Temperature
Motor temperature > +150 °C (via resolver / encoder)
What does it mean?
Motor temperature detection via the resolver or incremental encoder exceeds the +150 °C threshold.
Common causes
- The motor is thermally overloaded: impermissible continuous current or frequent/too long acceleration.
How to fix it
- Check the drive dimensioning, correct the wiring, let the module cool with good ventilation
- if necessary, switch off the monitoring (C0583 = 3).
After troubleshooting: de-energise the device completely (disconnect the 24 V supply and discharge the DC bus) before opening the covers.
