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.
