Why is my HSD ES915 electrospindle not rotating?
- XxmorrisAug 1, 2025
The electrospindle might not be rotating due to several reasons: There could be no power supply, so check the mains voltage, connectors, and the integrity of electrical connections. Ensure a tool-holder is properly inserted. The thermal protective device might have tripped; if so, wait for the electrospindle to cool down. Lastly, the sensor S1(ISO30) or the series of sensors (HSK) might be disconnected or faulty, so check their connectors and electrical connections; adjust or replace the faulty sensor if needed.
