ABB Error 39467 — Drive unit temperature warning

Error

ABB 39467 (“Drive unit temperature warning”): Drive unit temperature warning: the drive unit temperature supervision detects abnormal values on the axis PTC thermistor chain. Likely part: Drive Unit / Thermistances PTC (Drive Unit / Thermistances PTC).

Updated 2026-10-22 · LogrobotLM reference

What it means

Drive unit temperature warning: the drive unit temperature supervision detects abnormal values on the axis PTC thermistor chain.

What to check

  • Measure the PTC chain: approximately 75 ohms per axis at 25 °C, i.e. approximately 450 ohms (±10 %) for six axes in series.
  • A very high value = open circuit (cable/sensor); a very low value = short circuit.
  • Check ventilation, filters and ambient temperature before concluding that the drive unit electronics have failed.
  • Note: Thermal warning level on the drive unit side; see 20253 for the DRV1 external axis channel.
