistaken for a software path fault. Correlate with 38209 (resolver) and 38104.
