SINAMICS S120 F07011: Drive Motor Overtemperature
What F07011 means
The motor's temperature sensor reported a temperature above the trip limit.
Symptoms
Trips after the axis has worked hard for a while, or right away if the sensor circuit is open.
Is it repairable?
Yes: sensor replacement, bearing work and rewinding are common motor repairs.
Common causes
- Motor overloaded
- Motor fan failed (on fan-cooled motors)
- High ambient temperature
- Faulty temperature sensor or broken sensor wiring
- Winding fault
Safe checks
- 1Feel whether the motor is actually hot
- 2Check the motor fan
- 3Measure the temperature sensor and its wiring with power off
Drives hold dangerous voltage after power-off. Checks should only be done by qualified personnel, with power isolated and the DC link discharged.
